Abstract
An implantation instrument for implanting a substantially solid material, including solid medication or drugs, in a subcutaneous location and method are described. An incising shaft includes a beveled tip with a cutting edge along a distal end. A syringe body is affixed to a proximal end of the incising shaft. The syringe body and the incising shaft each define a substantially non-circular hollow bore extending continuously along a shared longitudinal axis. The incising shaft bore does not exceed the syringe body bore in girth. Both the incising shaft bore and the syringe body bore are sized to receive the solid material. A plunger is conformably shaped to the syringe body bore and has an end piece facilitating deployment of the plunger assembly. The plunger slidably fits within the syringe body bore and advances the solid material through the syringe body bore and the incising shaft bore into the subcutaneous location.
Description
- This patent application is a continuation of U.S. patent application Ser. No. 09/644,666, filed Aug. 24, 2000, pending, the priority date of which is claimed and the disclosure of which is incorporated by reference.
- The present invention relates in general to subcutaneous implantation instruments and methods and, in particular, to an instrument for implanting sensors and solid materials in a subcutaneous location and method thereof.
- A major part of health care assessment involves the review and analysis of physiological measurements collected and recorded by electronic data sensors. In addition to vital signs, physiological measures can include detailed measurements of organ functions, body fluid chemistry and rates, activity levels, and similar measures, both measured directly and derived.
- The type and quality of physiological measures depends greatly on the type and location of the sensor employed. External sensors, such as thermometers, blood pressure cuffs, heart rate monitors, and the like, constitute the most common, and least invasive, form of sensors. However, these sensors are extremely limited in the kinds of information which they are able to collect and encumber the patient with wearing and maintaining an external sensor. On the other extreme, implantable in situ sensors provide the most accurate and continuous data stream through immediate proximity to organs and tissue of interest. However, implantable sensors are invasive and generally require surgery for implantation.
- Recent advances in microchip technology have created a new generation of highly integrated, implantable sensors. For instance, PCT Application Nos. PCT/GB99/02389, to Habib et al., filed Jul. 22, 1998, pending, and PCT/GB99/02393, to Habib et al., filed Jul. 22, 1998, pending, respectively describe an implantable sensor chip and treatment regiment, the disclosures of which are incorporated herein by reference. The sensor chip is adapted to receive and rectify incoming electromagnetic signals and to transmit data relating to treatment parameters by wireless telemetry to a receiver external to a body. Similarly, the emerging Bluetooth wireless communication standard, described at http://www.bluetooth.com/developer/specification/specification.asp, proposes a low cost, small form factor solution to short range data communications, potentially suitable for use in implantable sensor technology.
- Even though implantable sensor technology is trending towards smaller and more specialized microchip sensors, in humans, these sensors must still be implanted via surgical procedure. Minimally invasive implantation using large bore needles is impracticable because sensors, particularly when embodied using microchip technology, favor a prismatic shape with substantially rectangular cross sections. A large bore needle can cause a core of flesh or skin (or hide, when used in domesticated animals) to form in the pointed tip as the needle is inserted. Cylindrical needles also severely limit solid sensor sizes, shapes and dimensions to only those that can be inserted through a circular bore.
- Although current surgical approaches attempt to minimize the size of incision and decree of invasion, implantation is, at best, costly, time-consuming, traumatic, requires multiple instruments and maneuvers, and potentially risky to the patient. Subcutaneous implantable sensors offer the best compromise between in situ sensors and external sensors and are potentially insertable with a simple injection. These sensors are typically implanted below the dermis in the layer of subcutaneous fat. The subcutaneous implantation of solid materials has been described in the prior art as follows.
- An insertion and tunneling tool for a subcutaneous wire patch electrode is described in U.S. Pat. No. 5,300,106, to Dahl et al., issued Apr. 5, 1994. The tunneling tool includes a stylet and a peel-away sheath. The tunneling tool is inserted into an incision and the stylet is withdrawn once the tunneling tool reaches a desired position. An electrode segment is inserted into the subcutaneous tunnel and the peel-away sheath is removed. Although providing a tool for subcutaneous implantation, the Dahl device requires an incision into the subcutaneous fat layer and forms an implantation site larger than the minimum sized required by the electrode segment. Further more, the cylindrical bore precludes the injection of non-conforming solid sensors or materials.
- An implant system for animal identification that includes a device for implanting an identification pellet in a fat layer beneath the hide or skin of an animal is described in U.S. Pat. No. 4,909,250, to Smith, issued Mar. 20, 1990. The device includes a curved needle-like tube that terminates at a tapered, sharpened point. An elongated, flexible plunger is slidably received within the needle-like tube. The pointed tip is inserted through the hide or skin and the plunger is actuated to drive the identification pellet from the tip into the fat layer. However, the Smith device uses an oversized open bore which can cause coring of the hide or flesh.
- A trocar for inserting implants is described in PCT Application No. PCT/US99/08353, to Clarke et al., filed Oct. 29, 1999, pending. An implant retention trocar includes a cannula for puncturing the skin of an animal and an obturator for delivering the implant. A spring element received within the cannula prevents an implant from falling out during the implant process. The cannula has a distal tip design which causes a minimum of trauma and tearing of tissue during implant insertion. However, the distal tip design is specifically directed to cannulas having a substantially circular bore and thereby limits the size and shape of implant which can be inserted through the Clarke trocar.
- An instrument for injecting implants through animal hide is described in U.S. Pat. No. 5,304,119, to Balaban et al., issued Apr. 19, 1994. The instrument includes an injector having a tubular body divided into two adjacent segments with a hollow interior bore. A pair of laterally adjacent tines extend longitudinally from the first segment to the distal end of the tubular body. A plunger rod has an exterior diameter just slightly larger than the interior diameter of the tubular body. With the second segment inserted beneath the animal hide, the push rod is advanced longitudinally through the tubular body, thereby pushing the implant through the bore. As the implant and rod pass through the second segment, the tines are forced radially away from each other, thereby dilating or expanding the incision, and facilitating implant. The instrument is removed from the incision following implantation. Though avoiding the coring of animal hide or flesh, the instrument forms an implantation site larger than the minimum sized required by the implant and causes potentially damaging compaction of the implant against the laterally adjacent times during implant delivery.
- Therefore, there is need for a non-surgical instrument and method for subcutaneous implantation of sensors and solid materials that preferably does not require an incision preparatory to instrument insertion.
- There is a further need for a subcutaneous implantation instrument and method capable of implanting sensors and other solid materials that are not readily disposed to implantation through a substantially circular bore.
- Moreover, there is a further need for a subcutaneous implantation instrument and method which is minimally invasive, preferably creating the smallest needed implantation site, and capable of implantation without exposing the implant to longitudinal stresses.
- The present invention provides an implantation instrument and method of use for implanting sensors and other solid materials in a subcutaneous or other site. As used herein, “subcutaneous” refers generally to those implantation sites located within a body below the skin. The implantation instrument consists of an incising shaft attached to a syringe body. The syringe body and incising shaft both define a substantially non-circular hollow bore for accommodating the sensor or solid material. The subcutaneous site is formed by a cutting edge on the distal end of the incising shaft. The subcutaneous site can be cleared using a clearing trocar slidably received within the hollow bore. The sensor or solid material is advanced through the hollow bore and delivered into the subcutaneous site. The depth of the subcutaneous site can be limited using a penetration limiting mechanism.
- An embodiment of the present invention is an implantation instrument for implanting a substantially solid material in a subcutaneous body location. An incising shaft defines a substantially non-circular hollow bore extending continuously along a longitudinal axis. The incising shaft has a beveled tip forming a cutting edge on a distal end thereof and is sized to receive a substantially solid material for implant. The solid material, which can include a sensor, is preferably protected against damage by encasement within, for example, a mannitol pellet or similar carrier. The solid material can also be encased in titanium, silicone, epoxy, or other similar, functionally inert protective material. A delivery mechanism receives the incising shaft and includes a pushing device facilitating deployment of the substantially solid material through the incising shaft bore and into an implantation site.
- A further embodiment of the present invention is a subcutaneous implantation instrument for implanting a substantially solid material. An incising body includes a syringe body and an incising shaft. The syringe body and the incising shaft each define a substantially non-circular hollow bore extending continuously along a shared longitudinal axis. The incising shaft includes a beveled tip with a cutting edge on a distal end. Several prismatic or non-cylindrical bore shapes are possible. The incising shaft bore and the syringe body bore both are sized to receive the solid material. A delivery assembly includes a plunger slidably fitted within the syringe body bore. The plunger is conformably shaped to the syringe body bore with an end piece facilitating deployment of the substantially solid material into an implantation site.
- A still further embodiment of the present invention is an implantation instrument for implanting a substantially solid material in a subcutaneous location. An incising shaft includes a beveled tip with a cutting edge along a distal end thereof. A syringe body is affixed to a proximal end of the incising shaft. The syringe body and the incising shaft each define a substantially noncircular hollow bore extending continuously along a shared longitudinal axis. The incising shaft bore does not exceed the syringe body bore in girth. Both the incising shaft bore and the syringe body bore are sized to receive the solid material. A plunger is conformably shaped to the syringe body bore and has an end piece facilitating deployment of the plunger assembly, the plunger slidably fits within the syringe body bore and advances the solid material through the syringe body bore and the incising shaft bore into the subcutaneous location.
- A still further embodiment of the present invention is a method for implanting a substantially solid material in a subcutaneous location. A beveled tip of an incising shaft with a cutting edge along a distal end thereof is inserted into an implantation site. A proximal end of the incising shaft is affixed to a distal end of a syringe body. The syringe body and the incising shaft each define a substantially non-circular hollow bore extending continuously along a shared longitudinal axis. The incising shaft bore do not exceed the syringe body bore in girth. Both the incising shaft bore and the syringe body bore are sized to receive the solid material. The solid material is advanced through the syringe body bore and the incising shaft bore into the subcutaneous location through deployment of a plunger conformably shaped to the syringe body bore. The deployment is effected via actuation of an end piece on a distal end of the plunger. The plunger slidably fits within the syringe body bore.
- Still other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein is described embodiments of the invention by way of illustrating the best mode contemplated for carrying out the invention. As will be realized, the invention is capable of other and different embodiments and its several details are capable of modifications in various obvious respects, all without departing from the spirit and the scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.

- FIG. 1 is a perspective view of an
instrument 10 for implanting sensors or solid materials in a subcutaneous or other tissue location in accordance with the present invention. Theimplantation instrument 10 consists of two principal groups of components, an incising body consisting of an incisingshaft 11 and asyringe body 15, and a delivery assembly consisting of aplunger assembly 20. The delivery assembly is received into the syringe body bore by sliding theplunger assembly 20 throughproximal bore opening 19. - The incising
shaft 11 is formed with a beveled and roundedtip 12 that tapers into a surgicallysharp cutting edge 13 formed on a distal edge. Thebeveled tip 12 includes a distal bore opening 14 through which the sensor or solid material is delivered into the implantation site. - In the described embodiment, the sensor or solid material (implant) has approximate dimensions of 5 mm by 10 mm by 20 mm. The critical dimension is the cross-sectional profile, that is, the height and width, of the implant which must conform to passage through the syringe body and incising shaft bores. Other nonlinear, prismatic shapes are equally usable provided the implant can fit within the confines of the syringe body and incising shaft bores. The implant could also be folded or compacted to minimize the cross-sectional profile with the implant unfolding or expanding upon implantation. As well, the implant is preferably protected against damage by encasement within, for example, a mannitol pellet in the case of a solid drug delivery system or epoxy in the case of an implantable sensor.
- An implantable sensor microchip suitable for use in the present invention is described in PCT Application No. PCT/GB99/02389, to Habib et al., filed Jul. 22, 1998, pending, the disclosure of which is incorporated herein by reference. Such a sensor could be used for monitoring and collecting physiological or chemical measures. Similar devices for therapeutic uses, including treating cancer, and for health care giving, including administering solid medication in the form of boluses, are possible. As well, the present invention has equal applicability to implantation of sensors, including location and identification sensors, and solid materials in domesticated animals. The sensor could also constitute or include a data transmitter with which to exchange information and telemetered signals.
- The incising
shaft 11 is fixably attached to thesyringe body 15 through frictional, adhesive, or preformed constructive means, as is known in the art. Both the incisingshaft 11 andsyringe body 15 define a substantially non-circular hollow bore extending continuously along a shared longitudinal axis, as further described below with reference to FIGS. 5A-D. - The plunger assembly includes a
plunger 16, an interconnectingplunger shaft 17 and aplunger end piece 18. Theplunger 16 is conformably shaped to fit within the syringe body bore. Theplunger end piece 18 facilitates deployment of the plunger assembly through the syringe body bore and is preferably shaped to fit a thumb or palm impression. - In the described embodiment, the
implantation instrument 10 is designed for inexpensive and disposable use utilizing low-cost, sanitizable materials. The incisingshaft 11 can be fashioned from surgical grade stainless steel and has the approximate dimensions of approximately 10 mm by 5 mm in cross section. The incisingshaft 11 is approximately 50 mm long and the length can be varied to accommodate different implantation depths. Theplunger 16 is formed from plastic and rubber and preferably forms a watertight seal within the syringe body bore and has the approximate dimensions of approximately 8 mm by 3 mm in cross section. Theplunger shaft 17 andplunger end piece 18 are formed from plastic or similar material. Other materials, as would be recognized by one skilled in the art, could be substituted. - In a further embodiment, the
syringe body 15 and plunger assembly can be replaced by an automated injection system, such as used with immunization injection guns or similar devices. These devices typically employ compressed air or other inert gases to administer medication in lieu of manual plungers. Other automated variations include spring-loaded and similar mechanical injection systems. The incisingshaft 11 is fixably attached to the automated injection system which functions as a delivery mechanism in place of thesyringe body 15 and plunger assembly. Thus, the implant would be pushed through the incising shaft bore using the compressed air or gas, or mechanical equivalent. - FIG. 2A is a longitudinal cross-sectional view of the
implantation instrument 10 with astraight incising shaft 11. The hollow bore defined by both the incisingshaft 11 and thesyringe body 15 runs along a common shared axis. The incising shaft bore 22 is sized to allow the implant to advance smoothly into the implantation site under the forward lateral urging of theplunger assembly 20. The syringe body bore 23 must be at least as large as the incising shaft bore 22, but can be slightly larger to accommodate lubricants, anesthetizing agents, or similar coatings, such as mannitol, applied over the sensor or solid material. - The
syringe body 15 preferably includes acircular collar 21, pair of winglets, ears, or eyelets, or similar structure, optionally formed on a proximal end of thesyringe body 15 to assist a user in depressing theplunger assembly 20. - FIG. 2B is a longitudinal cross-sectional view of the implantation instrument with a
curved incising shaft 24. Thecurved incising shaft 24, as well as thesyringe body 15 and related components, are shaped into a substantially continuous curve along the ventral side. The curvature helps regulate the penetration depth of the incising shaft and, in the described embodiment, has an arc of approximately 20 degrees. - FIG. 3 is a diagrammatic view illustrating the implantation of a
sensor 28 or solid material into a subcutaneous site. Prior to delivery, thesensor 28 is fed through the proximal bore opening 19 of thesyringe body 15 and then further advanced through the syringe body bore 23. During operation, the incisingshaft 11 is inserted through thedermis 25 and guided into the layer ofsubcutaneous fat 26, above the layer ofmuscle 27. Thesensor 28 is then advanced through the incising shaft bore 22 by theplunger 16 into the subcutaneous site. Note that although the foregoing view illustrates an implant into the subcutaneous fat layer, one skilled in the art would appreciate that subcutaneous implantation locations are not strictly limited to the subcutaneous fat layer and are generally termed as those implantation locations situated within a body under the skin. - FIG. 4A is a diagrammatic view illustrating the clearing of a subcutaneous site using the
implantation instrument 10 fitted with aclearing trocar 29 in accordance with a further embodiment. Theclearing trocar 29, as further described below with reference to FIG. 6, is mounted to its own handle or plunger assembly and has asharp cutting tip 30 for optionally clearing a subcutaneous site prior to delivery of the implant. - Prior to implantation, the
clearing trocar 29 is slidably received into thesyringe body 15 and is advanced until the cuttingtip 30 is even with the proximal bore opening 19 of the incisingshaft 11. During operation, the incisingshaft 11 andclearing trocar 29 are inserted through thedermis 25 and guided into the layer ofsubcutaneous fat 26, above the layer ofmuscle 27. - The
cutting edge 13 of thebeveled tip 12 makes an entry incision through thedermis 25 and is laterally pushed into thesubcutaneous fat 26 until thecutting edge 13 is adjacent to the subcutaneous site. Theclearing trocar 29 is then urged through thesubcutaneous fat 26 by advancement of its handle or plunger assembly to prepare the implantation site for delivery of thesensor 28 or solid material. Theclearing trocar 29 is then withdrawn from the subcutaneous site and out of theimplantation instrument 10. - FIG. 4B is a diagrammatic view illustrating the subcutaneous implantation of a
sensor 28 using theimplantation instrument 10 fitted with a pushingstylet 31 in accordance with a further embodiment. The pushingstylet 31, as further described below with reference to FIG. 7, has ablunt tip 32 for advancing the sensor 28 (or solid material) through the syringe body bore 23 and incising shaft bore 22 and into the subcutaneous site. The cross section of the pushingstylet 31 closely conforms to the incising shaft bore 22 while theplunger 16 closely conforms to the syringe body bore 23. The pushingstylet 31 thus extends the reach of theplunger assembly 20 and allows the syringe body bore 23 to have a different cross-section than the incising shaft bore 22. - The pushing
stylet 31 is used while the incisingshaft 11 is in situ in thesubcutaneous layer 26. Prior to delivery, thesensor 28 is fed through the proximal bore opening 19 of thesyringe body 15 and further advanced within the syringe body bore 23 by contact with theplunger 16. The pushingstylet 31 is slidably received into thesyringe body 15 and is advanced until theblunt tip 32 contacts thesensor 28. During operation, thesensor 28 is urged through the incising shaft bore 22 by the pushingstylet 31 and into the subcutaneous site by advancement of the plunger assembly. Upon delivery of thesensor 28 into the subcutaneous site, the incisingshaft 11 and pushingstylet 31 are withdrawn. - Although operation of the
implantation instrument 10 is described with reference to the implantation of sensors or solid materials into a subcutaneous site situated within the layer ofsubcutaneous fat 26, implantations could also be effected in other subcutaneous, intramuscular, intraperitoneal, intrathoracic, intracranial, intrajoint, as well as other organ or non-subcutaneous sites, as would be recognized by one skilled in the art. In addition, the foregoing procedure could be modified to forego the use of theclearing trocar 29 forsmall sensors 28 or solid materials. The clearing effect of theclearing trocar 29 can be approximated by use of the incisingshaft 11 alone whereby the incisingshaft 11 is inserted into the subcutaneous site and then withdrawn by reverse deployment, thereby forming a slightly overwide implantation site. - The operations of subcutaneous implantation can be carried out over a plurality of sites and with the same or
different sensors 28 and solid materials. Similarly,several sensors 28 and solid materials could be implanted at the same subcutaneous site during a single implantation operation. - FIGS.5A-D are transverse cross-sectional views of the
implantation instrument 10 illustrating, by way of example, various bore configurations. FIG. 5A illustrates an incisingshaft 35 with a substantiallyrectangular bore 36. FIG. 5B illustrates an incisingshaft 37 with a substantially square bore 38. FIG. 5C illustrates an incisingshaft 39 with a substantiallyoval bore 40. And FIG. 5D illustrates an incisingshaft 41 with a substantiallyhexagonal bore 42. Note the circumferential shape of the incising shaft need not follow the internal shape of the incising shaft bore. Other bore configurations, including variations on oval, rectangular, square, pentagonal, hexagonal, heptagonal, octagonal, and similar equilateral or non-equilateral shapes, are feasible. - In the described embodiment, the
rectangular bore 36 has the dimensions of approximately 10 mm by 5 mm. The syringe body bore 23 has a length of approximately 5 cm. - FIG. 6 is a segmented side view of a
clearing trocar 45. Theclearing trocar 45 consists of a beveled tip 47 on the distal end of theclearing trocar 45 and aclearing trocar shaft 46 affixed, either fixably or removably, to the distal end of aplunger 16. - During a clearing operation, the
clearing trocar 45 is fully extended from the distal bore opening 14 of the incisingshaft 11. Theclearing trocar shaft 46 is only long enough to clear out the subcutaneous site. Theplunger 16 acts as a stop that limits the extent of penetration of theclearing trocar 45, thereby preventing theclearing trocar 29 from incising too deeply into thesubcutaneous fat 29. In addition, theclearing trocar 29 is sized to approximate the girth of the incising shaft bore 22 and will clear a subcutaneous site only as wide as minimally necessary to facilitate implantation of the sensor or solid material. In the described embodiment, theclearing trocar 45 has a length of approximately 2 cm beyond the tip of thesyringe body 15. - FIG. 7 is a segmented side view of a pushing
stylet 50. The pushingstylet 50 consists of ablunt tip 52 on the distal end of the pushingstylet 50 and a pushingstylet shaft 51 affixed, either fixably or removably, to the distal end of aplunger 16. - During a delivery operation, the pushing
stylet 50 is extended from the distal bore opening 14 of the incisingshaft 11. The pushingstylet shaft 51 is only long enough to clear thedistal bore opening 14. Theplunger 16 acts as a stop that limits the lateral travel of the pushingstylet 50. In the described embodiment, the pushingstylet 50 has an additional length of approximately 2 cm beyond the tip of thesyringe body 15. - FIGS.8A-8B are section views illustrating penetration limiting mechanisms for use with the
implantation instrument 10. The penetration limiting mechanisms limit the depth of penetration of the incisingshaft 11 and help prevent excessive penetration. FIG. 8A shows a fixed penetration limiting mechanism consisting of a stoppingflange 55 attached to the incisingshaft 11. The position of the stoppingflange 55 along the incisingshaft 11 can be adjusted by loosening a hold-down screw 58 and sliding the stoppingflange 55 into the desired location. The lower edge of the stoppingflange 55 has abend 57 with an angle τ, preferably between approximately 30° and 60°, thereby forming anelbow 56 which stops lateral travel upon contact with the skin. - FIG. 8B shows an adjustable penetration limiting mechanism consisting of a stopping flange60 attached a
frictional collar 64. The stopping flange 60 andfrictional collar 64 are slidably attached to the incisingshaft 11. Anadjustable collar 64, preferably in threadedcommunication 65 with thefrictional collar 64, manually stops deployment of the penetration limiting mechanism by tightening thefrictional collar 64 against the incisingshaft 11. The lower edge of the stopping flange 60 has abend 62 with an angle, preferably between approximately 30° and 60°, thereby forming anelbow 61 which stops lateral travel upon contact with the skin. - FIG. 9 is a perspective view of an instrument for implanting sensors or solid materials in a subcutaneous or other tissue location in accordance with a further embodiment of the present invention. The instrument is equipped with the stopping
flange 55 shown in FIG. 8A. Other forms of penetration limiting mechanisms, both fixed and adjustable, could be used, as would be readily apparent to one skilled in the art. - While the invention has been particularly shown and described as referenced to the embodiments thereof, those skilled in the art will understand that the foregoing and other changes in form and detail may be made therein without departing from the spirit and scope of the invention.
