BACKGROU~-D OF l~[E INVE~TTION
1. Field of the Invention This invention relates to a device for delivering material to a remote location and more particularly, to an instrument for endoscopic delivery of a quantity of medicament or material to a remote location within the body.
. Description of the Reiated Art In laparoscopic procedures, surgery is performed through a small incision or entrance wound in the skin with the abdominal cavity expanded by gas15 insuMation. Laparoscopic procedures generally require that any instrumentation inserted into the body be sealed so that gases do not enter or exit the body through the incision. Further, laparoscopic procedures often require the surgeon to operate on organs or tissues which ale far removed from the incision"hereby requiring that any instruments to be used in such procedures be both elongated and narrow.
In open surgery, hemostasis is achieved by using agents such as collagen and cellulose in either a pre-formed pad or a loose powdered forrn. These hemostatic agents are applied to sites of hemorrhage or bleeding intraoperatively and, due to their thromboplastic nature, cause cessation or reduction of bleeding. A
hemostatic collagen paste which may be used in this manner is disclosed in U.S.
Patent No. 4,891,359 to Saferstein et al. These materials are easily applied by hand during open surgery because the site of intended application is readily accessible.
The use of hemostatic agents and other medicaments in laparoscopic 30 surgery poses unique problems due to the limited access to the site of application and 2~ ~31 8 the difficulty of passing material to the site via a cannula or trocar. During laparoscopic procedures, materials, such as adhesion barriers, have been de}ivered to an intended site of application by grasping the material with a micrograsper or othe~
s similar instrument, and extending the instrument throuoh a cannula placed in an incision or entrance wound. However, it would be difficult to repetitively deliver a metered quantity of fluid or powdered material in such a manner. Once the material has been introduced into the abdominal cavity, post-insertion manipulation of the 10 material is also extremely difficult.
In addition, because of the difficulty and expense of cleaning and sterilizing surgical instruments between uses, there is an increasing demand forinstruments which are disposable after use in a single surgical procedure rather than permanent and reusable. Additionally, instrumentation which re~uires the use of external power supplies is less efficient for clinical applications.
SUMl~IAR~ OF THE INVEI`ITION
An endoscopic device is disclosed for delivering a quantity of material 20 to an organ or tissue area within a body. The device includes an endoscopic portion having a passageway formed therein, material containment means communicating u~ith said passageway and actuating means for causing the delivery of a quantity of material from the material containment means. The device may further include separate 25 propellant containment me~ns for dispensing powder or particulate medicaments.
Alternatively, the material containment means may also contain a propellant. Thematerial containment me~ns may comprise a reservoir integrally formed in the endoscopic portion or in a handle portion. Preferably, the cont~inment means 30 comprises a removable cartridge.
2 ~
The actuating means may be pivotal and may include a trigger. A
plunger means operatively connected to the trigger may also be included for advancing distally against the containment means in such a manner as to cause a predetermined quantity of medicament to be expelled from the containment means such as, for example by a propellant.
In another aspect the present invention, the material for deliver,Y to the intended site of application is disposed in the axial passageway of the endoscopic 10 portion of the delivery device. In this instance, the material may comprise a pre-formed hemostatic treatment pad or in the alternative the material may comprise a fluid or powdered medicament. Actuating means are operatively connected to the endoscopic portion for causing a predetermined quantity of the material to be delivered from the endoscopic portion.
15In yet another aspect of the present invention, the delivery device is provided with tamp;ng means for manipulating the material delivered.
Further features of the invention will become more apparent from the accompanying drawings and the following detailed description of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBOD~IENTS
A preferred embodiment of the endoscopic material delivery device of the subject invention is illustrated in Figs. 1 and 2 and is designatecl generally by reference numeral 10~ The delivery device 1~ includes a pistol-like handle portion having a longitudinal barrel portion 12 w;th a grip portion 14 depending transversely from the barrel portion 12. Portion 14 may be generally rec~angular in cross-section as shown or may have any configuration which may be easily and comfortably gripped during operations~ ~3arrel portion 12 includes a cover 16 which is at~ached thereto by an integral hinge 18 located at the proximal end 20 of the barrel portion 12~ A port 22 is formed in the distal end 24 of barrel portion 12 for receiving an elongated disposable endoscopic shaft 26. More particularly, a tapered proximal end 28 of endoscopic shaft 26 may be inserted through the port 22 formed in barrel portion 12 so as to be frictionally or mechanically engaged therein for operations~
The endoscopic shaft 26 is formed with an axial passageway 30 through which a 2 ~ 3 metered quantity of material may be delivered to the intended site of application, for e.~ample, within ~he abdominal cavity.
The delivery device 10 further includes a movable trigger 32 which 5 depends transversely from ba~el portion l~ adjacent portion 14. In particular, trigger 32 is mechanically linlced to a piston mechanism 34 disposed in the barrel portion 1~.
Piston mechanism 34 includes a circular plunger 36 depending from a shaft 38 which is slidably maintained in a sleeve 40. The trigger 3~ is ope~rative to cause shaft 38 to 10 slide within sleeve 40 so that plunger 36 may be moved into contact with the rear end 4~ of containment me~ns 44, here shown as a replaceable cylindrical containment cartridge. It should be understood that the containment means 44 may alternatively be a reservoir iniegrally formed within the barrel 12.
Cartridge 44 which may contain a propellent and/or a powdered or 5 fluid medicament, is maintained in barrel portion 12 on a pair of space~i apart support flanges 46 and 48 disposed adjacent the distal end 24 of barrel portion 12.
Furthermore, cartridge 44 may be formed with a penetrable membrane 50 disposed at the front end 52 thereof. The membrane 50 is easily pierced by the tapered end 28 of 20 the endoscopic shaft 26 uyon extending the shaft 26 through the port 22.
While described in terms of delivering a medicament, the device of the present invention can be used to deliver a wide variety of fluid, powdered or solid materials. Such materials include, but are not limited to pharmaceuticals, materials 25 having anti-adhesion properties, anti-coagu~ants, growth factors, osteogenic factors, antibiotics, anti-fungals, immunosuppressive agents, anti-inflammatory agents, irrigating fluids, disinfectants, preservatives, diagnostic agents (dyes, etc.) antihistam;nes, hormones, enzymes, peptides and/or steroids. Solid materials which may be delivered include woven materials, gels, capsules, molded materials and any 3 :~ ~
other solid form which fits within or may be made to fit within the endoscopic portion of the device~
In operation, a cartridge 44 is placed in support f~anges 46 and 48 in 5 the barrel portion 12 of the delivery device 10 and tl1e cover 16 is closed~
Thereupon, the endoscopic shaft 26 is inserted into port ~2 at end 24 of barrel portion 12. At such a time, the tapered end 28 of endoscopic shaft 26 pierces the membrane 50 at the front end 52 of cartridge 44~ Thereafter, the end 54 of endoscopic shaft 26 10 is inserted through a cannula (not shown) previously inserted in aul incision or entrance wound~ When trigger 32 is depressed, the piston mechanism 34 slides forward and plunger 36 is urged against the rear end 42 of cartridge 44 causing the propellent therein to propel a metered quantity of medicament through the passageway 30 in endoscopic shaft 26 to be delivered into the abdominal cavity~
When cartridge 44 contains a fluid medicament, a first squeeze of the trigger 32 wi]l cause plunger 36 to contact the rear end 42 of cartridge 44~ Upon release of the trigger spring means (not shown) urge the trigger back to its original position. Subsequent squee7es of the trigger 32 will move the plunger 36 a 20 predetermined distance into cartridge 44, thus t`orcing a metered amount of medicament out of cartridge 44 and into the endoscopic portion of the instrument. If the fluid medicament has a high viscosity, a series of squeezes may be required to prime the instrument before the metered amount of medicament is delivered out the 25 dist~ end of the endoscopic portion.
In a variation of this embodiment, the passageway 30 of endoscopic portion 26 serves as the containment means and is pre-loaded with the medicament to be deli~ered. Actuating means may directly cause the material to be expelled from 30 the endoscopic portion or, as shown in the figures, the actuating means may act upon container 44 which contains a non-toxic, inert delivery substance which merely acts to force a metered quantity of the medicament out of the endoscopic portion. That is, as plunger 3S advances within cartridge 41, a metered amount of the deliYery subst~nce is forced out of cartridge 44 and into endoscopic portion ~6, which in turn forces a s metered quantity of the medicament out of the distal end of passageway 30. A series of endoscopic portions each loaded with a different medicament may be provided in a kit thus allowing the same handle portion to deliver each medicament as needed without mixing or contamination of the individual medicaments.
l O Referring to Figs. 3 and 4, another embodiment of the endoscopic material delivery device of the subject invention is illustrated and is designated generally by reference numeral 60. Delivery device 60 includes a handle pGrtion having a longitudinal barrel portion 62 and a hollow grip portion 64 having a generally circular cross-section projecting transversely from barrel portion 62. A
movable trigger 66 depends transversely from barrel portion 6~ adjacent portion 64.
Barrel portion 64 includes a cover 68 integrally attached at the proximal end 70thereof and a port 7~ formed in the proximal end 74 thereof for receiving the tapered end 28 of an endoscopic shaft 26. As stated previously, the tapered end 28 of the 20 endoscopic shaft 26 is provided for piercing the penetrable membrane S0 at the Front end of cartridge 44. The delivery device 60 is further provided wi~h a cap member 76 which is threadably engaged in the bottorn 78 of handle portion 64 and which may be readily removed to insert a canister of compressed gas 80.
Trigger 66 is mechanically lin~ced to the canister of compressed gas 80 in a known manner known, such as that described in U.S. Patent No. 4,349,028, the entire disclosure of which is incorporated herein by reference. In addition, a conduit element 82 in barrel portion 62 is connected to the compressed gas canister 80.
Conduit element 82 conducts compressed gas from the canister 80 to the rear end 42 ~ ~ e~ 3 of replaceable cartridge 4~ which preferably contains a medicament in a powderedform.
In operation, the trigger 66 may be depressed in such a manner as to cause compressed gas to exit canister 80. Thereupon, compressed gas from canister 80 is conducted through conduit element 82 in such a manner as to exert a force upon the rear end 42 of cartridge 44, thereby causing a metered quantity of medicament to be delivered from cartlidge 44 through the endoscopic shaft 26 to the intended site of 1 o application.
Figs. S and 6 depict another embodiment of the endoscopic material delivery device of the subject invention designated generally by reference numeral 90.
The delivery device 90 includes a long;tudinal barrel portion 92 having a proximal end 94, a distal end ~6 and a substantially circular midsection 98. A grip portion lO0 and a trigger 102 project transversely from barrel portion 92. Barrel portion 92 is provided with a cover member 104 and a threaded port 106 formed in the proximal end 94 thereof. A four bar linka~e 10~ is operatively disposed in the circular midsection 98 of barrel portion 92. Linkage 108 includes a generally U-shaped key 110 arranged adjacent the pro:~imal end 94 of barrel portion 92. Linkage 108 is operably connected to trigger 102 which when depressed causes linkage 108 to compress in such a manner that the U-shaped key 1 lû advances distally in barrelportion 92.
An endoscopic member 112 is threadably engageable in port 106 formed in the barrel portion 92. Endoscopic member 112 compnses an elongated tube portion 114 having an axial passageway I 16 in which is disposed plunger member 118. A pre-formed treatment pad 120 or a reservoir of medicament is located in the tube 114 distal to the plunger member 118. More particularly, plunger member 118 includes a shaft portion 122 having a circular portion 124 at the 2 ~
proximal end thereof disposed internal of the tube portion l 14 and a generally U-shaped key 126 formed at the proximal end thereof disposed external of the tube portion 11~. Key l26 on plunger member 118 is engageable with key ll0 on linkage108~
In operation, the endoscopic member 112 may be engaged in the threaded port 106 formed in barrel portion 92 in such a manner so that keys 126 and plunger member 118 are interlocked. Thereupon, trigger 102 may be depressed so as to cause the four bar linkage 108 to compress. At such a time, plunger member 118 is caused to advance proxima~ly in the endoscopic member 112 and force the pre-formed treatment p~d 120 from the axial passageway 116 to the intended area of treatment within the abdominal cavity. Thereafter, the portion 124 follows the pre-formed treatment pad 120 out of the proximal end of the endoscopic member l 12 and protrudes therefrom. The portion 124 may serve as tamping means. Once extended dista~ly from the endoscopic portion the tamping me~uls may then be manipulated to maneuver the pre-formed treatment pad 120 in a desired position or to manipulate any material delivered from the device.
When the tube portion l I4 includes a reservoir of medicament rather than a preformed pad, depressing the trigger 102 advances the plunger member 118distally to urge a metered quantity of the material from the endoscopic member 112 to the intended site of application.
In an altemate embodiment shown in Fig. 7, the tamping portion of the pIunger member 118 may be a frusto-conical shaped portion 128 rather than circular portion I24. Alternatively, portion 124 may be formed with an axial aperture through which medicament stored behind the portion 124 may, upon squeezing the trigger 102, be delivered under pressure.
2 ~
In an alternative embodiment (not shown,) tamping means are disposed in a second passageway formed in the endoscopic yortion, and actuating means similar to that described above for delivering material, may be used to deploy the s tamping means. The tamping means itself may advantageously be fabricated from an elastic material, such as a synthetic or natural rubber or a shape memory alloy, such as for examyle the alloys described in U.S. Patent No. 4,665,906 the disclosure of which is incorporated herein by reference. In a particularly useful embodiment the 1~ elastic tamping means ;s disposed in the second passageway in a deformed state and assumes a substantially undeformed state when deployed out of the passageway to facilitate manipulation of the material just delivered.
Although the invention has been described with reference to preferre~
embodiments it is apparent that several changes may be made without departing from the spirit and scope of the subject invention.
For example, it may be readily appreciated that the endoscopic portion may be formed integrally with the barrel portion of the device. In this instance the entire device may be disposable. Furthermore, the trigger portion may be disposed 20 substantially parallel to the longitudinal axis of the barrel portion for providing a palm-grip arrangement.
In addition, a separate propellant containment means and medicament containment means may be provided rather than having a combined propellant and 25 medicament cartridge element. In this instance, the barrel portion of the device may be provided with means for supporting and/or interconnecting both cartridges.
Furthermore, it may be readily appreciated that the barrel portion of the device may be forrned with an integral reservoir within which medicament is 30 stored for delivery. When the medicament is in a powdered form, it may be 2~:131~
propelled from the reservoir by a compressed gas supply stored in the handle portion of the device.

Conduit element 82 conducts compressed gas from the canister 80 to the rear end 42 ~ ~ e~ 3 of replaceable cartridge 4~ which preferably contains a medicament in a powderedform.
In operation, the trigger 66 may be depressed in such a manner as to cause compressed gas to exit canister 80. Thereupon, compressed gas from canister 80 is conducted through conduit element 82 in such a manner as to exert a force upon the rear end 42 of cartridge 44, thereby causing a metered quantity of medicament to be delivered from cartlidge 44 through the endoscopic shaft 26 to the intended site of 1 o application.
Figs. S and 6 depict another embodiment of the endoscopic material delivery device of the subject invention designated generally by reference numeral 90.
The delivery device 90 includes a long;tudinal barrel portion 92 having a proximal end 94, a distal end ~6 and a substantially circular midsection 98. A grip portion lO0 and a trigger 102 project transversely from barrel portion 92. Barrel portion 92 is provided with a cover member 104 and a threaded port 106 formed in the proximal end 94 thereof. A four bar linka~e 10~ is operatively disposed in the circular midsection 98 of barrel portion 92. Linkage 108 includes a generally U-shaped key 110 arranged adjacent the pro:~imal end 94 of barrel portion 92. Linkage 108 is operably connected to trigger 102 which when depressed causes linkage 108 to compress in such a manner that the U-shaped key 1 lû advances distally in barrelportion 92.
An endoscopic member 112 is threadably engageable in port 106 formed in the barrel portion 92. Endoscopic member 112 compnses an elongated tube portion 114 having an axial passageway I 16 in which is disposed plunger member 118. A pre-formed treatment pad 120 or a reservoir of medicament is located in the tube 114 distal to the plunger member 118. More particularly, plunger member 118 includes a shaft portion 122 having a circular portion 124 at the 2 ~
proximal end thereof disposed internal of the tube portion l 14 and a generally U-shaped key 126 formed at the proximal end thereof disposed external of the tube portion 11~. Key l26 on plunger member 118 is engageable with key ll0 on linkage108~
In operation, the endoscopic member 112 may be engaged in the threaded port 106 formed in barrel portion 92 in such a manner so that keys 126 and plunger member 118 are interlocked. Thereupon, trigger 102 may be depressed so as to cause the four bar linkage 108 to compress. At such a time, plunger member 118 is caused to advance proxima~ly in the endoscopic member 112 and force the pre-formed treatment p~d 120 from the axial passageway 116 to the intended area of treatment within the abdominal cavity. Thereafter, the portion 124 follows the pre-formed treatment pad 120 out of the proximal end of the endoscopic member l 12 and protrudes therefrom. The portion 124 may serve as tamping means. Once extended dista~ly from the endoscopic portion the tamping me~uls may then be manipulated to maneuver the pre-formed treatment pad 120 in a desired position or to manipulate any material delivered from the device.
When the tube portion l I4 includes a reservoir of medicament rather than a preformed pad, depressing the trigger 102 advances the plunger member 118distally to urge a metered quantity of the material from the endoscopic member 112 to the intended site of application.
In an altemate embodiment shown in Fig. 7, the tamping portion of the pIunger member 118 may be a frusto-conical shaped portion 128 rather than circular portion I24. Alternatively, portion 124 may be formed with an axial aperture through which medicament stored behind the portion 124 may, upon squeezing the trigger 102, be delivered under pressure.
2 ~
In an alternative embodiment (not shown,) tamping means are disposed in a second passageway formed in the endoscopic yortion, and actuating means similar to that described above for delivering material, may be used to deploy the s tamping means. The tamping means itself may advantageously be fabricated from an elastic material, such as a synthetic or natural rubber or a shape memory alloy, such as for examyle the alloys described in U.S. Patent No. 4,665,906 the disclosure of which is incorporated herein by reference. In a particularly useful embodiment the 1~ elastic tamping means ;s disposed in the second passageway in a deformed state and assumes a substantially undeformed state when deployed out of the passageway to facilitate manipulation of the material just delivered.
Although the invention has been described with reference to preferre~
embodiments it is apparent that several changes may be made without departing from the spirit and scope of the subject invention.
For example, it may be readily appreciated that the endoscopic portion may be formed integrally with the barrel portion of the device. In this instance the entire device may be disposable. Furthermore, the trigger portion may be disposed 20 substantially parallel to the longitudinal axis of the barrel portion for providing a palm-grip arrangement.
In addition, a separate propellant containment means and medicament containment means may be provided rather than having a combined propellant and 25 medicament cartridge element. In this instance, the barrel portion of the device may be provided with means for supporting and/or interconnecting both cartridges.
Furthermore, it may be readily appreciated that the barrel portion of the device may be forrned with an integral reservoir within which medicament is 30 stored for delivery. When the medicament is in a powdered form, it may be 2~:131~
propelled from the reservoir by a compressed gas supply stored in the handle portion of the device.
