- FIGS. 10 and 11 show a modification of the construction of FIG. 9 with its operational features emphasized.
- FIG. 1 The presently preferred embodiment of an artery-tovein shunt 20 is shown assembled in FIG. 1. It is intended surgically to be implanted relative to the skin with part of it beneath the skin and part of it above the I 26. While these buttons may take a number of shapes,
- the presently preferred form is ovular, i.e., relatively elliptical in plan view (FIG. 6). It has been found that generally elongated form such as this enables the button to be planted in the skin in a relative long slit and be accommodated thereby better than when a circular or other shape is used instead, especially in the arm or leg.
- the buttons are identical, and only button 25 will be described in detail.
- the body member 25a is preferably flat with a top surface 27 and a bottom surface 28, the terms top and bottom referring to outside and inside the skin level in which the button is-placed.
- a peripheral wall 29 extends around the body and interconnects the top and bottom surfaces.
- a peripheral groove 30, which may have a relatively sharp apex 31, extends peripherally around the wall. The skin 23 of the patient will have been cut, and the edges of the cut will be received in the peripheral groove in a manner yet to be described.
- a first and second shunt tube 35 and 36 are respectively attached to and pass through the first and second buttons.
- the constructions of the first and second shunt tubes are identical, except that they are mirror images, so that only shunt tube 35 will be described in detail.
- Shunt tube 35 has an inner wall 37, an outer wall 38, and a flow conduit 39 passing therethrough.
- the first and second shunt tubes respectively include coupler portions 40, 41 which are positioned on the outside of the device when installed, i.e., above the top surface. They also include respective connector portions 42, 43 which extend from the bottom wall and are v intended for long-term attachment to a respective vein 22 or artery 21. First and second shunt tubes 35 and 36 have free ends 46, 47 on the connector portions and free ends 48, 49 on the coupler portions at the end thereof.
- a flexible and resilient coil spring 55 is formed between the inner and outer walls of each of the connector portions adjacent to the free ends thereof-This spring may readily be molded into the material of the connector portion at the time it is made. It provides springy support to maintain the circular shape of the tubes at the point of attachment to the artery or vein.
- a fixation cuff 60, 61 is attached to the shunt tube adjacent to the respective free ends of 46 and 47 of the connector portions. They are made of a material yet to be described, and can be cemented or sewed into place on the outer wall of the respective conductor portion.
- I Shunt tube stabilizer means 65 (FIG. is attached to and extends peripherally around the outer wall of the connector portions of the first and second shunt tubes adjacent to the bottom surface of the respective button. It extends axially along the connector portion as shown.
- the shunt tube stabilizer means may further include said material applied as a layer 66 to the said bottom surface of the respective button for purposes yet to be described.
- a third shunt tube 70 is generally U-shaped and has a flow conduit 71 and a pair of free ends 72, 73 respectively adapted to make a fluid-tight connection with the free ends 48 and 49 of the coupler portions.
- Couplings 75, 76 are provided, one for joining each shunt tubes. These couplings include shoulders 77, 78
- Clamp 81 is identical to it.
- Clamp 82 has a central channel 83 to pass the connector portion and the third shunt and to receive their free ends. It also includes a pair of shoulders 84, 85 on the clamp which can be brought to bear against shoulders 78 and 80 so as to hold the free ends together in a compressive fit.
- the material of the clamp may be inherently springy such that it can be snapped into place and will retain itself under those circumstances. It can also readily be removed by reverse motion..
- Peripheral button-sealing means are attached to the inside wall 91 of peripheral groove 30.
- the purpose of this material is to form a fluid seal and a stop for infection at the point of entry of the shunt system. Materials suitable for this button-sealing means will be described below.
- Seal means 95 may be provided to seal the assembled three shunt tubes against leakage at the free ends of the coupler portions.
- relatively complicated conventional fluid-seals such as O-rings and the like could be used, when relatively resilient materials such as polyethylene or medical grade silicone rubber (silicon elastomer) is used as a material of construction, a satisfactory fluid seal can be obtained by direct surface-to-surface abutting fit.
- the seal means 95 comprises peripheral end surfaces 96, 97 on the coupler portion 41 and on the third shunt tube 70, respectively. These surfaces are flat annuli and are brought together against one another at the time the clamp is applied.
- the sealing action can be improved by the means shown in FIGS. 10 and 11 wherein, instead of forming end surfaces 96 and 97 both as inherently deformable flat surfaces, end surface 96 is formed rounded.
- the material of which the fixation cuffs 60 and 61, the shunt tube stabilization means 65, and the peripheral button-sealing means 90 can be made is a material with openings into which tissue can penetrate, and which is not harmful to or absorbed by body tissue.
- a material is necessary for the fixation cuffs and shunt tube stabilizer means, but the button-sealing means may, instead, merely use compatible resilient material, such as a compressible open or closed cell silicon elastomer foam or sponge if desired.
- compatible resilient material such as a compressible open or closed cell silicon elastomer foam or sponge if desired.
- the preferred material is a woven dacron mesh, preferably in the form of a velour. This cloth construction forms a group of openings into which tissue can penetrate.
- tissue is not deleterious to the surrounding tissue, and, after a period of implantation, it will be noted that tissue has grown into this material to hold it in place, and as to the bottom-sealing means, prevents leakage of fluid past it and also provides a bar to the penetration of organismswhich might prove to be a source of infection.
- the coupler portions and the connector portions lie primarily in planes which are spaced apart from one another on opposite sides of the buttons, and the planes lie substantially parallel to the plane of the peripheral groove in the button which is, of course, the plane of the skin in which the button is implanted.
- the first and second shunt tubes are mirror images of each other, and the free ends of their connector portions are generally parallel to one another.
- the connector portions may be made U-shaped more conveniently to be connected to the artery or vein.
- the material of which the shunt tubes are made is preferably slightly resilient, but stiff enough to be shape-retentive.
- Polyethylene is a suitable material of construction, as is medical grade silicone rubber (silicon elastomer).
- the third shunt tube should be made of readily cuttable material, such as a realtively softer polyethylene, in order that it may receive an adapter 110.
- the third shunt tube When the device is implanted in the patient, and the patient is not connected to a dialysis machine, the third shunt tube will be in place as shown in FIG. 1, and flow will be directly from the artery to the vein. The bypassed regions' of the body downstream of the artery will be supplied by peripheral circulation.
- a single cut 112 may be made, and identical adapters 113, 114 are plugged into the stub ends 115, 116 of the U-shaped third shunt tube. This arrangement is shown in FIG. 3.
- FIG. 7 is shown a situation where two cuts are made in the third shunt tube, and the bight 117 of the third shunt tube is discarded.
- FIG. 4 illustrates the means of implanting the connector portion in the human body. It is, of course, a surgical technique.
- artery 22 (or vein 21) is cut off to a square face 120 which is brought against the free end of the connector portion of the first shunt tube. Then it is sutured by sutures 121, 122 in accordance with known surgical techniques.
- the sutures preferably pass through the fixation cuff, andthe fixation cuff extends tubularly over the end of the vein or artery. If desired, the suture may also be looped 1 through one of the convolutions of the coil spring, but
- the shunt tube stabilizer means i.e., that portion which extends along the connector portion next to the button and, when used on the bottom surface of the button, also there, will enable tissue ingrowth to occur which will stabilize the button relative to the skin and surrounding structure;
- the buttonsealing means will prevent the leakage of the fluid and will also further tend to stabilize the button, particularly against turning, although the non-circular construction of the button will in itself aid in resisting that motion.
- an artery-to-vein shunt which can be implanted for long-term use in the human body and which can be worn without discomfort.
- a cut or cuts is or are made in the U-shaped third shunt tube, and the stub ends are connected at the dialysis machine.
- the U-shaped third shunt tube is replaced. Each time there is used and thrown away only an inexpensive U-shaped piece of plastic.
- the dimensions of the device are arbitrary, and will be suited to the flow rates and intended locations of imof the conduits is l/8 inch, and the button is about 1/2 inch by 3/16 inch in its major and minor dimension. The button is about 3/16 inch thick.
