Abstract

Intercutaneous implant devices useful in intraluminal and extraluminal procedures for externalization of vessels are provided which have a hollow cylinder with an upper and lower end and an interior and exterior surface, said hollow cylinder having a central aperture which is greater in diameter than the exterior expanse of the access site and a length which provides for adequate annular separation of the externalized vessel at the exterior and interior surface of the implant to ensure adequate blood supply to the vessel; a flange extending from the upper end of the hollow cylinder which provides a platform onto which is attached a termination device; and a plane contacting surface extending from the lower end of the hollow cylinder which provides a means for fixation of the implant to the patient.

Claims

1. An intercutaneous implant device for externalization of vessels comprising:

(a) a hollow cylinder having an upper and lower end and an interior and exterior surface, said hollow cylinder having a central aperture which is greater in diameter than the exterior expanse of an access site thereby providing a space between the access site and the central aperture and a length which provides for adequate annular separation of an externalized vessel at the exterior and interior surface of the implant to ensure adequate blood supply to the vessel and to the adjacent tissue;

(b) a flange extending from the upper end of the hollow cylinder which provides a platform onto which is attached a termination device; and

(c) a plane contacting surface extending from the lower end of the hollow cylinder which provides a means for fixation of the implant to the patient.

2. The intercutaneous implant device of claim 1 wherein the exterior surface of the hollow cylinder is covered with a textile surface layer comprised of a porous polymer.

3. The intercutaneous implant device of claim 1 further comprising a textile ring or a plurality of textile fixtures extending perpendicularly from the plane contacting surface of the implant.

4. The intercutaneous implant device of claim 3 further comprising a plurality of textile rings extending perpendicularly from the hollow cylinder of the implant.

5. The intercutaneous implant device of claim 1 wherein the hollow cylinder is rigid.

6. The intercutaneous implant device of claim 1 wherein the hollow cylinder is flexible and capable of changing diameter upon extension and distension of the vessel.

7. The intercutaneous implant device of claim 1 wherein the hollow cylinder is formed as a helical screw and the plane contacting surface is formed by a plurality of cutting edges which terminate as concurrent threads of the helical screw.

8. The implant device of claim 1 wherein the hollow cylinder is formed with a helical screw and the plane contacting surface is formed by a plurality of cutting edges which terminate in concurrent threads of said helical screw.
