Abstract

An implant device including a tube for connection at one end thereof to a blood vessel under the skin of a patient, with an opposite end of the tube projecting through the skin, and a valve at the opposite end of the tube for selectively blocking and passing blood. The tube is preferably affixed to the skin with fastening means. One embodiment of the tube is an elbow, and another embodiment has a T configuration.

Claims

1. An implant device comprising a tube means for connection to a blood vessel of a patient, fastening means for affixing an intermediate portion of said tube means to the skin of the patient to retain one end of said tube means connected to the blood vessel in the flesh under the skin of the patient with the opposite end of said tube means projecting through the skin to the outside thereof, and valve means affixed at said opposite end of said tube means for selectively blocking and passing flow of blood from said vessel through said tube means.

2. The implant device as claimed in claim 1 in which said tube means is in the form of an elbow.

3. The implant device as claimed in claim 1 in which said tube means has a third end for connection to a blood vessel under the skin.

4. The implant device as claimed in claim 3 in which said tube means has a T configuration.

5. The implant device as claimed in claim 1 in which said valve means comprises a puncturable membrane.

6. The implant device as claimed in claim 1 in which said valve means comprises a disc having apertures at the periphery thereof, and said tube means has a shoulder receiving the apertured periphery of said disc for closing said apertures, and means biasing said disc toward said shoulder.

7. The implant device as claimed in claim 1 in which said fastening means includes a first plate affixed to said tube means, a econd plate having an aperture to receive said tube means, porous pad means for interposition between said plates, and means for fastening said plates together on opposite sides of the skin with said pad means contacting the skin.

8. The implant device as claimed in claim 1 in which said tube means has a detachable section at said oPposite end in which said valve means is affixed.

9. The implant device as claimed in claim 8 in which said detachable section includes a removable cap for closing said opposite end.

10. An implant device comprising tube means for connection at one end thereof to a blood vessel under the skin of a patient with the opposite end thereof projecting through the skin, and valve means at said opposite end for selectively blocking and passing flow of blood from said vessel through said tube means.

11. The implant device as claimed in claim 10 in which said tube means is in the form of an elbow.

12. The implant device as claimed in claim 10 in which said tube means has a third end for connection to a blood vessel under the skin.

13. The implant device as claimed in claim 12 in which said tube means has a T configuration.

14. The implant device as claimed in claim 10 in which said valve means comprises a puncturable membrane.

15. The implant device as claimed in claim 10 in which said valve means comprises a disc having apertures at the periphery thereof, and said tube means has a shoulder receiving the apertured periphery of said disc for closing said apertures, and means biasing said disc toward said shoulder.

16. The implant device as claimed in claim 10 in which said tube means has a detachable section at said opposite end in which said valve means is affixed.

17. The implant device as claimed in claim 16 in which said detachable section includes a removable cap for closing said opposite end.

18. The implant device as claimed in claim 10 including clamping means for clamping said one end of said tube means to the blood vessel.
