Abstract

An implant device having a passageway, an anchor for establishing a biological anchor and a grafting mesh annularly disposed about, and spaced apart from, the exterior of the implant device. The implant device passageway, anchor means, and grafting mesh are all formed from either pyrolytic carbon disposed on a graphite substrate or vitreous carbon.

Claims

1. An implant device comprising:

a passageway having an anchor means, both of which are formed from a material selected from the group consisting of (1) pyrolytic carbon disposed on a graphite substrate of (2) vitreous carbon, for attachment to an opened vessel;

said anchor means for establishing a biological anchor;

a grafting mesh annularly and longitudinally disposed about at least a portion of the exterior of said implant device, said grafting mesh being formed from a material selected from the group consisting of (1) pyrolytic carbon disposed on a graphite substrate or (2) vitreous carbon; and

3. The implant device claimed in claim 1 wherein the exterior of said implant device is roughened in order to provide a plurality of interstices in order to facilitate tissue coaption.

4. The implant device claimed in claim 1 wherein an annular rim is positioned about said passageway thereby forming an annular recess between said annular rim and said anchor means.

5. The implant device claimed in claim 1 wherein at least a portion of the exterior of said implant device is coated with collagen.

6. The implant device claimed in claim 1 wherein at least a portion of said grafting mesh is coated with collagen.

8. The implant device claimed in claim 6 wherein said grafting mesh and at least a portion of the exterior of said implant device are coated with collagen.

2. means for radially and longitudinally spacing said grafting mesh away from the exterior of said implant device such that tissue is permitted to grow between the exterior of said implant device and said mesh longitudinally on both sides of said space means.

7. An implant device comprising:

a passageway having an anchor means, both of which are formed from a material selected from the group consisting of (1) pyrolytic carbon disposed on a graphite substrate or (2) vitreous carbon, for attachment to an opened vessel;

said anchor means for establishing a biological anchor, and the exterior of said implant device being roughened in order to provide improved coaption;

an annular rim is positioned about said passageway thereby forming an annular recess between said annular rim and said anchor means;

a grafting mesh annularly and longitudinally disposed about at least a portion of the exterior of said implant device, said grafting mesh being formed from a material collected from the group consisting of (1) pyrolytic carbon disposed on a graphite substrate or (2) vitreous carbon; and

means for radially and longitudinally spacing said grafting mesh away from the exterior of said implant device such that tissue is permitted to grow between the exterior of said implant device and said mesh longitudinally on both sides of said space means.
