Abstract

A vascular prosthesis is described, having blunted wire ends. The blunted wire ends can take on a variety of configurations including end caps, bent ends, curved ends, or eyelets. The novel ends provide a smooth surface to contact the blood vessel walls thereby reducing the risk of trauma during placement of the prosthesis.

First claim

What is claimed is:

1 . A vascular prosthesis comprising:
a plurality of wires woven together to form a tubular shape, each of the plurality of wires having terminal ends; at least some of the terminal ends of the each of the plurality of wires being terminated with a cap having a cylindrical body and a rounded distal end; the cap comprising a trimmed first terminal end, a trimmed second terminal end, and a metal tube positioned flush over and melted together with the trimmed first terminal end and the trimmed second terminal end.

2 . The vascular prosthesis of claim 1 , wherein the terminal ends of the plurality of wires are located at each end of the tubular shape.

3 . The vascular prosthesis of claim 1 , wherein the trimmed first terminal end and the trimmed second terminal end form a triangular or pointed shape.

4 . The vascular prosthesis of claim 1 , the trimmed first terminal end and the trimmed second terminal end form a loop.

5 . The vascular prosthesis of claim 1 , wherein the cap is formed of nitinol or tantalum.

6 . The vascular prosthesis of claim 1 , wherein the vascular prosthesis comprises an outer layer and an inner layer.

7 . A vascular prosthesis comprising:
a plurality of wires woven together to form a tubular shape; and, a plurality of caps located at one or more ends of the tubular shape; each of the plurality of caps having a cylindrical body and a rounded distal end; and each of the plurality of caps comprising a trimmed first wire end of one of the plurality of wires, a trimmed second wire end of one of the plurality of wires, and a metal tube positioned flush over and melted together with the trimmed first wire end and the trimmed second wire end.

8 . The vascular prosthesis of claim 7 , wherein the plurality of caps is located at proximal and distal ends of the tubular shape.

9 . The vascular prosthesis of claim 7 , wherein the trimmed first wire end and the trimmed second wire end form a triangular or pointed shape.

10 . The vascular prosthesis of claim 7 , the trimmed first wire end and the trimmed second wire end form a loop.

11 . The vascular prosthesis of claim 7 , wherein the cap is formed of nitinol or tantalum.

12 . The vascular prosthesis of claim 1 , wherein the vascular prosthesis comprises an outer layer and an inner layer.

13 . A vascular prosthesis comprising:
a plurality of wires woven together to form a tubular shape; and, a plurality of caps each terminating two of the plurality of wires; each of the plurality of caps having a cylindrical body and a rounded distal end; and each of the plurality of caps comprising a trimmed first wire end of one of the plurality of wires, a trimmed second wire end of one of the plurality of wires, and a metal tube positioned flush over and melted together with the trimmed first wire end and the trimmed second wire end.

14 . The vascular prosthesis of claim 13 , wherein the plurality of caps is located at proximal and distal ends of the tubular shape.

15 . The vascular prosthesis of claim 13 , wherein the trimmed first wire end and the trimmed second wire end form a triangular or pointed shape.

16 . The vascular prosthesis of claim 13 , the trimmed first wire end and the trimmed second wire end form a loop.

17 . The vascular prosthesis of claim 13 , wherein the cap is formed of nitinol or tantalum.

18 . The vascular prosthesis of claim 13 , wherein the vascular prosthesis comprises an outer layer and an inner layer.
