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.

Claims (23)

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; and,

wherein the trimmed first terminal end and the trimmed second terminal end contact each other and terminate within the cap.

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. The vascular prosthesis of claim 1 , wherein the trimmed first terminal wire end is parallel to and adjacent with the trimmed second terminal wire end within the metal tube.

8. 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 terminal wire end of one of the plurality of wires, a trimmed second terminal wire end of one of the plurality of wires, and a metal tube positioned flush over and melted together with the trimmed first terminal wire end and the trimmed second terminal wire end, and wherein the trimmed first terminal wire end and the trimmed second terminal wire end contact each other and terminate within the cap.

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

10. The vascular prosthesis of claim 8 , wherein the trimmed first terminal wire end and the trimmed second terminal wire end form a triangular or pointed shape.

11. The vascular prosthesis of claim 8 , the trimmed first terminal wire end and the trimmed second terminal wire end form a loop.

12. The vascular prosthesis of claim 8 , wherein each of the caps is formed of nitinol or tantalum.

13. The vascular prosthesis of claim 8 , wherein the vascular prosthesis comprises an outer layer and an inner layer.

14. 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 terminal wire end of one of the plurality of wires, a trimmed second terminal wire end of one of the plurality of wires, and a metal tube positioned flush over and melted together with the trimmed first terminal wire end and the trimmed second terminal wire end, and wherein the trimmed first terminal wire end and the trimmed second terminal wire end contact each other and terminate within the cap.

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

16. The vascular prosthesis of claim 14 , wherein the trimmed first terminal wire end and the trimmed second terminal wire end form a triangular or pointed shape.

17. The vascular prosthesis of claim 14 , the trimmed first terminal wire end and the trimmed second terminal wire end form a loop.

18. The vascular prosthesis of claim 14 , wherein each of the caps is formed of nitinol or tantalum.

19. The vascular prosthesis of claim 14 , wherein the vascular prosthesis comprises an outer layer and an inner layer.
