Vessel prosthesis
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.
1. A vascular prosthesis comprising:
a plurality of wires woven together to form a tubular shape with a plurality of loops on an end of the tubular shape;
each of said plurality of loops terminating with a cap having a cylindrical body and a rounded distal end; said cap comprising a trimmed first wire end, a trimmed second wire end, and a metal tube positioned flush over and melted together with said trimmed first wire end and said trimmed second wire end.
2. The vascular prosthesis of claim 1 , wherein the plurality of loops are on each end of the tubular shape.
3. The vascular prosthesis of claim 1 , wherein the plurality of loops are arranged in an alternating pattern of longer loops and shorter loops.
4. The vascular prosthesis of claim 1 , wherein each of the plurality of loops are triangular.
5. The vascular prosthesis of claim 1 , wherein each of the plurality of loops are formed from a first wire having the trimmed first wire end and a second wire having the trimmed second wire end.
6. The vascular prosthesis of claim 1 , wherein the cap is formed of nitinol or tantalum.
7. The vascular prosthesis of claim 1 , wherein the vascular prosthesis comprises an outer layer and an inner layer.
