Abstract

Heterogeneous yarns containing strands of dissimilar materials are useful in forming surgical device.

Claims

1. A surgical device comprising:

at least one heterogeneous yarn including a plurality of polyester strands in intimate contact with a plurality of polyolefin strands.

2. A surgical device as in claim 1, wherein the polyester strands comprise polyethylene terephthalate.

3. A surgical device as in claim 1, wherein the polyolefin strands comprise polyethylene.

4. A surgical device as in claim 1, wherein the polyolefin strands comprise ultra high molecular weight polyethylene.

5. A surgical device as in claim 1, wherein the at least one heterogeneous yarn further includes strands made from a material other than polyolefin or polyester.

6. A surgical device as in claim 1, wherein the polyester strands and polyolefin strands are twisted together to form the heterogeneous yarn.

7. A surgical device as in claim 1, comprising a plurality of heterogeneous yarns that are braided.

8. A surgical device as in claim 1, comprising plurality of heterogeneous yarns that are knitted.

9. A surgical device as in claim 1, comprising a plurality of heterogeneous yarns that are woven.

10. A biocompatible surgical device comprising a textile prepared from a plurality of heterogeneous yarns having strands of polyethylene terephthalate in intimate contact with strands of ultra high molecular weight polyethylene.

11. A biocompatible surgical device as in claim 10, wherein the textile comprises braided heterogeneous yarns.

12. A biocompatible surgical device as in claim 10, wherein the textile comprises knitted heterogeneous yarns.

13. A biocompatible surgical device as in claim 10, wherein the textile comprises woven heterogeneous yarns.

14. A biocompatible surgical device as in claim 10, wherein the textile is adapted for use as a device selected from the group consisting of sutures, tapes, gauze, wound dressings, hernial repair meshes, vascular grafts, anastomosis rings, prosthetic ligaments, prosthetic tendons, growth matrices and drug delivery devices.

15. A biocompatible surgical device as in claim 14, wherein the textile is a braided suture.

16. A suture comprising at least one heterogeneous yarn having polyester strands in intimate contact with polyolefin strands.

17. A suture as in claim 16, wherein the polyester strands comprise polyethylene terephthalate.

18. A suture as in claim 16, wherein the polyolefin strands comprise polyethylene.

19. A suture as in claim 16, wherein the polyolefin strands comprise ultra high molecular weight polyethylene.

20. A suture as in claim 16, wherein the heterogeneous yarn is coated with a composition containing one or more biologically active materials.
