Abstract

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

Claims

1. A surgical device comprising:

at least one heterogeneous yarn defining a longitudinal axis and including a plurality of linear disposed polyester strands in intimate contact with a plurality of linear disposed polyolefin strands, wherein the plurality of polyester strands and the plurality of the polyolefin strands run parallel to each other and the longitudinal axis along the length of the yarn.

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, comprising a plurality of heterogeneous yarns that are braided.

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

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

20. A surgical device as in claim 1, wherein the plurality of polyester strands and polyolefin strands are grouped together forming a plurality of interstices that run parallel to each other and the polyester and polyolefin strands along the length of the yarn.

9. A biocompatible surgical device comprising a textile prepared from a plurality of heterogeneous yarns each defining a longitudinal axis and having linear disposed strands of polyethylene terephthalate in intimate contact with linear disposed strands of ultra high molecular weight polyethylene, wherein the plurality of polyethylene terephthalate strands and the plurality of the ultra high molecular weight polyethylene strands run parallel to each other and the longitudinal axis along the length of the yarn.

10. A biocompatible surgical device as in claim 9, wherein the textile comprises braided heterogeneous yarns.

11. A biocompatible surgical device as in claim 9, wherein the textile comprises knitted heterogeneous yarns.

12. A biocompatible surgical device as in claim 9, wherein the textile comprises woven heterogeneous yarns.

13. A biocompatible surgical device as in claim 9, 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.

14. A biocompatible surgical device as in claim 9, wherein the textile is a braided suture.

15. A suture comprising at least one heterogeneous yarn defining a longitudinal axis and having linear disposed polyester strands in intimate contact with linear disposed polyolefin strands, wherein the plurality of polyester strands and the plurality of the polyolefin strands run parallel to each other and the longitudinal axis along the length of the yarn.

16. A suture as in claim 15, wherein the polyester strands comprise polyethylene terephthalate.

17. A suture as in claim 15, wherein the polyolefin strands comprise polyethylene.

18. A suture as in claim 15, wherein the polyolefin strands comprise ultra high molecular weight polyethylene.

19. A suture as in claim 15, wherein the heterogeneous yarn is coated with a composition containing one or more biologically active materials.

21. A method of manufacturing a yarn for use with a surgical device comprising:

positioning a plurality of heterogeneous strands in side-by-side fashion such that the plurality of heterogeneous strands are maintained in a parallel relation to one another;

applying a binding agent to the plurality of heterogeneous strands; and

setting the binding agent.
