Abstract

Braids and surgical devices are made from yarns that include at least one filament made from a thermoplastic elastomer copolymer and at least one filament made from a polyolefin material.

Claims

1. A surgical device comprising first yarns and second yarns in a braided construction, wherein the first yarns comprise at least one filament comprising a thermoplastic elastomer copolymer, and the second yarns comprise at least one filament comprising a polyolefin material.

2. The surgical device according to claim 1, wherein the thermoplastic elastomer copolymer comprises a polyester-ether block copolymer including a polybutylene terephthalate and a long chain polyether glycol, and the polyolefin material comprises polyethylene.

3. The surgical device according to claim 1, wherein the first yarns and the second yarns are multifilament yarns.

4. The surgical device according to claim 1, wherein the device is selected from the group consisting of sutures, meshes, sternal closure devices, cables, tapes and tethers.

5. The surgical device according to claim 1, wherein all the filaments of the first yarn comprise a thermoplastic elastomer copolymer and all the filaments of the second yarn comprise a polyolefin material.

19. A method of closing a wound in tissue comprising:

providing a surgical device in accordance with claim 1;

passing said surgical device through the tissue; and

securing the ends of said surgical device to approximate the tissue.

6. A heterogeneous yarn comprising at least one filament comprising a thermoplastic elastomer copolymer, and at least one filament comprising a polyolefin material.

7. A heterogeneous yarn according to claim 6, wherein the thermoplastic elastomer copolymer comprises a polyester-ether block copolymer including a polybutylene terephthalate and a long chain polyether glycol, and the polyolefin material comprises polyethylene.

8. A surgical device comprising a heterogeneous yarn in accordance with claim 6.

9. A surgical device according to claim 8, wherein the device is selected from the group consisting of sutures, meshes, sternal closure devices, cables, tapes and tethers.

10. A sterile braid comprising a heterogeneous yarn in accordance with claim 6.

11. A multifilament surgical device comprising:

a plurality of heterogeneous yarns, each heterogeneous yarn including first and second filaments; and

the plurality of heterogenous yarns being in a braided construction,

wherein the first filaments comprise a thermoplastic elastomer copolymer, and the second filaments comprise a polyolefin material.

12. The multifilament surgical device according to claim 11, wherein the thermoplastic elastomer copolymer comprises a polyester-ether block copolymer including a polybutylene terephthalate and a long chain polyether glycol, and the polyolefin material comprises polyethylene.

13. The multifilament surgical device according to claim 11, wherein the device is selected from the group consisting of sutures, meshes, sternal closure devices, cables, tapes, and tethers.

20. A method of securing soft tissue to hard tissue comprising:

providing a surgical device in accordance with claim 11;
