Abstract

A surgical suture includes a filamentary braid including filamentary elements (16; 20; 216; 220a-e; 34; 36; 44) projecting from the filamentary braid for anchoring in biological tissues.

Claims

1. A surgical suture comprising a filamentary braid including filamentary elements projecting from the filamentary braid for anchoring in biological tissues.

2. The surgical suture according to claim 1, wherein the projecting filamentary elements come from filaments of the filamentary braid and/or from filaments of a core of the filamentary braid.

3. The surgical suture according to claim 1, wherein the projecting filamentary elements comprise ends of the filamentary braid and/or of a core of the filamentary braid, and/or filamentary loops.

4. The surgical suture according to claim 3, wherein the filamentary loops comprise floats, overfeeds and/or velour loops.

5. The surgical suture according to claim 1, wherein the projecting filamentary elements comprise opened filamentary opened floats, opened overfeeds and/or opened velour loops.

6. The surgical suture according to claim 1, wherein the projecting filamentary elements are in a reinforced state.

7. The surgical suture according to claim 1, wherein the projecting filamentary elements have a separation of 0.2 to 10 mm relative to each other measured From exit points of the filamentary elements from the filamentary braid, in the longitudinal direction of the suture.

8. The surgical suture according to claim 1, wherein the filaments having the projecting filamentary elements account for a proportion of 2 to 50%, based on the total number of filaments in the filamentary braid.

9. The surgical suture according to any claim 1, wherein the filamentary braid is formed from mono- and/or multifilaments.

10. The surgical suture according to claim 1, wherein the filamentary braid includes multiplied filaments.

11. The surgical suture according to claim 1, wherein the projecting filamentary elements comprise single filaments coming from multiplied filaments.

12. The surgical suture according to claim 1, wherein the filaments whose elements project from the filamentary braid have a higher flexural stiffness than remaining filaments of the filamentary braid.

13. The surgical suture according to claim 1, wherein the projecting filamentary elements come from filaments having a flexural stiffness between 10 and 600 mN.

14. The surgical suture according to claim 1, wherein the projecting filamentary elements come from monofilaments of the filamentary braid.

15. The surgical suture according to claim 1, wherein the filaments whose elements project from the filamentary braid have a higher linear density than remaining filaments of the filamentary braid.

16. The surgical suture according to claim 1, wherein the projecting filamentary elements come from filaments having a linear density between 10 and 2500 dtex.

17. The surgical suture according to claim 1, wherein the projecting filamentary elements have a length between 0.05 and 3 mm.

18. The surgical suture according to claim 1, wherein the projecting filamentary elements have a diameter between 30 and 250 μ

m.

19. The surgical suture according to claim 1, wherein the filamentary braid is a flat braid.

20. The surgical suture according to claim 1, wherein the filamentary braid is a round or tubular braid which includes a core.

21. A process for producing a suture according to claim 1, comprising:

producing the filamentary braid by braidingly intertwining filaments to form a braided structure; and

forming filamentary elements projecting from the braided structure by leading individual filaments during braiding out of the braided structure which forms.

22. The process according to claim 21, wherein the filaments which have been led out are led back into the braided structure and/or other filaments are led into the braided structure to keep the number of filaments substantially constant.

23. The process according to claim 21, wherein after every leading out of a filament a filament is inserted into the braided structure.

24. The process according to claim 21, wherein the filaments which have been led out are cut off, more particularly to a length between 0.05 and 3 mm.

25. The process according to claim 21, wherein the filaments which have been led out are led back into the braided structure with the formation of loops and, optionally, the loops are opened.

26. The process according to claim 21, wherein the filaments are taken at least doubled in the braiding operation.

27. A surgical kit comprising a suture according to claim 1 and at least a surgical needle.
