Abstract

A tension-free elastic tape is used for the surgical treatment of female urinary incontinence. The tape has a textile structure that allows ingrowth of the tape into the connective tissue. On its longitudinal edges, the tape has edge threads (2, 4, 6, 8) that project from the textile structure of the tape and that especially facilitate a good primary anchoring of the tape in the tissue. The edge threads are firmly incorporated in the structure of the tape.

Claims

1. Tension-free elastic tape for surgical treatments, comprising:

tape having a textile structure in the form of a knitted fabric, wherein the textile structure enables the ingrowth of connective tissue, the textile structure of the tape comprised of a first thread pattern of base threads, and whereby the tape has longitudinal edges; and

edge threads provided at the edges of the tape in a direction parallel to a longitudinal direction of the tape, the edge threads forming a looped second thread pattern that projects from the longitudinal edges of the thread pattern of base threads and the knitted fabric completed in the peripheral area by the edge threads forming loops on the two longitudinal edges of the tape, said loops projecting laterally in a plane of the tape beyond the edge of the tape without open ends, the loops configured with loop openings greater than 0.01 mm² at the longitudinal edges of the tape, the edge threads provided on the longitudinal edges of the tape and projecting from the textile structure of the tape to ensure a primary anchoring of the tape without coming undone from the textile structure of the tape, and providing a primary anchoring of the tape in the tissue, the edge threads directly and firmly incorporated in the structure of the first thread pattern of said base threads.

2. The tape according to claim 1, wherein the knitted fabric comprises a terry cloth.

3. The tape according to claim 1, characterized in that the tape is formed primarily or exclusively of monofils.

4. The tape according to claim 1, characterized in that the tape is formed primarily of multifils.

5. The tape according to claim 1, wherein the tape comprises non-reabsorbable material.

6. The tape according to claim 1, further comprising:

at least two different filament materials forming the tape; and

a reasorbable material provided as at least one of the filament materials.

7. The tape according to claim 1, characterized in that the edge threads comprise reabsorbable filament material.

8. The tape according to claim 1, characterized in that the edge threads project from the first thread pattern of the base thread with their free ends and are directly incorporated or anchored in the first thread pattern of the base thread.

9. The tape according to claim 1, further comprising a floating thread securing the edge threads.

10. The tape according to claim 1, characterized in that the threads comprises a non-reabsorbable polymer material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyester, polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), other fluoride-containing polymers, polyurethane (PUR), polyetherketone and polyphenylene sulfide.

11. The tape according to claim 1, characterized in that the threads comprises a reabsorbable polymer material selected from the group consisting of alpha and beta hydroxycarboxylic acids, polyglycolic acids (PGA), reabsorbing polymers and polyester amides.

12. The tape according to claim 1, characterized in that:

the tape'"'"'s length exceeds the tape'"'"'s width by more than twenty times, such that a ratio of the length to the width exceeds 20.

13. The tape according to claim 1, characterized in that:

the tape has a length in the longitudinal direction substantially greater than a width of the tape, such that a ratio of the length to the width exceeds 20; and

the edge threads provided at the edges of the tape in the longitudinal direction project from the first thread pattern of the base thread with their free ends, with the edge threads directly incorporated or anchored in the first thread pattern of the base thread.

14. Tension-free elastic tape for surgical treatments, comprising:

tape having a textile structure in the form of a knitted fabric, wherein the textile structure enables the ingrowth of connective tissue, the textile structure of the tape comprised of a first thread pattern of base threads, and whereby the tape has longitudinal edges; and

edge threads provided at the edges of the tape in a direction parallel to a longitudinal direction of the tape, the edge threads forming a looped second thread pattern that projects from the longitudinal edges of the thread pattern of base threads and the knitted fabric completed in the peripheral area by the edge threads forming loops on the two longitudinal edges of the tape, said loops projecting laterally in a plane of the tape beyond the edge of the tape without open ends, the loops configured with loop openings greater than 0.02 mm² at the longitudinal edges of the tape, the edge threads provided on the longitudinal edges of the tape and projecting from the textile structure of the tape to ensure a primary anchoring of the tape without coming undone from the textile structure of the tape, and providing a primary anchoring of the tape in the tissue, the edge threads directly and firmly incorporated in the structure of the first thread pattern of said base threads.

15. The tape according to claim 14, wherein the knitted fabric comprises a terry cloth.

16. The tape according to claim 14, characterized in that the tape is formed primarily or exclusively of monofils.

17. The tape according to claim 14, characterized in that the tape is formed primarily of multifils.

18. The tape according to claim 14, wherein the tape comprises non-reabsorbable material.

19. The tape according to claim 14, further comprising:

at least two different filament materials forming the tape; and

a reasorbable material provided as at least one of the filament materials.

20. The tape according to claim 19, characterized in that the edge threads consist of reabsorbable filament material.

21. The tape according to claim 14, characterized in that the edge threads project from the first thread pattern of the base thread with their free ends and are directly incorporated or anchored in the first thread pattern of the base thread.

22. The tape according to claim 14, further comprising a floating thread securing the edge threads.

23. The tape according to claim 14, characterized in that the threads comprises a non-reabsorbable polymer material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyester, polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), other fluoride-containing polymers, polyurethane (PUR), polyetherketone and polyphenylene sulfide.

24. The tape according to claim 14, characterized in that the threads comprises a reabsorbable polymer material selected from the group consisting of alpha and beta hydroxycarboxylic acids, polyglycolic acids (PGA), reabsorbing polymers and polyester amides.

25. The tape according to claim 14, characterized in that:

the tape has a length in the longitudinal direction substantially greater than a width of the tape, such that a ratio of the length to the width exceeds 20; and

the edge threads provided at the edges of the tape in the longitudinal direction project from the first thread pattern of the base thread with their free ends, with the edge threads directly incorporated or anchored in the first thread pattern of the base thread.
