Abstract

A surgical tack, comprising: a single shaft formed of a bio-compatible material and having a tip adapted for entering and engaging bone; and a head mounted on said shaft, said head adapted for engaging a substrate between said head and said bone. Preferably, said shaft is a separate element from said head. Alternatively or additional, said head is rotatable relative to said shaft.

Claims

1. A surgical tack for attaching a substrate to a bone, comprising:

a single shaft formed of a bio-compatible material and having a tip adapted for entering and engaging bone; and

a head mounted on said shaft and comprising between one and three arms, said head adapted for engaging a substrate between said head and said bone.

2. A tack according to claim 1, wherein said shaft is a separate element from said head.

3. A tack according to claim 2, wherein said head is rotatable relative to said shaft.

4. A tack according to any of claims 3claim 2, wherein said head is mounted in a slot defined at an end of said shaft.

5. A tack according to claim 2, wherein said head is mounted on a narrowing of said shaft.

6. A tack according to claim 1, wherein said head comprises only one arm extending substantially perpendicular to said shaft.

7. A tack according to claim 1, wherein said head comprises at least two arms extending substantially perpendicular to said shaft.

8. A tack according to claim 1, wherein said head comprises at least one arm extending at an angle to said shaft.

9. A tack according to claim 1, wherein said head defines a plurality of apertures therethrough.

10. A tack according to claim 1, wherein said head comprises a plurality of protrusions extending in a direction of said tip, which protrusions are adapted for engaging said substrate.

11. A tack according to claim 10, wherein said protrusions are smooth at a portion thereof where they engage said substrate.

12. A tack according to claim 10, wherein said protrusions are pointed at a portion thereof where they engage said substrate.

13. A tack according to claim 10, wherein said protrusions extend at least half a thickness of the substrate.

14. A tack according to claim 10, comprising at least one fin extending from said shaft, distal from said head, and adapted for engaging said bone after insertion of said shaft into said bone.

15. A tack according to claim 14, wherein said at least one fin comprises at least two angularly spaced apart fins.

16. A tack according to claim 14, wherein said at least one fin comprises at least two axially spaced apart fins.

17. A tack according to claim 14, wherein said at least one fin comprises a separate element from said shaft.

18. A tack according to claim 14, wherein said at least one fin is integrally formed with said shaft.

19. A tack according to claim 14, wherein said shaft defines a recess and wherein said at least one fin is adapted for recessing into said defined recess, when force having a vector perpendicular to said shaft is applied to said fin.

20. A tack according to claim 14, wherein said at least one fin is mounted on a separate fin element, which is attached to said shaft.

21. A tack according to claim 1, wherein said head is roughened at a portion thereof that engages said substrate.

22. A tack according to claim 1, comprising an advance-stop on said shaft adjacent said head and separate from said head, such that said advance-stop prevents said head, at portions near said shaft, from touching said bone.

23. A tack according to claim 1, wherein said head has two configurations, one in which it has a first transaxial extent and one in which it has a second transaxial extent, smaller than the first transaxial extent.

47. A kit according to any of claims 1116claim 44, wherein at least one tack comprises at least two tacks.

24. A tack insertion device, comprising:

a “

C”

shaped body;

a handle at one end of said body;

a slotted tack holder adapted to hold a tack, which includes a shaft and at least one arm extending radially from the shaft, such that the shaft of the tack is pointed toward the handle, wherein the holder comprises a slot which is shaped to receive, and frictionally engage, the at least one arm while the tack is held by the tack holder.

25. A device according to claim 24, wherein the holder comprises a plurality of slots.

26. A device according to claim 24, wherein said tack holder is adapted to engage a tack having an apertured head.

27. A device according to claim 24, comprising a second tack holder attached to said body at an offset from said first tack holder.

28. A device according to claim 27, wherein said device comprises a selectable offsetting mechanism for setting said offset.

29. A device according to claim 24, wherein said device comprises a safety release mechanism that prevents the release of said tack.

44. A kit, comprising:

a sling formed of bio-compatible material and having a length and mechanical properties suitable for bladder neck supporting; and

at least one tack, having a head and a shaft, wherein said head has an extent perpendicular to the shaft, which extent is greater by at least 50% from a diameter of the shaft.

45. A kit according to claim 44, wherein said sling contains at least one pre-punched aperture.

46. A kit according to claim 44, wherein said sling contains at least two adjacent pre-punched aperture, for setting an effective sling size.

48. A kit according to claim 44, wherein said sling is reinforced at least at its ends.

49. A kit comprising:

a sling formed of bio-compatible material and having a length and mechanical properties suitable for bladder neck supporting; and

a clip adapted to hold said sling against a tacking head of at least a particular tacking or stapling device.

50. A surgical tack for attaching a substrate to a bone, comprising:

a single shaft formed of a bio-compatible material and having a tip adapted for entering and engaging bone; and

at least one bar shaped beam coupled to the shaft such that the beam extends from opposite radial sides of the shaft, said at least one beam adapted for engaging a substrate to said bone.
