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 additionally, said head is rotatable relative to said shaft.

Claims

1. 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,

wherein said head comprises only one arm extending substantially perpendicular to said shaft.

2. 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,

wherein said head comprises at least two arms extending substantially perpendicular to said shaft.

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

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

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

6. A tack according to claim 3, wherein said head is mounted on a narrowing of said shaft.

7. 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,

wherein said head comprises at least one arm extending at an angle to said shaft.

8. 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,

wherein said head defines a plurality of apertures therethrough.

9. A tack according to claim 8, 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.

10. 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,

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,

wherein said at least one fin comprises at least two angularly spaced apart fins.

11. A tack according to claim 10, wherein said at least one fin is integrally formed with said shaft.

12. A tack according to claim 10, wherein said at least one fin is mounted on a separate fin element, which is attached to said shaft.

13. 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, 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,

wherein said at least one fin comprises at least two axially spaced apart fins.

14. A tack according to claim 13, 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.

15. 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,

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,

wherein said at least one fin comprises a separate element from said shaft.

16. 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,

wherein said head is roughened at a portion thereof that engages said substrate.
