Abstract

A surgical tack for use in surgical procedures. The surgical tack has a base member and a distally extending spiral member having a distal piercing point. The spiral member forms a spiral. The tack may be used to fasten tissue, sutures, or medical devices to tissue.

Claims

1. A tack for use in a surgical procedure, the tack comprising:

a base member having a top surface and a bottom surface, wherein the base member comprises two intersecting perpendicular members having outer ends and distally extending retention members extending from the outer ends;

a spiral member extending from the bottom of the base member, said spiral member having at least one outer edge, the spiral member having a distal end, wherein the spiral member forms a spiral, said spiral comprising at least one coil, a longitudinal axis and an interior passage; and

,

piercing means extending from the distal end of the spiral member.

3. The tack of claim 1 wherein the spiral member has a substantially rectangular cross-section.

4. The tack of claim 1 wherein the coil has a triangular configuration.

5. The tack of claim 1 further comprising a surgical suture mounted thereto.

6. The tack of claim 1 further comprising suture mounting means extending from the top surface of the base number.

7. The tack of claim 6 wherein the suture mounting means comprises a proximally extending member having a suture receiving hole therein.

2. The tack of claim wherein the spiral member has a substantially parabolic cross-section.

8. A method of surgically fastening tissue comprising:

inserting a surgical tack into one side of a section of tissue, wherein the tack comprises;

a proximal base member having a top surface and a bottom surface, wherein the base member comprises two intersecting perpendicular members having outer ends and distally extending retention members extending from the outer ends;

a distal spiral member extending from the bottom of the base member, said spiral member having at least one outer edge, the spiral member having a distal end, wherein the spiral member forms a spiral, said spiral comprising at least one coil, a longitudinal axis and an interior passage; and

,

piercing means extending from the distal end of the spiral member.
