Abstract

A surgical fastener assembly for attaching a prosthesis to soft tissue is provided. The surgical fastener assembly includes a continuous helical coil having a distal end and a proximal end. The helical coil is fabricated from an implantable metal. The surgical fastener assembly further includes a cap secured to the proximal end of the helical coil. The cap is fabricated from an implantable polymer.

Claims (18)

1 . A surgical fastener assembly for attaching a prosthesis to soft tissue, the surgical fastener assembly comprising:

a continuous helical coil having a distal end and a proximal end, the helical coil being fabricated from an implantable metal; and

a cap secured to the proximal end of the helical coil, the cap being fabricated from an implantable polymer.

2 . The surgical fastener assembly according to claim 1 , wherein the helical coil has a diameter and defines a coil lumen extending axially therethrough.

3 . The surgical fastener assembly according to claim 2 , wherein the cap defines a central opening axially aligned with the coil lumen of the helical coil.

4 . The surgical fastener assembly according to claim 3 , wherein the cap defines at least one rotation receiving feature for receiving rotational forces from a fastener applying tool.

5 . The surgical fastener assembly according to claim 4 , wherein the at least one rotation receiving feature is defined in an outer surface of the cap.

6 . The surgical fastener assembly according to claim 1 , wherein the implantable metal is stainless steel.

7 . The surgical fastener assembly according to claim 1 , wherein the distal end of the helical coil is a sharpened tip.

8 . The surgical fastener assembly according to claim 1 , wherein the polymer is biodegradable.

9 . The surgical fastener assembly according to claim 6 , wherein the helical coil has a diameter and defines a coil lumen extending axially therethrough.

10 . The surgical fastener assembly according to claim 9 , wherein the cap defines a central opening axially aligned with the coil lumen of the helical coil.

11 . The surgical fastener assembly according to claim 10 , wherein the cap defines at least one rotation receiving surface for receiving rotational forces from a fastener applying tool.

12 . The surgical fastener assembly according to claim 11 , wherein the at least one rotation receiving feature is defined in an outer surface of the cap.

13 . The surgical fastener assembly according to claim 1 , wherein the helical coil has between two and ten turns.

14 . The surgical fastener assembly according to claim 1 , wherein the assembly has a proximal to distal length between one and ten millimeters.

15 . The surgical fastener assembly according to claim 2 , wherein the diameter is between one and six millimeters.

16 . The surgical fastener assembly according to claim 13 , wherein the distance between turns is between one quarter of a millimeter and three millimeters.
