Abstract

A surgical fastener having a base, and two legs extending away from the base. The legs have distal end segments. The fastener has a first shape wherein the distal end segments bend towards each other in so that they are adjacent and form the fastener into a first loop. The fastener has a second shape wherein the distal end segments are spaced apart from each other along substantially an entire length thereof. The fastener has a third shape wherein the distal end segments bend towards each other so that they are adjacent and form the fastener into a second loop, wherein the second loop has a width greater than a width of the first loop.

Claims

1. A surgical fastener comprising:

a base, and two legs extending away from said base, said legs having distal end segments;

said fastener having a first shape wherein said distal end segments bend towards each other in so that they are adjacent and form said fastener into a first loop;

said fastener having a second shape wherein said distal end segments are spaced apart from each other along substantially an entire length thereof;

said fastener having a third shape wherein said distal end segments bend towards each other in so that they are adjacent and form said fastener into a second loop, said second loop having a width greater than a width of said first loop.

2. The surgical fastener of claim 1 wherein said legs in said first shape extend from said base in a substantial parallel relationship.

3. The surgical fastener of claim 1 wherein said distal end segments are angled away from said base at least 90 degrees.

4. The surgical fastener of claim 1 wherein said first loop is asymmetric about all planes perpendicular to an axis along a length of said loop.

5. The surgical fastener of claim 1 wherein said base of said first loop is non-linear.

6. The surgical fastener of claim 1 wherein said base of said second loop is plastically deformed.

7. The surgical fastener of claim 1 wherein said base of said second loop is non-linear.

8. The surgical fastener of claim 1 wherein at least a portion of said fastener is absorbable.

9. The surgical fastener of claim 1 wherein at least a portion of said fastener contains a therapeutic agent.

10. The surgical fastener of claim 1 wherein said end segments define a non-zero angle.
