Surgical stapling device
First Claim
1. A surgical stapling device, comprising:
- an elongate housing;
a surgical staple slidable longitudinally within the housing towards a free forward end thereof, the staple having two forwardly pointing legs and a back having a rearward extension;
an actuator slidable forwardly within the housing for driving the staple towards the free end of the housing;
means for restraining the rearward extension on the back of the staple against forward movement beyond a predetermined point such that further forward movement of the actuator bends the staple to bring the free ends of the legs towards one another to close the staple; and
means for releasing the closed staple.

Abstract
A surgical stapler comprises an elongate housing 10 and a surgical staple 14 slidable longitudinally within the housing towards the free forward end thereof. The back 18 of the staple has a rearward extension 22. An actuator 16 is slidable forwardly within the housing for driving the staple towards the free end of the housing. An upstanding flange 30 on the extension 22 engages a stop 32 within the housing to restrain the back of the staple against forward movement of the actuator bends the staple to bring the free ends of the legs towards one another to close the staple. Further movement of the actuator then ruptures the join between the extension and the back of the staple to release the closed staple.

11. A surgical stapling device, comprising:
an elongate housing adapted to slidably receive a surgical staple and to drive a staple forwardly to a predetermined position at which an extension on the staple is effective to restrain the staple to the predetermined position and further forward movement of the staple is effective to bend at least one leg on the staple and to release the staple from the extension. - View Dependent Claims (12, 13)

14. A method for closing a puncture wound in tissue, comprising:
-
positioning a forward end of an elongate housing adjacent to a puncture wound in tissue; advancing an actuator forwardly through the elongate housing to advance a staple to a predetermined position, the staple having a restraining means for restraining the staple against further forward movement; further advancing the actuator forwardly to move at least one leg on the staple to close the staple, and to release the staple from the restraining means. - View Dependent Claims (15, 16)
