Patent ID: 8821537

Claim:
A staple for attaching a sheet-like implant to soft tissue or bone comprising: a first arm, having a proximal end and a distal end, and a second arm having a proximal end and a distal end with a bridge extending from the proximal end of the first arm to the proximal end of the second arm; a first fluke having a proximal end abutting the distal end of the first arm, the first fluke extending distally from the first arm, the first fluke having a lateral extent larger than a lateral extent of the first arm and mounted eccentrically thereto, the first fluke including a proximal surface projecting at an outward angle in a proximal direction away from the distal end of the first arm, the first fluke including a distal pointed surface, the first fluke configured to engage the soft tissue or bone when inserted therein and the first fluke configured to rotate toward a toggled position in response to a normal pullout force on the bridge when the first fluke engages soft tissue or bone the first fluke having a lumen extending at least partially therein from the proximal end, wherein the distal pointed surface of the first fluke is asymmetrical relative to a longitudinal axis of the first fluke; and, a second fluke having a proximal end abutting the distal end of the second arm, the second fluke extending distally from the second arm, the second fluke having a lateral extent larger than the lateral extent of the second arm and mounted eccentrically thereto, the second fluke including a proximal surface projecting at an outward angle in a proximal direction away from the second arm, the first fluke including a distal pointed surface, the second fluke configured to engage the soft tissue or bone when inserted therein and the second fluke configured to rotate toward a toggled position in response to a normal pullout force on the bridge when the first fluke engages soft tissue or bone, wherein the first arm, second arm, first fluke, second fluke, proximal surfaces, and bridge are integrally formed.
