Claim Text:
1. A staple for attaching a sheet-like implant to tissue or bone comprising: a first arm having a proximal end and a distal end; a second arm having a proximal end and a distal end; a bridge extending from the proximal end of the first arm to the proximal end of the second arm; a first fluke extending distally from the distal end of the first arm to a first pointed tip, the first fluke arranged eccentrically to the distal end of the first arm with a first barb extending laterally outward beyond the first arm, the first barb including a proximal surface facing the first arm and projecting at an outward angle in a proximal direction away from the distal end of the first arm to engage the tissue or bone when inserted therein, thereby causing the first fluke to rotate in response to a pullout force on the bridge; and a second fluke extending distally from the distal end of the second arm to a second pointed tip, the second fluke arranged eccentrically to the distal end of the second arm with a second barb extending laterally outward beyond the second arm, the second barb including a proximal surface facing the second arm and projecting at an outward angle in a proximal direction away from the distal end of the second arm to engage the tissue or bone when inserted therein, thereby causing the second fluke to rotate in response to a pullout force on the bridge; wherein the proximalmost surface of the first barb extends at an oblique angle to the proximalmost surface of the second barb.
