Abstract

A surgical fastener for securing a prosthetic device to tissue includes a first leg having a distal end, a proximal end, and a first insertion tip at the distal end of the first leg, and a second leg including a distal end, a proximal end, and a second insertion tip at the distal end of the second leg. A bridge connects the proximal ends of the first and second legs for forming a closed end of the surgical fastener. The first insertion tip has a first insertion tool seating surface, and the second insertion tip has a second insertion tool seating surface. The first insertion tool seating surface is closer to the distal end of the first leg than the proximal end of the first leg, and the second insertion tool seating surface is closer to the distal end of the second leg than the proximal end of the second leg. The first and second legs extend along respective longitudinal axes, and the first and second insertion tips are skewed outwardly relative to the respective longitudinal axes.
