Surgical fasteners, applicator instruments, and methods for deploying surgical fasteners

摘要

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.

主权项

1. A surgical fastener comprising:
a first leg including a distal end, a proximal end, and a first insertion tip at the distal end of said first leg, said first insertion tip having a first distal piercing point; a second leg including a distal end, a proximal end, and a second insertion tip at the distal end of said second leg, said second insertion tip having a second distal piercing point; a bridge connecting the proximal ends of said first and second legs for forming a closed end of said surgical fastener; said first insertion tip having a first insertion tool seating surface; and said second insertion tip having a second insertion tool seating surface, wherein said first and second distal piercing points are located outside said respective first and second legs, wherein said first and second legs have outer walls that face away from one another in opposite directions, and wherein the distance between said first and second distal piercing points is greater than the distance between the outer walls of said first and second legs that face away from one another in opposite directions, wherein said first and second legs extend along respective longitudinal axes, and wherein said first and second insertion tips are asymmetrical and skewed outwardly relative to said respective longitudinal axes of said first and second legs.
