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

A surgical fastener for anchoring medical devices to tissue comprising:

• a first leg having a distal end, a proximal end, a first alignment guide extending between the distal and proximal ends of said first leg, and a first insertion tip at the distal end of said first leg, wherein said first insertion tip comprises a proximal end including a first insertion tool seating surface having a convex shape;
• a second leg having a distal end, a proximal end, a second alignment guide extending between the distal and proximal ends of said second leg, and a second insertion tip at the distal end of said second leg, wherein said second insertion tip comprises a proximal end including a second insertion tool seating surface having a convex shape;
• and
• a bridge connecting the proximal ends of said first and second legs for forming a closed end of said surgical fastener, wherein said first alignment guide extends to the distal end of said first leg for intersecting with said first insertion tool seating surface, and said second alignment guide extends to the distal end of said second leg for intersecting with said second insertion tool seating surface, 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.

A surgical fastener for anchoring medical devices to tissue comprising:

• a first leg having a distal end, a proximal end, a first alignment guide extending between the distal and proximal ends of said first leg, and a first insertion tip at the distal end of said first leg, wherein said first insertion tip has a first insertion tool seating surface having a curved shape;
• a second leg having a distal end, a proximal end, a second alignment guide extending between the distal and proximal ends of said second leg, and a second insertion tip at the distal end of said second leg, wherein said second insertion tip has a second insertion tool seating surface having a curved shape;
• and
• a bridge connecting the proximal ends of said first and second legs for forming a closed end of said surgical fastener, wherein each of said first and second insertion tips has a distal piercing point that defines a distal-most end of said insertion tip, and wherein said distal piercing points are located outside said respective first and second legs, 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.
