Medical Fastening Device

A tissue fastening device, comprising:

• an elongate member extending between a working end and a control end, the working end having a firing aperture;
• a first arcuate needle disposed within the firing aperture of the working end and adapted to rotate about a first axis in a first direction, entering through a first section of one of a tissue and a prosthetic material, and exiting through a second section of one of the tissue and the prosthetic material;
• a second arcuate needle disposed within the firing aperture of the working end and adapted to rotate about a second axis in a second direction, entering through the second section of one of the tissue and the prosthetic material, and exiting through the first section of one of the tissue and the prosthetic material;
• and
• a drive mechanism operatively coupled to each of the first and second arcuate needles and configured to engage each of the first and second arcuate needles between a retracted position and an extended position in response to user input received through the control end.

A tissue fastening device, comprising:

• an elongate member extending between a working end and a control end, the working end having a firing aperture;
• an arcuate needle disposed within the firing aperture of the working end and rotatable between a retracted position and an extended position, the arcuate needle including a recess configured to engagably receive an end of a fastener therein;
• and
• a drive mechanism operatively coupled to the arcuate needle and configured to, upon actuation, advance the arcuate needle in a forward rotation through one of a tissue and a prosthetic material and engage an end of a fastener to be installed, and upon release, retract the arcuate needle in a reverse rotation through one of the tissue and the prosthetic material to pull the engaged end of the fastener therethrough.

A tissue fastener, comprising:

• an elongated filament having a leading end and a trailing end;
• a needle guide disposed on the leading end;
• and
• a retention member disposed on the trailing end, the retention member being configured to resist advancement through at least one of a tissue and a prosthetic material.
