Claim Text:
1. A fastening device, comprising: a first arcuate needle 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 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, wherein the drive mechanism is configured to, upon actuation, advance each of the first and second arcuate needles in a forward rotation through one of the tissue and the prosthetic material to engage ends of a fastener to be installed; and upon release of the drive mechanism, retract each of the first and second arcuate needles in a reverse rotation through one of the tissue and the prosthetic material to pull the engaged ends of the fastener into a helical configuration.
