Surgical Fastening Device

A method of installing a surgical fastener in a tissue, the method comprising:

• loading the surgical fastener at a needle interface of a fastener deployment device;
• extending a first needle and a second needle along a first helical arm and a second helical arm of the surgical fastener;
• engaging the first needle with a first needle capture zone disposed on a distal portion of the first helical arm and engaging the second needle with a second needle capture zone disposed on a distal portion of the second helical arm;
• pulling, by the first and second needle capture zones, the surgical fastener through the tissue;
• and
• retracting the first and second needles to disengage the first and second needles from the respective first and second needle capture zones.

A fastener deployment device comprising:

• a first spiral needle and a second spiral needle, the first and second spiral needles disposed at a distal end of the fastener deployment device;
• a drive shaft extending along a longitudinal axis, the drive shaft being disposed within an outer sleeve and coupled to the first and second spiral needles;
• a drive mechanism at a proximal end of the fastener deployment device, the drive mechanism being operatively coupled to the drive shaft and configured to extend both the first and second spiral needles axially along and radially around the longitudinal axis simultaneously, wherein the fastener deployment device is configured to install a surgical fastener, the surgical fastener comprising:
• a base at a proximal end of the surgical fastener;
• a first arm and a second arm, the first arm and the second arm extending helically from the base about the longitudinal axis towards a distal end of the surgical fastener;
• a first needle capture zone disposed on a distal portion of the first arm;
• and
• a second needle capture zone disposed on a distal portion of the second arm, wherein the first needle capture zone and the second needle capture zone are configured to engage with the first spiral needle and the second spiral needle when the first and second spiral needles are extending from the fastener deployment device and disengage from the respective first and second spiral needles when the first and second spiral needles are retracting into the fastener deployment device.
