Publication number: 20220175369Abstract: In accordance with one aspect of the disclosure, a surgical fastener is disclosed. The surgical fastener includes a base at a proximal end of the surgical fastener. A first arm and a second arm extend helically from the base about a longitudinal axis towards a distal end of the surgical fastener. A first needle capture zone is disposed on a distal portion of the first arm, and a second needle capture zone is disposed on a distal portion of the second arm. The first needle capture zone and the second needle capture zone are configured to engage with a respective first needle and a second needle when the first and the second needle are extending from a fastener deployment device and disengage with the respective first and second needle when the first and the second needle are retracting into the fastener deployment device.Type: ApplicationFiled: April 3, 2020Publication date: June 9, 2022Applicant: Surgimatix, Inc.Inventors: Jafar S. Hasan, Adam A. Saban, Gary M. Kobylewski
