Publication number: 20240065838Abstract: An apparatus for deploying a tissue anchor is disclosed. The apparatus includes a catheter tube having a proximal end and a distal end defining the catheter's length, where the distal end has an anchor housing configured to hold a tissue anchor before deployment; and a pusher wire positioned within the catheter tube and extending through the length of the catheter tube. The apparatus is configured to provide a pushing force on the pusher wire from the proximal end of the catheter tube, thus displacing the pusher wire in a distal direction to the pusher wire's fully extended anchor deployment position which in turn deploys the tissue anchor from the anchor housing in the distal direction by pushing the tissue anchor in the distal direction.Type: ApplicationFiled: October 24, 2023Publication date: February 29, 2024Applicant: Micro Interventional Devices, Inc.Inventors: Michael P.
