Abstract
A tissue anchor delivery device includes a handle, an elongate shaft extending from the handle, a pusher tube disposed at least partially within a lumen of the elongate shaft, a pusher hub coupled to the pusher tube, a needle disposed at least partially within a lumen of the pusher tube, a needle hub coupled to the needle, and an actuator configured to be fixed to the pusher hub and the needle hub. The actuator is further configured to advance the needle hub and the pusher hub a first distance, thereby causing a tip of the needle to protrude from a distal end of the elongate shaft, disengage from the needle hub, and advance the pusher hub a second distance relative to the needle hub, thereby causing a distal end of the pusher tube to advance over the needle and push a coiled suture form off of the needle.
