Abstract:
1. A collapsible tissue anchor device, comprising: a generally tubular sleeve having a distal insertion portion and a lumen extending therethrough, at least one wall portion adapted to provide a collapsing region for the sleeve, and at least one internal tab extending within the lumen and having an angled surface, with distal insertion portion of the sleeve insertable through tissue in a non-collapsed state; and an elongate member having at least one distal head portion and an opposing end portion having at least one tapered flange distal the at least one head portion, with a suture member attached to and extending from the at least one tapered flange of the elongate member, the elongate member adapted for insertion and traversal through at least a portion of the lumen, whereby force exerted by the at least one distal head portion on an outside portion of the sleeve causes the sleeve to collapse around the collapsing region such that the distal insertion portion is collapsed on a side of the tissue to angle down away from the at least one head portion of the elongate member toward the at least one tapered flange such that tips of the insertion portion engage the tissue and restrict pullout, with the at least one tapered flange adapted to travel along the angled surface of the at least one internal tab until the tapered flange securely engages with the at least one internal tab of the sleeve to limit transversal of the elongate member.
