Abstract

A tissue anchoring system includes a tissue anchor member that is suitable for anchoring against tissue. The system also includes a tensioning member operatively connected to the anchor member such that the anchor member can slide relative to the tensioning member, the tensioning member capable of being pulled to cause the anchor member to move relative to the tensioning member into a position seated against the tissue. A hand operated deployment catheter is operable to extend and deploy the anchor member therefrom. The deployment catheter includes a rotatable member about which the tensioning member is routed and a clutch assembly for limiting tension within the tensioning member to prevent the deployed anchor from being pulled through the tissue.
