Abstract
A closure device closes an opening in a body cavity. The closure device includes an elongate delivery member and a closure component which is removably connected to the distal end of the delivery member. The closure component has a collapsible backing movable between a non-collapsed position and a collapsed position. The closure component also includes a plurality of fibrous tissue engaging members disposed on the backing and oriented in a non-engaging orientation when traveling in a distal direction and in an engaging orientation when traveling in a proximal direction. The fibrous tissue engaging members become entangled in the backing when the backing is in the collapsed position.
