摘要：
A device for closure of an opening formed in a body vessel includes a grasping member and a sheath movable thereover. The grasping member comprises a tubular body having a plurality of grasping fingers extending from a distal end of the tubular body. The fingers radially extend from the tubular body at a first angle, and are collapsible therefrom to a second angle. The fingers have a distal tip configured for grasping an outer wall of the body vessel surrounding the vessel opening when the fingers are at the first angle. The sheath is slidable over the tubular body and at least a portion of the grasping fingers for collapsing the fingers from the first angle to the second angle, thereby causing the collapsed fingers to at least substantially close the opening.
