ABSTRACT:
A hemostasis device for percutaneously sealing a puncture in the wall of a blood vessel includes a rigid post, and a foot, a seal and a retaining member mounted on the rigid post. The hemostasis device may be deployed in the puncture so that the foot is positioned within the blood vessel. Tension is applied to the rigid post to hold the foot against the inside surface of the blood vessel. The retaining member is then pushed along the length of the rigid post, advancing the seal to a deployed state against the outside surface of the blood vessel. The puncture in the blood vessel is sandwiched between the foot and the seal in the deployed state. The rigid post, foot, seal and retaining member may all be formed from a resorbable polymeric material.
