A vascular closure device. In each embodiment, the device includes at least one relatively non-deformable surface member and a conformable and distensible member. Typically the conformable member is implemented as a balloon structure that is inflated with a liquid or gaseous medium. This inflation fluid increases the fluid pressure in the balloon which counteracts the fluid pressure of the punctured vessel. The resulting forces on the balloon are opposed by tissue structures that transfer the load to the surrounding subcutaneous tissue structures. The device may be constructed of bioabsorbable or non-bioabsorbable materials. Additionally, the device may be coated with agents to provide a secondary therapy for enhancement of clotting or prevention of infections. These agents may also elute from the distensible conformal member.

[ What is claimed is:] [1.]1. A device for sealing a vascular access wound in a patient, which includes both a skin puncture and a vessel punctured for vascular access, said device comprising:a) a surface member for placement proximate the patient's skin at the location of said wound, said skin defining a substantially horizontal plane;b) a conformable distensible member having an approximately vertical axis which is approximately perpendicular to said horizontal plane, said conformal distensible member for location proximate said vessel, and coupled to said surface member; d conformable distensible member capable of shape change upon expansion whereby said device seals said vessel by extending the length of said conformal distensible member in the direction along said approximately vertical axis.
