Abstract
The invention is generally directed to devices and methods for sealing a puncture or an opening through a wall of a blood vessel or a body cavity. The device includes a structural member and a sealing material associated with the structural member. The structural member includes a rod, a first obstructing body and a second obstructing body. The first obstructing body is affixed against an inner surface of the wall of the blood vessel or body cavity and the second obstructing body is affixed against an outer surface of the wall of the blood vessel or body cavity once placed at the puncture or the opening. The sealing material includes a reconstituted or naturally-derived collagenous material, which can expand at the puncture or the opening to restore hemostasis and enhance sealing.
