Method and device for sealing puncture wounds in a vascular walls wherein a cylinder of compliant material with a coating of hydrophilic material is placed with one end of the cylinder against the side wall of a vessel. Axial pressure is then applied to the other end of the cylinder to deform the cylinder and flatten it into a disk which increases in lateral dimension and becomes embedded in tissue over the wound. The hydrophilic material expands on the disk to seal the wound. A clot promoter in the coating reverses the effects of heparin and accelerates clot formation.

[ I claim:] [14.] A medical device comprising an introducer sheath adapted to be inserted into a vessel through a puncture in a wall of the vessel, a hollow cylinder of compliant material slidably mounted on the sheath, means for advancing the cylinder along the sheath to bring the distal end of the cylinder into engagement with the wall of the vessel, and means operable upon withdrawal of the sheath for pushing against the proximal end of the cylinder to flatten the cylinder into a disk that increases in lateral dimension and becomes embedded in tissue over the puncture.
