Abstract
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.
