Device and method sealing puncture wounds

摘要

A device is proposed for inserting hemostatic material through a tissue channel and against the outside wall of a blood vessel of a patient, wherein the blood vessel wall has a puncture therein adjacent the tissue channel. The device includes a charge of hemostatic material and a hollow sheath adapted to pass through the tissue channel, the sheath having a cross sectional profile larger than the puncture. The device places the hemostatic material in the hollow sheath and advances the hemostatic material through the sheath to the outside of the vessel wall around the puncture.
