SYSTEM AND METHOD FOR SEALING VASCULAR PENETRATIONS WITH HEMOSTATIC GELS

摘要

Systems and method for sealing vascular penetrations rely on placement of a temporary barrier (26) on the posterior side of the penetration. Penetrations are then sealed by delivering a hemostatic gel to a region over the penetration, where the barrier (26) both inhibits loss of the gel and promotes back flow of blood into the gel. A combination of natural clotting factors in the blood and hemostatic agents in the gel promote rapid and effective sealing of the vascular penetration. Specific systems for performing the method include a barrier carrier (20) for temporary placement of the barrier (26) within the blood vessel (18) and a gel delivery tube (34) which may be positioned within a tissue tract or line of penetration simultaneously with the barrier carrier (20) to deliver the hemostatic gel.
