Abstract
A percutaneous tissue track closure assembly ( ) includes a semipermeable barrier ( ) mounted to the distal end of a tubular barrier carrier ( ). The barrier is passed down a tissue track ( ) and into a blood vessel ( ) where the barrier is expanded to close off the blood vessel opening ( ). A syringe device is used to drive a hemostatic flowable material ( ) through a delivery tube ( ) and into the tissue track. The semipermeable barrier permits blood to flow therethrough but prevents passage of the hemostatic flowable material therethrough. The hemostatic material includes a material which swells upon contact with blood, and a blood clotting agent. After an appropriate period of time, the barrier is collapsed and the barrier carrier and delivery tube are removed from the tissue track.
