Abstract:
A percutaneous tissue track closure assembly comprising:a barrier assembly comprising: an elongate barrier carrier having a distal end; a semipermeable barrier which permits blood or at least one blood component to pass therethrough but prevents the flowable material from passing therethrough and which comprises a plurality of laterally-expandable arms defining fluid-flow-permitting gaps therebetween when in the deployed configuration at the distal end of the barrier carrier, the barrier being placeable in a laterally retracted, undeployed configuration and a laterally expanded, deployed configuration; and a user-operated barrier actuator coupled to the barrier to move the barrier between the undeployed and deployed conditions; a flowable material assembly comprising: a source of a hemostatic flowable material; a delivery tube having a tube entrance and a tube exit at a chosen position along the barrier carrier, the delivery tube coupleable to the flowable material source; and a flowable material driver selectively driving flowable material from the flowable material source through the tube entrance, along the delivery tube and out of the delivery tube through the tube exit.
