SELF-EXPANDING HEMOSTATIC DEVICES AND METHODS FOR FASCIA AND VESSEL PASSAGES

摘要

A vascular closure device (40) comprising an outer housing (42) having an elongate configuration with an axial length greater than a transverse dimension thereof and having a plurality of anchor deployers which are slidably disposed within the outer housing (42) and which are configured to extend and spread from the distal section of the outer housing (42), each anchor deployer comprising a deployment rod (64), an anchor (68) which is removably secured to the distal end of the deployment rod (64), and a filament (72) which includes a distal end which is secured to the anchor (68). The vascular closure device further comprises an inner hemostatic assembly including an elongated shaft (92) that is axially slidable within the inner lumen of the outer housing (42) and a self-expanding plug (104) disposed on the distal section of the elongated shaft (92).
