Abstract:
1. A tissue puncture closure assembly, comprising: a closure device having a distal and a proximal end; a block and tackle disposed in the closure device, a portion of the block and tackle being anchored to the proximal end; a first filament extending from a distal end of the block and tackle; an anchor attached to the first filament at the distal end of the closure device; a sealing plug attached to the first filament between the anchor and the block and tackle; wherein the block and tackle is configured to provide a mechanical advantage to move the sealing plug and the anchor together when the anchor is held in a fixed position, wherein the mechanical advantage comprises a ratio greater than 1:1 between an output force used to move the sealing plug and the anchor together and an input force applied to the closure device, wherein the block and tackle is spaced proximally of the anchor and the sealing plug, and the tackle comprises a continuous second filament that is separate and distinct from the first filament.
