Abstract:
1. A closure device for sealing a percutaneous puncture in a wall of a body passageway, the closure device comprising: an anchor configured to engage an interior surface of the body passageway; an expandable plug; a contiguous elongate filament, comprising a longitudinal axis, coupled to the anchor and the plug, including first and second sections and a collar, the first and second sections extending from the anchor with the first section extending through the collar connected to the second section such that a loop is formed by the first and second sections and the collar, wherein the loop extends through an orifice in the plug; and a lock frictionally engaged to a portion of the first section extending beyond said loop, wherein the collar is located proximal to the plug and distal to the lock between a proximal end of the plug and a distal end of the lock, and wherein the filament extends through an orifice in the lock and the lock is movable along the filament, in either direction along the longitudinal axis of the filament, in response to application of a force on the lock that overcomes the frictional engagement, whereby as the lock is moved along the first section towards the anchor, the loop shrinks causing the plug to move toward the anchor, wherein the lock is configured to prevent the loop from expanding after said shrinkage of the loop.
