Patent number: 8685059Abstract: A closure device for sealing a percutaneous puncture in a wall of a body passageway of a living being. In an exemplary embodiment, the closure device includes an anchor configured to be brought into engagement with an interior of the body passageway, a plug including a proximal portion and a distal portion, a filament coupled to the anchor and the plug. The filament may include a first extending section. The closure device further includes a lock attached to the first extending section, wherein the collar is positioned between the lock and the anchor, wherein the lock frictionally engages the first extending section of the filament so that the lock is movable along the filament only in response to application of a force on the lock that overcomes the frictional engagement.Type: GrantFiled: February 11, 2011Date of Patent: April 1, 2014Assignee: Essential Medical LLCInventor: Greg Alan Walters
