Patent number: 12226304Abstract: A closure mechanism for closing a tubular portion of a graft that includes a closure element having aperture or looped ends. The closure element is provided around the circumference of a tubular length of graft material and is attached thereto. The closure element is biased into an annular profile by threading a release element through the ends holding them together. In its annular profile, the closure element thus holds the lumen of the tubular length of graft material in an open configuration. Withdrawal of the release element causes the closure element to take on a flat/linear profile, pulling the lumen closed as it does so. The closure mechanism can be used in a vascular implant such as a graft, stent graft, including tubular, bifurcated, and branched stent grafts, an occlusion device, or the like.Type: GrantFiled: February 23, 2022Date of Patent: February 18, 2025Assignee: Cook Medical Technologies LLCInventors: John Mogensen, Nuno Dias
