Patent number: 8568468Abstract: The present embodiments provide a stent-graft for use in a medical procedure that includes a graft having at least first and second reinforced holes disposed in the graft. The first and second reinforced holes may include first and second grommets. In one embodiment, a first stent may be coupled to the graft using at least one suture disposed through the first and second grommets. Alternatively, a first stent may be coupled to the graft, such that the first stent itself is disposed through the first and second grommets. The grommets may include self-sealing properties to reduce leakage around the sutures and/or stent segments that are disposed through the grommets.Type: GrantFiled: December 1, 2008Date of Patent: October 29, 2013Assignee: Cook Medical Technologies LLCInventors: Richard J. Godlewski, Tony C. Hopkins, Shyam S V Kuppurathanam, Julie E. Urbanski

Patent number: 7077429Abstract: The inflatable cushion of the present invention includes at least two panels and one or more heat shield strips. Each panel has an inflatable region, an attachment region, and a peripheral edge. The attachment region is positioned between the peripheral edge and the inflatable region of each panel. An inward fold is disposed between the inflatable region and the attachment region of each panel. The attachment regions of each panel are disposed proximate each other. A heat shield strip is disposed on a portion of the attachment region and the inflatable region of the same panel. A secure fastener secures the attachment regions of each adjacent panel together and secures the heat shield strip to the attachment region on which it is disposed. A frangible fastener secures the heat shield strip to the adjacent inflatable region on which it is positioned.Type: GrantFiled: December 10, 2003Date of Patent: July 18, 2006Assignee: Autoliv ASP, Inc.Inventors: Larry D.

Publication number: 20040140657Abstract: A method of sealing an air-bag (1) is disclosed, the air-bag having a gas flow duct (4) and a plurality of inflatable cells (5), with each cell (5) having a mouth (6) fluidly connecting the cells (5) to the gas flow duct (4). The method involves inserting a sleeve or “parison” of deformable sealant material (8) into the gas flow duct (4), and then blowing a propellant gas into the sleeve (8) so that the sleeve (8) inflates to form a bubble (12) of sealant material in the region of at least one mouth (6) of a cell (5). The propellant gas is blown into the sleeve (8) until at least the or each said bubble (12) bursts, so as to form a sealant layer on the interior of the air-bag (1) in the region of the respective mouth (6).Type: ApplicationFiled: January 21, 2003Publication date: July 22, 2004Inventor: Shyam S.V.
