Patent number: 10265200Abstract: The present embodiments provide an endoluminal prosthesis, such as a stent-graft, having a relatively low delivery profile. In one embodiment, the prosthesis comprises a membrane, and at least one stent having contracted and expanded states, where the stent is coupled to the membrane and maintains patency in the expanded state. The prosthesis further may comprise selectively oriented axial and/or circumferential fibers arranged at predetermined locations along the length and circumference of the prosthesis. An increased population density of the circumferential and/or axial fibers may be provided in areas in which the at least one stent portion is attached to the membrane, or in areas of higher physiological loads imposed upon the endoluminal prosthesis.Type: GrantFiled: August 10, 2010Date of Patent: April 23, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Steven J.

Patent number: 9839538Abstract: A method of making a stent-graft is provided. The method includes mounting a stent on a mandrel so that the stent is stretched when it is on the mandrel. A graft layer is then adhered to the stent while it is mounted on the mandrel. When the stent-graft is removed from the mandrel, the stent contracts and the graft layer becomes partially wrinkled when the stent is in its expanded relaxed state.Type: GrantFiled: June 22, 2015Date of Patent: December 12, 2017Assignee: Cook Medical Technologies LLCInventors: David D Grewe, Keith R Milner, Blayne A Roeder, Steven J Charlebois

Patent number: 9788933Abstract: An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D?24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.Type: GrantFiled: October 28, 2011Date of Patent: October 17, 2017Assignee: Cook Medical Technologies LLCInventors: Jichao Sun, Jarin Kratzberg, David D.

Patent number: 9757263Abstract: A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter-reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter-reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.Type: GrantFiled: November 12, 2010Date of Patent: September 12, 2017Assignee: Cook Medical Technologies LLCInventors: Blayne A.
