Patent number: 7112217Abstract: An endovascular graft system used to repair aneurysms in arteries which bifurcate such as the aorta which bifurcates at the aortoiliac junction. The graft system includes two legs, each defining a lumen. Each leg comprises an aortic stent, a graft component and an iliac stent. The graft component is affixed at one end to the aortic stent and at the other end to the iliac stent. Each leg of the graft system is preferably a mirror image of the other with the exception of the aortic stents. The graft component of each leg includes a means for allowing in situ adjustment of the length of the leg to accommodate the different sizes required for different patients.Type: GrantFiled: August 31, 2000Date of Patent: September 26, 2006Assignee: Cordis CorporationInventors: Chad J. Kugler, John R. Drontle, Peter T. Keith, Thomas V. Ressemann, Matthew J. Olson, Thomas K. Heiland

Patent number: 6884260Abstract: The invention provides an endovascular graft system for repair of aneurysms. The graft system includes a trunk component and first and second leg components. The graft components include graft material supported by a plurality of stents which are spaced apart and affixed to the graft material in a manner that allows articulation of the graft system without excessive wear of the graft material. The stents are formed by intersecting struts which may be tapered to relieve stress. A stabilizing mechanism is provided to stabilize the position of the legs with respect to the trunk when the graft system is deployed.Type: GrantFiled: January 14, 2003Date of Patent: April 26, 2005Assignee: Cordis CorporationInventors: Chad J. Kugler, John R. Drontle, Matthew J. Olson, Thomas K. Heiland, Peter T. Keith
