Patent number: 8628567Abstract: A system for repairing body lumens including a modular graft and a method for deploying the graft within the body lumen. The modular graft includes a first component having first and second legs portions which mate with second and third graft components, respectively. The second leg portion has a bell bottom shape. The modular graft further includes expandable members which aid in implanting the modular graft as well as facilitates the mating of its components. In order to repair the body lumen, the first component is placed at the repair site and thereafter the first and second legs are advanced to the repair site and attached to the first component. A further aspect of the invention is a fixation device which is adapted to perform an attachment function. The graft and the fixation device are configured to be axially separated from one another so as to allow the graft to attach to the vascular wall proximal of the graft.Type: GrantFiled: September 29, 2003Date of Patent: January 14, 2014Assignee: Cook Medical Technologies LLCInventors: Timothy A. M. Chuter, David T. Pollock, Tamara L. Trayer

Patent number: 8211139Abstract: A graft provided with a flexible sealing member to substantially prevent blood from leaking between the graft a lumen into which the graft is placed. In one embodiment, the flexible sealing member may be pressed against the vascular wall by an outwardly biased spring means attached to the sealing member. In other embodiments, the sealing member may be self-positioning upon deployment of the graft. The sealing member also may be formed into the shape of a toroid, which may be filled with thrombogenic material causing blood permeating into the toroid-shaped space to coagulate therein and hold the sealing member in place. It is also contemplated that the sealing member be formed from tufts of frayed yarn protruding circumferentially from the outer surface of the graft. A method of manufacturing such tufted yarn sealing members is also disclosed.Type: GrantFiled: December 19, 2008Date of Patent: July 3, 2012Assignee: Endovascular Technologies, Inc.Inventors: Steven G. Baker, Tamara L. Trayer, Arnold M. Escano, Mark LeMere, Elizabeth A. McDermott

Patent number: 8177833Abstract: The present invention provides a system and a method for forming in vivo a junction between a first and a second element of a modular endovascular prosthesis used for repairing defects in vessels and other lumens within the body of a patient. The first element is adapted to have a receiving element, and the second element is adapted to have a protruding element. In the final deployed configuration of the endovascular prosthesis, the protruding element of the second element is adapted to be engaged with the receiving element of the first element, substantially preventing axial separation of the elements relative to each other. The receiving element of the invention may have various forms, and may include a fold in the wall of the first element, an expandable framework having protruding struts, or a flexible thread.Type: GrantFiled: November 8, 2006Date of Patent: May 15, 2012Assignee: Endovascular Technologies, Inc.Inventors: Timothy A.
