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: 7527645Abstract: Delivery systems and methods for delivering modular endovascular graft devices that allow one portion of the repair device to be deployed while maintaining control of the other portions. One system includes an elongate inner member including an anchor stop ring, the anchor stop ring including a plurality of recesses, each sized to receive a portion of the trunk portion and embedding portion of a respective hook in the delivery configuration, each embedding portion extending radially outwardly at an acute angle relative to the trunk portion in the delivery configuration. The delivery systems are simpler to use, easier to manufacture and facilitate better packing of the repair device.Type: GrantFiled: October 28, 2005Date of Patent: May 5, 2009Inventors: Juan I. Perez, Shuji Uemura, Arnold M. Escano, Mark Lemere, Richard Newhauser

Publication number: 20060200220Abstract: A endovascular graft having sensing devices attached thereto to facilitate measurement of pertinent parameters within the vasculature into which the graft is implanted. Power sources and transmitters may be attached to the graft to facilitate transmission of measurements to a receiving device outside the patient's body. The sensing devices, may be electrically passive or integrated devices with measurement and transmission capability. The sensing devices may be attached to specific locations on the graft material or attached to the lumen, thereby providing pertinent parameters from critical points inside the vasculature, or may be dispersed over the surface of the graft material or within the lumen to provide a profile of pertinent parameters. The sensing devices may be attached to the graft material with one suture using a running stitch to minimize graft bulk and may be coated with a material to inhibit or control tissue growth.Type: ApplicationFiled: May 4, 2006Publication date: September 7, 2006Inventors: Peter Brown, Mark Lemere, Kimberly Barkman, Tim Kovac
