Patent number: 6814751Abstract: Graft delivery systems and methods for performing a cardiac by-pass procedure using a graft or a mammary artery are described. A combination of catheters and guide devices through the aorta, coronary artery, and the thoracic region can be used to accomplish these procedures.Type: GrantFiled: January 30, 2002Date of Patent: November 9, 2004Inventor: Todd K. Rosengart

Publication number: 20040220664Abstract: A endovascular graft having at least two thin wall graft members, with at least one of the thin wall graft members configured to be deployed within a lumen of another thin wall graft member. The thin wall graft members may be coupled or connected to each other so as to allow relative axial displacement of the sections, or they may be separate members that have dimensions and a configuration to allow coaxial deployment within inner lumens of each other. By having multiple thin wall graft member, the graft may be built up within a patient's vasculature in steps through a delivery catheter system that is smaller in profile and more flexible than a delivery catheter system configured to deliver a single component graft. The graft of the invention may be delivered percutaneously or intraoperatively.Type: ApplicationFiled: March 17, 2004Publication date: November 4, 2004Applicant: TriVascular, Inc.Inventor: Michael V. Chobotov

Patent number: 6808534Abstract: An improved reduced diameter intraluminal grafting system capable of deploying a bifurcated graft into a bifurcated vessel is described. The system having a pliable jacket guard configured to ensure atraumatic delivery and deployment of the bifurcated graft. The bifurcated graft is comprised of a main tubular member and two tubular legs with attachment systems configured into each of the three ends of the graft. The bifurcated graft along with the mechanisms required to position and attach the bifurcated graft fit within a single delivery catheter for intraluminal delivery. The bifurcated graft, positioning mechanisms and attaching mechanisms are configured such that a small diameter delivery catheter can be utilized. The methods of positioning and attaching the bifurcated graft are also described.Type: GrantFiled: December 17, 2001Date of Patent: October 26, 2004Assignee: Endovascular Technologies, Inc.Inventor: Arnold M. Escano

Publication number: 20040199176Abstract: The present invention relates to an applicator for a prosthesis of the type having a tubular element and distal and proximal flange fingers which are arranged distributed around the periphery of the tubular element and can be brought into a straightened position under spring tension for fitting the prosthesis. The applicator comprises a carrier tube with, at the distal end thereof, a supporting ring that fits in the tubular element; a movable release rod that is housed in the carrier tube and has a distal release ring at the distal end. The distal release ring is provided with an undercut that opens in the proximal direction, extends around the periphery and has an internal peripheral surface facing inwards. This internal peripheral surface lies within or on the outer contour of the external peripheral surface of the supporting ring.Type: ApplicationFiled: December 12, 2003Publication date: October 7, 2004Inventor: Eric Berreklouw

Publication number: 20040199239Abstract: A system for protecting a stent from contact during loading comprises a stent a protective sleeve disposed about the stent and a loading tool. The inner diameter of the protective sleeve is greater than the outer diameter of the stent. The protective sleeve has a length longer than that of the stent. The portion of the sleeve extending beyond the length of the stent defines a sleeve extension. The loading tool is positioned about at the stent retaining sleeve of a catheter. The tip region of the loading tool separates the protective sleeve and the stent from one another when the protective sleeve is pulled over the tip region of the loading tool. When the protective sleeve is pulled over the tip region of the loading tool the stent is advanced into a lumen defined by the stent retaining sleeve of the catheter.Type: ApplicationFiled: April 4, 2003Publication date: October 7, 2004Inventors: Michael Austin, Daniel C. Perreault, Gabriel S. Sobrino

Publication number: 20040193252Abstract: The present invention embodies 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. The delivery systems are simpler to use, easier to manufacture and facilitate better packing of the repair device.Type: ApplicationFiled: March 27, 2003Publication date: September 30, 2004Inventors: Juan I. Perez, Shuji Uemura, Arnold M. Escano, Mark Lemere, Richard Newhauser
