Patent number: 8409273Abstract: Devices, systems, methods and kits are provided for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by a multi-catheter guiding system which is positioned in a desired configuration, generally directed toward the target tissue. Interventional devices may then be passed through the guiding system to the target tissue. Depending on the location of the target tissue and the desired angle of approach, the guiding system may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. The multi-catheter guiding system of the present invention comprises an outer guiding catheter and a coaxially positioned inner guiding catheter, each of which independently form curvatures so that together the curves properly direct the interventional device.Type: GrantFiled: October 30, 2007Date of Patent: April 2, 2013Assignee: Abbott Vascular IncInventors: Troy L. Thornton, Brian B. Martin, Amy R. Raatikka, Yen C. Liao, William D. Kolosi, Pedro Lucatero

Publication number: 20100298929Abstract: Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.Type: ApplicationFiled: January 19, 2010Publication date: November 25, 2010Inventors: Troy L. Thornton, Ferolyn T. Powell, Eric A. Goldfarb, Jan Komtebedde, Kent D. Dell, Pedro B. Lucatero, Francisco J. Valencia, Murli Srinivasan, Roger A. Goodgion, Sandra Saenz, Sylvia Erickson, Sylvester B.
