The anchors can be locked in place to secure the support within the vessel.Type: ApplicationFiled: July 30, 2019Publication date: November 21, 2019Inventors: Mark L. MATHIS, Gregory D.

Publication number: 20190350710Abstract: 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: July 30, 2019Publication date: November 21, 2019Applicant: EVALVE, INC.Inventors: Ted Ketai, Chris Bender, Steven A. Tyler, Troy L. Thornton, Eric A. Goldfarb
