Publication number: 20250000654Abstract: Fixation device for fixation of leaflets of a heart valve includes a central assembly and at least one arm moveably coupled relative to the central assembly. The at least one arm includes a deformable frame having a first end and a second end and a longitudinal axis defined therebetween, the second end being moveable between a closed position and an open position. The deformable frame further includes first and second deformable flex portions, each flex portion extending along a respective lateral side of the deformable frame and having a deformed condition and an undeformed condition, and each flex portion having an outer lateral edge. The at least one arm has a maximum deformed arm lateral cross-dimension with the flex portions in the deformed condition.Type: ApplicationFiled: August 30, 2024Publication date: January 2, 2025Applicant: Evalve, Inc.Inventors: Chad Abunassar, Santosh Prabhu, Casey Barbarino, Jessie Garcia, Gabriel Gonzales, Brandon Chu, Tamer M.

Patent number: 11504064Abstract: The present disclosure relates to delivery devices and interventional devices configured to enable monitoring of pressure and other hemodynamic properties before, during, and/or after a cardiac procedure. A guide catheter includes a routing lumen or a routing groove for routing a sensor wire to a desired location during a cardiac procedure. A guide catheter includes one or more pressure sensors positioned to provide desired pressure measurements when the guide catheter is deploying an interventional device. An interventional device may also include one or more associated sensors for providing hemodynamic information before, during, and/or after deployment.Type: GrantFiled: July 27, 2017Date of Patent: November 22, 2022Assignee: EVALVE, INC.Inventors: Chad J. Abunassar, Brandon W. Chu, Patricia H. Ho, Koji J. Kizuka, Benjamin L. Lee, Tamer M. Mahmoud, Sean A. McNiven, Scott C. Mosher, Santosh V. Prabhu, Lauren G. Troxler, Dylan T. Van Hoven

Patent number: 10342958Abstract: A method for improving function of a cardiac valve in a patient, the cardiac valve having at least one leaflet that is attached to a papillary muscle: Inserting a balloon, that is in a first uninflated condition and having a first diameter, within tissue that is part of to the papillary muscle, and thereby separating tissue that was previously connected together, by a maximum amount equal to the first diameter; inflating the balloon to a second inflated condition having a second diameter greater than the first diameter, thereby permanently stretching tissue in the papillary muscle and separating the tissue from the first diameter to a maximum amount equal to the second diameter; deflating the balloon to the first uninflated condition, and thereby returning the tissue to a separation of a maximum amount substantially equal to the first diameter; and then removing the balloon from the patient.Type: GrantFiled: June 30, 2017Date of Patent: July 9, 2019Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Michael F. Wei, Anna M. Snell, Tamer M. Mahmoud, Scott C. Mosher
