Patent number: 11944538Abstract: A method of reducing regurgitation between native leaflets of an atrioventricular heart valve includes advancing a delivery catheter through a sheath, wherein the delivery catheter has a valve leaflet coaptation element mounted over a distal end portion. The coaptation element is positioned within the heart valve and is permitted to radially expand from a compressed configuration to an enlarged configuration for filling a gap between the native leaflets of the heart valve. After deployment, the position of the coaptation element is fixed relative to the heart valve, thereby reducing regurgitation between the native leaflets of the heart valve and improving heart function.Type: GrantFiled: May 20, 2022Date of Patent: April 2, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Stanton J. Rowe, Robert S. Schwartz, Robert A. Van Tassel, Vivian Khalil, Erin M. Spinner, Neil S. Zimmerman, Alexander J. Siegel

Publication number: 20230255763Abstract: A method includes advancing a delivery assembly through a patient's vasculature toward a native heart valve of the patient, wherein the delivery assembly comprises a first catheter assembly and a second catheter assembly extending through a shaft of the first catheter assembly, and wherein a support member is in an uncoiled, elongated configuration within a sheath of the first catheter assembly. The support member is deployed from the sheath by pushing the second catheter assembly distally relative to the first catheter assembly so that the support member is uncovered by the sheath and the support member extends around native chordae tendineae and native leaflets of the native heart valve. A prosthetic valve is implanted within the native leaflets of the native heart valve such that the native leaflets are frictionally engaged between the support member and the prosthetic valve.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Ronald J. Hosmer, Erin M. Spinner

Publication number: 20230105858Abstract: A system for reducing regurgitation includes a catheter and a coaptation member disposed along a distal end portion of the catheter, wherein the coaption member is sized to be advanced through a patient’s vasculature in a compressed configuration and wherein the coaptation member is expandable for deployment between leaflets of a native tricuspid valve. The coaptation member includes a frame covered with one or more panels of bioprosthetic tissue or flexible polymer to form a three-sided shape having three convex sides separated by rounded corners. An anchor is coupled to a proximal end portion of the catheter and is shaped for attachment to a vessel wall. After deployment, the anchor secures the position of the coaptation member relative to the native tricuspid valve.Type: ApplicationFiled: December 7, 2022Publication date: April 6, 2023Inventors: Vivian Khalil, Erin M.

Patent number: 11523901Abstract: The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valve—i.e., the mitral valve or tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. A proximal anchoring feature fixes the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.Type: GrantFiled: January 9, 2020Date of Patent: December 13, 2022Assignee: Edwards Lifesciences CorporationInventors: Vivian Khalil, Erin M.

Patent number: 11103347Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native chordae tendineae and/or leaflets of a valve. The support member can comprise a flexible, distensible material to reduce abrasion and other mechanical damage to surrounding structures. A locking member may be used to couple both ends of the support member, forming a support ring. The support member may have two magnetic end portions which can be magnetically coupled to form a support ring. An expandable prosthetic heart valve can be delivered into the native heart valve and expanded within the support band, thereby causing one or more of the native chordae tendineae and/or leaflets of the native heart valve to be frictionally secured between the support ring and the expanded prosthetic heart valve.Type: GrantFiled: January 16, 2019Date of Patent: August 31, 2021Assignee: Edwards Lifesciences CorporationInventors: Ronald J.

Patent number: 9795302Abstract: Implementations of the tissue illumination systems, devices, and methods disclosed herein take advantage of the translucent nature of tissue to reveal properties by light transmission, for example, tissue type, tissue transition locations, underlying structures, and the like, that are not easily distinguished by reflected light. Illuminating a back-side of a translucent tissue permits a user to distinguish between different types of tissue, tissue transition locations, and/or structures that are difficult or impossible to discern under overhead or front-side illumination. Implementations include a light source that is positionable behind a tissue or disposable within a body cavity or duct, for example, within a heart ventricle.Type: GrantFiled: November 21, 2014Date of Patent: October 24, 2017Assignee: Edwards Lifesciences CorporationInventors: Stanton J.
