Patent number: 10251750Abstract: A system for improving cardiac function is provided. A foldable and expandable frame having at least one anchoring formation is attached to an elongate manipulator and placed in a catheter tube while folded. The tube is inserted into a left ventricle of a heart where the frame is ejected from the tube and expands in the left ventricle. Movements of the elongate manipulator cause the anchor to penetrate the heart muscle and the elongate manipulator to release the frame. The installed frame minimizes the effects of an akinetic portion of the heart forming an aneurysmic bulge. Devices and methods are described herein which are directed to the treatment of a patient's heart having, or one which is susceptible to heart failure, to improve diastolic function.Type: GrantFiled: June 22, 2017Date of Patent: April 9, 2019Assignee: Edwards Lifesciences CorporationInventors: Miles D.

Publication number: 20180104049Abstract: An assembly includes an expandable prosthetic heart valve, a catheter shaft, and a stabilization device. The expandable prosthetic heart valve has a valve body and a plurality of leaflets coupled to the valve body. The catheter shaft has a proximal end portion and a distal end portion. The prosthetic heart valve is coupled to the distal end portion of the catheter shaft. The stabilization device is coupled to the catheter shaft adjacent the prosthetic heart valve and is movable between a contracted configuration and an expanded configuration. In the expanded configuration, the stabilization device is configured to contact surrounding tissue adjacent a site of implantation to stabilize the catheter shaft relative to the site of implantation while the prosthetic heart valve is radially expanded from a radially-compressed state to a radially-expanded state at the site of implantation.Type: ApplicationFiled: December 14, 2017Publication date: April 19, 2018Applicant: Edwards Lifesciences CorporationInventors: Jibin Yang, Scott Hyler Heneveld, SR., Matthew L.

Publication number: 20170281345Abstract: A method of implanting a prosthetic heart valve includes advancing the prosthetic heart valve in a radially-contracted configuration into an annulus of a native aortic valve. The prosthetic heart valve includes a self-expanding body and a plurality of leaflets fastened to the body. The body of the prosthetic heart valve is formed with an annulus anchoring section, a sinus section, and an outflow section. During implantation, the prosthetic heart valve is allowed to self-expand such that the annulus anchoring section contacts the annulus of the native aortic valve and the outflow section contacts a native ascending aorta. The outflow section is less rigid than the annulus anchoring section for conforming to the native ascending aorta. The outflow section flares outwardly from the sinus section. The sinus section preferably includes three sinus apertures.Type: ApplicationFiled: June 14, 2017Publication date: October 5, 2017Applicant: Edwards Lifesciences CorporationInventors: Jibin Yang, Matthew L.
