Publication number: 20230380966Abstract: A method of delivery a prosthetic heart valve includes inserting a delivery apparatus and a prosthetic heart valve into a patient's vasculature. The delivery apparatus includes a steerable guide catheter, a balloon catheter, and a flex indicator. The balloon catheter extends coaxially through the guide catheter, the prosthetic heart valve is mounted on a distal end portion of the balloon catheter, and the flex indicator is movably coupled to a handle of the guide catheter. The method further includes adjusting flexion of a steerable section of the guide catheter to position the prosthetic heart valve. The flex indicator moves relative to the handle of the guide catheter as the flexion of the steerable section is adjusted, and the handle comprises one or more visual indicators adjacent the flex indicator to provide visual indication of an amount of flexion of the steerable section of the guide catheter.Type: ApplicationFiled: August 7, 2023Publication date: November 30, 2023Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Thanh Huy Le, Tri D. Tran, Ronaldo C. Cayabyab, David M. Taylor, Antonio O. Vidal, Robert Bowes, Tram Ngoc Nguyen, Walter Lee

Patent number: 10478296Abstract: An apparatus for delivering a prosthetic heart valve includes a steerable guide catheter, a balloon catheter, and a flex indicator. The guide catheter has a handle and a guide tube extending from the handle. The guide tube has a distal end portion comprising a steerable section. The guide catheter further includes an adjustment mechanism on the handle and a pull wire connecting the adjustment mechanism to the steerable section for changing flexion of the steerable section. The balloon catheter includes a shaft extending coaxially through the guide tube. The shaft includes a proximal end portion and a distal end portion. The balloon catheter further includes a balloon mounted on the distal end portion of the shaft. The flex indicator moves relative to the handle upon adjustment of the adjustment mechanism. The handle includes visual indicia adjacent the flex indicator to provide visual indication of the flexion of the steerable section.Type: GrantFiled: November 20, 2018Date of Patent: November 19, 2019Assignee: Edwards Lifesciences CorporationInventors: Thanh Huy Le, Tri D.

Patent number: 10456253Abstract: A heart valve delivery apparatus includes a valve carrying member. A prosthetic valve is crimped onto the valve carrying member at a location that is distal or proximal to the balloon member, thereby providing a smaller profile delivery apparatus.Type: GrantFiled: June 10, 2015Date of Patent: October 29, 2019Assignee: Edwards Lifesciences CorporationInventors: Thanh Huy Le, Tri D.
