Patent number: 11510794Abstract: Disclosed herein is a method of crimping a prosthetic heart valve using a compact crimping mechanism. The crimping mechanism includes a plurality of jaws configured for coordinated inward movement toward a crimping axis to reduce the size of a crimping iris around a stented valve. A rotating cam wheel acts on the jaws and displaces them inward. A number of Cartesian guide elements cooperate with the jaws to distribute forces within the crimping mechanism. The guide elements are located between the crimping jaws and an outer housing and are constrained by the outer housing for movement along lines that are tangential to a circle centered on the crimping axis. The guide elements engage at least some of the crimping jaws while the rest are in meshing engagement so as to move in synch. An actuation mechanism includes a lead screw, carriage assembly and a linkage to rotate the cam wheel with significant torque.Type: GrantFiled: July 21, 2020Date of Patent: November 29, 2022Assignee: Edwards Lifesciences CorporationInventors: Tomer Saar, Gregory Rinberg

Publication number: 20210282922Abstract: A radially expandable prosthetic valve can comprise an annular frame, at least one expansion mechanism and a cord. The annular frame can be radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The expansion mechanism can comprise a first member attached to the frame at a first location and a second member attached to the frame at a second location axially spaced from the first location. The cord can extend at least partially along the expansion mechanism in a first direction, be reeved around a portion of the second member, and extend at least partially along the expansion mechanism in a second direction opposite the first direction. Applying a proximally directed force to a first portion of the cord can cause the second member to move relative to the first member, which can cause the frame to foreshorten axially and expand radially.Type: ApplicationFiled: June 3, 2021Publication date: September 16, 2021Applicant: Edwards Lifesciences CorporationInventors: Hanoch Cohen-Tzemach, Tamir S.
