Patent number: 11903827Abstract: This document provides devices and methods for the treatment of heart conditions. For example, this document provides prosthetic heart valves and transcatheter heart valve replacement methods. The prosthetic heart valves can be configured into a low-profile configuration for containment within a small diameter delivery sheath. The prosthetic heart valves include can include a valve member attached to a stent frame. In some embodiments, the valve member is a molded biomaterial with a novel shape and resulting performance characteristics. Localized protective covering members can be attached to the stent frame to prevent the valve member from contacting the stent frame as the valve member cycles between its open and closed configurations.Type: GrantFiled: April 10, 2023Date of Patent: February 20, 2024Assignee: Anteris Technologies CorporationInventors: Jason Quill, William Leon Neethling, Christopher B. Brodeur, Ramji Iyer, Kaitlyn Roth

Patent number: 11883286Abstract: A replacement heart valve prosthesis is loaded onto a balloon mounted onto a balloon shaft of a catheter system. The balloon shaft is rotatably engaged with an actuator on the handle of the catheter system. Rotation of the actuator by a first amount in a first direction permits rotation of the heart valve prosthesis by a known amount during the procedure so that alignment of the commissures of the replacement valve with the commissures of the existing valve can be predictably achieved.Type: GrantFiled: February 1, 2023Date of Patent: January 30, 2024Assignee: Anteris Technologies CorporationInventors: Jason L. Quill, Dannah Dean, Cameron James Albin Murto, Edward James Anderson, Brad James Traeger, Payton Kristine Parmett, Nicholas Weldon Pensa, Joseph Allen Duerr

Patent number: 11877927Abstract: A replacement heart valve prosthesis for transcatheter repair of a native valve, the replacement heart valve comprises a valve construct mounted to the exterior surface of an expandable frame. The frame comprises an expandable region near the distal end of the frame, and a cusp region near the proximal region comprising a plurality of valve attachment features. The valve construct may be attached to the valve construct at least at the valve attachment features. The replacement heart valve prosthesis of present disclosure may be a more durable and long-lasting valve that has added benefits by placing valve tissue between the expandable frame and native cardiac tissue.Type: GrantFiled: January 6, 2023Date of Patent: January 23, 2024Assignee: Anteris Technologies CorporationInventors: Ramji Iyer, David Lawrence St. Denis, Jr., Samuel Thomas Johnson, William Morris Leonard Neethling, Martha Jeanne Engel
