Publication number: 20230240845Abstract: A transfemoral delivery system for implanting a replacement heart valve is provided. The replacement heart valve includes an expandable frame and a plurality of distal anchors. The delivery device includes an outer sheath assembly, a mid-shaft assembly, and an inner assembly, wherein the outer sheath assembly and the mid shaft assembly retain the replacement heart valve in a radially compacted state. The outer sheath assembly is retracted relative to the mid-shaft assembly to release the distal anchors while a portion of the replacement heart valve remains retained by the mid shaft assembly. After the distal anchors engage leaflets of the native heart valve, the retained portion of the replacement heart valve is released from the mid-shaft assembly and is allowed to fully expand.Type: ApplicationFiled: April 7, 2023Publication date: August 3, 2023Inventors: Glen T. Rabito, J. Brent Ratz, Arshad Quadri, Lindsay Lam, David Robert Landon, Garrett Dallas Johnson

Patent number: 11633279Abstract: Methods for delivering a replacement heart valve include advancing a delivery system through a femoral vein and into the atrium of a heart, wherein the delivery system includes an outer sheath assembly, a mid shaft assembly and an inner assembly. The outer sheath assembly and the mid shaft assembly are adapted to retain the replacement heart valve in a radially compacted state over the inner assembly. The outer sheath assembly is retracted to allow a plurality of distal anchors to self-expand while a portion of the replacement heart valve remains retained in a compacted state by the mid shaft assembly. The distal anchors are positioned to engage one or more native leaflets and the retained portion of the replacement heart valve is then released and allowed to fully expand for implanting the replacement heart valve within the native valve.Type: GrantFiled: March 19, 2021Date of Patent: April 25, 2023Assignee: Edwards Lifesciences CardiAQ LLCInventors: Glen T. Rabito, Jeremy Brent Ratz, Arshad Quadri, Lindsay Lam, David Robert Landon, Garrett Dallas Johnson
