Publication number: 20230404753Abstract: A delivery system includes a suture attachment mechanism for maintaining a connection to a heart valve after initial deployment, thereby allowing recapture of the heart valve if desired. A plurality of suture portions is provided along a distal end portion of the delivery system, each suture portion having a first end fixed to the delivery system and a second end releasably coupled to a retention member on the delivery system. A knob on a handle of the delivery system is actuated for causing the second end of each suture portion to be released from its respective retention member, thereby allowing the suture portions to be decoupled from the heart valve. The suture portions are located only along a distal end portion of the delivery system for improving reliability and consistency.Type: ApplicationFiled: August 7, 2023Publication date: December 21, 2023Inventors: Hieu Minh Luong, Julio Cesar Sanchez, Alexander H.

Patent number: 11833040Abstract: Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.Type: GrantFiled: May 26, 2022Date of Patent: December 5, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: David Robert Landon, Glen T.

Publication number: 20230218391Abstract: A prosthetic heart valve for deployment in a native heart valve. The prosthetic heart valve includes an inner frame and a plurality of anchors extending from a distal portion of the inner frame. An outer sealing frame is positioned radially outward of the inner frame. The distal end portion of the outer frame is attached to a distal portion of the inner frame by a flexible cloth material such that the outer frame can move axially or tilt with respect to the inner frame. The anchors are shaped to capture native leaflets between the anchors and the outer frame to secure the prosthetic valve in the native heart valve. Prosthetic valve leaflets are provided in a lumen of the inner frame for allowing one way flow through the prosthetic valve, thereby replacing the function of the native heart valve.Type: ApplicationFiled: March 6, 2023Publication date: July 13, 2023Inventors: Ajay Kumar Dass, David Robert Landon, Taylor Jacob Scheinblum, Hieu Minh Luong

Publication number: 20220006850Abstract: A method for replacing a native heart valve includes advancing a delivery catheter having a valve prosthesis disposed along a distal end portion thereof, wherein the valve includes an inner frame having an hourglass shape and an outer sealing frame connected to and surrounding the inner frame. A valve body is mounted within the inner frame and includes a plurality of leaflets. The leaflets have longitudinal curvatures when in an open position, wherein the curvatures are shaped for conforming to the curved interior surface of the inner frame. This combination of features reduces the possibility of blood stagnating between the leaflets and inner frame, which reduces the possibility of thrombus formation.Type: ApplicationFiled: July 28, 2021Publication date: January 6, 2022Applicant: Edwards Lifesciences CorporationInventors: Alexander H.

Patent number: 11051934Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.Type: GrantFiled: February 26, 2019Date of Patent: July 6, 2021Assignee: Edwards Lifesciences CorporationInventors: Alexander H.
