  • Publication number: 20220273427
    Abstract: Some embodiments described herein include a heart valve replacement system that may be delivered to the targeted heart valve site via a delivery catheter. In some embodiments, the heart valve replacement system can assemble a valve device after the valve device is delivered to the heart. In some embodiments, heart valve replacement system includes two anterior flaps that are separate but overlap each other.

  • Publication number: 20220226105
    Abstract: A method of delivering a valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The method including collapsing a prosthetic valve having an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough inside of a delivery instrument, such that a plurality of spaced anchors extending from the distal end of the expandable frame towards the proximal end are collapsed to an inverted position in a collapsed anchor configuration. The method further including advancing the delivery instrument a first distance such that the plurality of spaced anchors extend below the valve annulus, and releasing each of the plurality of spaced anchors such that each of the plurality of spaced anchors is repositioned from the inverted position to an expanded anchor configuration to contact a subannular location.

  • Publication number: 20220226106
    Abstract: Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. In some embodiments, composite two-portion prosthetic heart valves in which two expandable components are attached to each other can be arranged in a nested configuration during both the transcatheter delivery process and the deployment process within the heart. Deployment systems and methods for using the deployment systems described herein facilitate implanting the composite two-portion prosthetic heart valves that are attached and arranged in a nested configuration during the transcatheter delivery and deployment processes.

  • Publication number: 20220202567
    Abstract: A valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The valve prosthesis including an expandable frame and a plurality of spaced anchors. The expandable frame includes a proximal end and a distal end and a longitudinal axis extending therethrough. The expandable frame collapses radially for delivery and expands radially upon deployment to an expanded configuration. The plurality of spaced anchors extend from the distal end of the frame towards the proximal end, each anchor formed with a free end, and each anchor being expandable from a collapsed anchor configuration to an expanded anchor configuration, wherein each of the anchors includes a foot angle of from 0 to 45 degrees relative to the longitudinal axis.
