  • Publication number: 20230263627
    Abstract: A growth-accommodating prosthetic valve system that can accommodate a patient's growth over time. The system features an expandable stent that can expand from a contracted configuration to an expanded configuration and leaflets attached to the scaffold that is sewn along a path such that the length of the path stays generally the same as the scaffold moves from the contracted configuration to the expanded configuration.

  • Publication number: 20220273434
    Abstract: The present invention is directed to a device for first grabbing, and then securing the native atrioventricular valve's leaflet to a prosthesis via transcatheter means. The present invention features a grasping device for securing a leaflet component of a native mitral valve. The leaflet component comprises a leaflet and chordae tendineae associated with the. In some embodiments, the device may comprise a first grasping component configured to grab chordae tendineae of said native mitral leaflet component, and a second grasping component configured to anchor the native mitral leaflet component to a prosthetic component. In some embodiments, the first grasping component may comprise at least one grasping arm configured to transition from a non-extended state to an extended state to a grasping state. In some embodiments, the second grasping component may comprise a hook disposed at a distal end of the device capable of anchoring to the prosthetic component.

  • Publication number: 20210137676
    Abstract: Disclosed herein is a valve system with an original deployed diameter that is suitable for a child and/or young adult and that can accommodate the patient's growth by a one-time balloon expansion to attain an expanded diameter in that patient. This novel valve addresses an unmet need for children with valve dysfunction and to stop valve-related progressive ventricular dysfunction, and ultimately avoid heart failure in children and young adults.
