  • Publication number: 20240081987
    Abstract: Aspects of the disclosure relate to prosthetic valves having a frame, a frame cover, and a leaflet construct. Some aspects are directed to a diametric taper for the prosthetic valve for achieving enhanced performance of the prosthetic valve under operational conditions, enhanced compressibility and delivery characteristics, and other additional or alternative advantages. Other aspects are directed toward unique assembly and attachment methods for securing leaflet constructs to support structures. Other aspects are directed toward features for interacting with transcatheter delivery systems. Still other aspects are directed to such apparatuses, systems, and methods for valve replacement, such as cardiac valve replacement.

  • Publication number: 20210005021
    Abstract: A mixed reality display system determines a shared coordinate system that is understood by a mixed reality application running on the mixed reality display system and an operating system of the mixed reality display system. The operating system can display a system user interface (UI) element in a mixed reality environment. The system UI element can be displayed at a location in a mixed reality environment. The location is specified by the mixed reality application according to the shared coordinate system. A size and orientation for displaying the system UI element may also be specified. Also, the location, size and orientation may be specified through application program interfaces (API) of the operating system. API calls may be made per frame to adjust the location, size or orientation per frame of the displayed mixed reality environment.
