  • Mitral valve prosthesis implantation
    Patent number: 11207177
    Abstract: A heart valve prosthesis and methods of its implantation are described herein. The prosthesis can be implanted in a heart of a patient by positioning an upper support of an anchoring element into a left atrium of the patient. The upper support can expand adjacent to a native valve structure of the patient. Further, the upper support can be moved against the native valve structure in a direction toward a left ventricle of the patient. A lower support of the anchoring element can be positioned into the left ventricle, spaced apart from the upper support, the lower support being separate from the upper support and coupled to the upper support by a flexible connector. Finally, the lower support can expand within the left ventricle, and engagement members of the lower support can engage with tissue of the native valve structure.

  • THERMOSTAT WITH A PLURALITY OF RANKED LEVELS OF ACCESS CONTROL
    Publication number: 20210400034
    Abstract: A system and method for configuring an HVAC thermostat provides multiple users of varying rank with different levels of permission to access different sets of thermostat functions. The thermostat distinguishes users by the passcodes they enter. In some examples, a cascade hierarchy enables multiple levels of higher ranking users to limit the function accessibility of lower ranking users. In some examples, higher ranking users determine which home screen is presented to users that do not enter a passcode.

  • PROSTHETIC HEART VALVE DELIVERY
    Publication number: 20210353413
    Abstract: A prosthetic heart delivery assembly can provide dynamic control of the components of a valve prosthesis during delivery and placement at a target site. The assembly can permit expansion of a valve anchor and thereafter permit adjustment of the position of the valve anchor using a position control element and/or via a link mechanism coupled to a valve frame of the prosthesis. The assembly can therefore allow a surgeon to adjust the prosthesis's position in both longitudinal and rotational directions at the target site.

  • VALVE-IN-VALVE DELIVERY OF A HEART VALVE PROSTHESIS
    Publication number: 20210353414
    Abstract: A replacement heart valve prosthesis can be delivered to or within an existing prosthesis through a valve-in-valve delivery procedure. The existing prosthesis can be a prosthetic heart valve or other device that is implanted at a target site, such as an aortic or mitral valve of the heart. The methods provided herein can allow a surgeon to position a replacement prosthesis within or adjacent to an existing prosthesis and permit the replacement prosthesis to expand into engagement against the existing prosthesis. Thereafter, the surgeon can adjust components of the replacement prosthesis, including the position of separate anchor and frame components in order to ensure accurate and secure placement of the replacement prosthesis at the target site.
