  • EXPANDABLE VALVE PROSTHESIS WITH SEALING MECHANISM
    Publication number: 20210196458
    Abstract: A prosthetic heart valve includes at least one sealing member. The sealing member is adapted to conform to any surface irregularities found on the inner surface of the valve annulus, including any calcium deposits formed on the valve leaflets. The sealing member can be self-expanding or non-expanding. When deployed, the sealing member is adapted to create a blood tight seal between the prosthetic heart valve and the inner surface of the valve annulus thereby minimizing and/or eliminating perivalvular leakage at the implantation site.
    Type: Application

  • MICROPROCESSOR CONTROLLED DELIVERY SYSTEM FOR CARDIAC VALVE PROSTHESIS
    Publication number: 20090105794
    Abstract: An instrument for deploying a cardiac valve prosthesis, including a plurality of radially expandable portions, at an implantation site, includes a plurality of deployment elements each independently operable to obtain the radial expansion of a radially expandable portion of the valve prosthesis. The instrument includes a microprocessor configured to processes signals from one or more sensors and to optimize deployment of the valve prosthesis.
