  • VENTRICULAR DEPLOYMENT OF A TRANSCATHETER MITRAL VALVE PROSTHESIS
    Publication number: 20230380965
    Abstract: A method of delivering a prosthetic valve to a native mitral valve of patient's heart may include providing a radially expandable prosthetic mitral valve which has an upstream atrial portion, a downstream ventricular portion and an annular region therebetween. A constraint is removed from the ventricular portion thereby allowing radial expansion of a ventricular portion. A first anchoring tab on the ventricular portion is radially expanded and an annular region is radially expanded. An atrial skirt on the atrial flange is radially expanded after radial expansion of the ventricular portion.
    Type: Application

  • PROSTHETIC VALVE WITH NATURAL BLOOD FLOW
    Publication number: 20230100125
    Abstract: A prosthetic valve may be formed to direct flow out of the outflow orifice toward a posterior portion of a heart wall. The prosthetic valve includes an expandable frame which may be covered with a cover that is suturelessly attached to the frame. The prosthetic valve may also include an outflow orifice size which is controlled. Methods of using these devices are also disclosed.
