  • Low profile prosthetic mitral valve
    Patent number: 11931254
    Abstract: A low-profile prosthetic valve for treating a native valve includes a radially expandable frame having an expanded configuration and a collapsed configuration. The atrial end of the prosthetic valve forms a flared shape that engages an atrial surface of the native valve. The flare shape flares downward toward a ventricle of the native valve when initially expanded followed by inversion of the flared shape to form a tapered shape tapering toward the ventricle and flaring toward the atrium of the native valve when fully expanded. The prosthetic valve also has a plurality of prosthetic valve leaflets that open and close to control fluid flow through the prosthetic valve.
    Type: Grant
    Filed: March 14, 2022
    Date of Patent: March 19, 2024
    Assignee: Neovasc Tiara Inc.
