  • Protected adjustable heart valve sizer
    Patent number: 11957587
    Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.
    Type: Grant
