Patent number: 11957587Abstract: 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: GrantFiled: November 8, 2021Date of Patent: April 16, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Gerald B. Gollinger, William A. Maywald, Derrick Johnson, Brian S. Conklin, Ankita Bordoloi Gurunath, Da-Yu Chang
