Publication number: 20240138986Abstract: A valve repair device, e.g., for treating mitral valve regurgitation, includes a tubular body defining a longitudinal axis, paddles supported by the tubular body and movable to change abduction of the paddles relative to the longitudinal axis, and retention members supported by the tubular body proximal the paddles and similarly movable to change abduction of the retention members relative to the longitudinal axis to facilitate capture of native valve leaflets between pairs of paddles and retention members. Movement of the paddles and/or retention members is provided by one or more control mechanisms including a collar a shaft extending within the tubular body. Each shaft is threadedly engaged to a respective collar and coupled to one or more of the movable elements such that, when the collar is rotated, the shaft translates to change abduction of the movable element relative to the longitudinal axis.Type: ApplicationFiled: April 11, 2023Publication date: May 2, 2024Applicant: Capstan Medical Inc.Inventor: Daniel T.
