Abstract
A repair device for treatment of tricuspid regurgitation includes a support frame, an occlusive membrane, and a suture line. The support frame includes a central shaft and anchoring members that are disposed around the central shaft and radially unfolded for anchoring leaflets of a tricuspid valve. The occlusive membrane surrounds connections between the anchoring members and the central shaft, and the occlusive membrane is connected to the support frame through the suture line. A semi-closed space surrounding the central shaft is formed by an outer side wall of the central shaft, the anchoring members and the occlusive membrane, and has a closed end in proximity to a ventricle and an open end in proximity to an atrium. The central shaft has a closed end in proximity to the ventricle. The repair device for treatment of tricuspid regurgitation reduces the number of implants, thereby reducing the side effects caused by implantation.
