Title:
REPAIR DEVICE FOR PREVENTING VALVE REGURGITATION
Document Type and Number:
WIPO Patent Application WO/2022/267851
Kind Code:
A1
Abstract:
A repair device for preventing valve regurgitation, comprising: a mounting bracket (1); and a single anti-regurgitation valve leaflet prosthesis (2) used for replacing the function of a single autologous valve leaflet, one end of the single anti-regurgitation valve leaflet prosthesis (2) being fixed on the mounting bracket (1). The repair device only replaces a faulty single valve leaflet, thereby retaining the original functions of the remaining autologous valve leaflets, without changing the shape of an autologous valve ring; therefore, the damage to intracardiac tissue is small, and moreover, the number of implants is relatively low, and the irritation is small.
