Abstract
A transcatheter prosthesis includes a stent, a prosthetic valve component, and an anti-paravalvular leakage component. The anti-paravalvular leakage component is coupled to the stent and includes an inner skirt, an outer wrap, a cavity, an opening, and a one-way valve. The inner skirt is disposed on an inner surface of the stent and has an inflow end and a downstream end. The outer wrap is disposed around an outer surface of the stent and has an inflow end coupled to the inflow end of the inner skirt and a downstream end. The cavity is formed between an outer surface of the inner skirt and an inner surface of the outer wrap. An opening is disposed between the inner skirt and the outer wrap. The one-way valve includes a flap at the opening configured to open to allow blood flow into the cavity but prevent blood flow out of the cavity.
