Abstract
The present disclosure relates to prosthetic valves configured to allow or encourage tissue adherence to polymeric surfaces of valvular structures thereof. In an example, a prosthetic valve can include a frame movable between a radially compressed state and a radially expanded state, and a valvular structure mounted inside the frame, the valvular structure comprising a plurality of leaflets. Each leaflet comprises a leaflet polymeric inner surface facing a central longitudinal axis of the prosthetic valve, and a leaflet polymeric outer surface facing the frame, wherein at least one of the polymeric surfaces of the leaflet comprises a tissue-adherent surface, configured to allow tissue adherence thereto.
Claims21
A prosthetic valve comprising:
- a frame movable between a radially compressed state and a radially expanded state;
- a valvular structure mounted inside the frame and comprising a plurality of leaflets, wherein each leaflet comprises a cusp edge, a free edge opposite to the cusp edge, and leaflet polymeric surfaces extending between the cusp edge and the free edge, the leaflet polymeric surfaces comprising:
- a leaflet polymeric inner surface, facing a central longitudinal axis of the prosthetic valve;
- and
- a leaflet polymeric outer surface, facing the frame;
- wherein at least one of the leaflet polymeric surfaces comprises at least one tissue-adherent surface configured to allow tissue adherence thereto.
