Abstract
A medical implant may include an expandable anchor member having a lumen extending through the expandable anchor member from an inflow end to an outflow end; a plurality of valve leaflets disposed within the lumen extending through the expandable anchor member; a seal member disposed adjacent an exterior of the expandable anchor member; and a porous material extending from the seal member to the plurality of valve leaflets.
Claims20
A medical implant, comprising:
- an expandable anchor member having a lumen extending through the expandable anchor member from an inflow end to an outflow end;
- a plurality of valve leaflets disposed within the lumen extending through the expandable anchor member, the plurality of valve leaflets configured to move between an open configuration and a closed configuration;
- a seal member disposed adjacent an exterior of the expandable anchor member;
- and
- a porous material extending from the seal member to the plurality of valve leaflets, the porous material configured to allow fluid flow therethrough while the plurality of valve leaflets are in the closed configuration.
