Claims20
A replacement heart valve frame assembly, comprising:
- an expandable framework;
- and
- an outer skirt coupled to an outer surface of the expandable framework, the outer skirt having a plurality of pleats.
A replacement heart valve frame assembly comprising:
- an expandable framework comprising a plurality of struts defining a lattice structure having a central lumen, the plurality of struts defining a plurality of lower crowns defining an inflow end of the lattice structure, a plurality of upper crowns proximate an outflow end of the lattice structure, and a plurality of stabilization arches extending downstream from the outflow end of the lattice structure;
- and
- an outer skirt disposed on an outer surface of the lattice structure, the outer skirt having a closed upstream end fixed to the lattice structure, the outer skirt having a free edge forming a single circumferential opening between the expandable framework and an inner surface of the outer skirt, the free edge facing the outflow end of the lattice structure, wherein a diameter of the free edge of the outer skirt is larger than a diameter of the expandable framework.
A method of manufacturing a replacement heart valve frame assembly, comprising:
- providing a frame;
- and
- coupling an outer skirt to the frame, wherein the outer skirt includes a plurality of vertical pleats.
