1. A prosthetic device for a mitral valve comprising:

  • a longitudinal axis;

    an insert member including an inner support layer and an outer layer, the inner support layer comprising a shape-memory metal, the outer layer comprising fabric,an inflow end, and an outflow end, the longitudinal axis passing through the inflow end and the outflow end,a passageway extending through the insert member along the longitudinal axis, anda one-way valve disposed within the passageway, the one-way valve including one or more flaps, the one-way valve permitting blood flow from the inflow end to outflow end, whereinthe insert member in the compressed state has a diameter suitable for delivery in a delivery sheath,the insert member has an expanded state and a compressed state,the insert member in the expanded state has a cross-sectional profile transverse to the longitudinal axis in which sides of the insert member are shaped for creating a tight seal against native mitral valve leaflets, the insert member in the expanded state sufficiently rigid to substantially maintain a shape thereof; and

    an anchoring member extending longitudinally from the insert member, the anchoring member including a proximal end portion and a distal end portion, the proximal end portion coupled to the insert member, the distal end portion of the anchoring member including a self-expanding, flower-shaped anchor having a compressed configuration and an expanded configuration, the flower-shaped anchor suitable for anchoring to a left ventricular wall.
