1. A valve for implantation within a body lumen, comprising:

  • an elongate valve frame configured to shift between a collapsed configuration and an expanded configuration, wherein the valve frame is configured to exert a radially outward force against a wall of the body lumen in the expanded configuration;

    wherein the valve frame includes an inner frame portion and an outer frame portion;

    a first valve leaflet and a second valve leaflet attached to the inner frame portion and defining a lumen through the valve, the first and second valve leaflets having an open configuration configured to permit flow of a bodily fluid therethrough and a closed configuration configured to restrict flow of the bodily fluid therethrough;

    wherein the inner frame portion defines a cross-sectional area of the valve relative to a central longitudinal axis of the lumen having a circular shape in the expanded configuration;

    wherein the outer frame portion defines a cross-sectional area of the valve relative to the central longitudinal axis of the lumen having an ovoid shape in the expanded configuration wherein the ovoid shape is defined by a first dimension and a second dimension each measured perpendicular to the central longitudinal axis of the lumen through the valve, wherein the first dimension is greater than the second dimension;

    wherein the outer frame portion defines a sinus pocket.
