1. Apparatus, comprising:
a frame assembly that comprises:
a valve body that circumscribes a longitudinal axis and defines a lumen along the axis;
a plurality of upstream arms that are coupled to the valve body at a first axial level with respect to the longitudinal axis, each of the plurality of upstream arms extending radially outward from the valve body to a respective arm-tip; and
a plurality of downstream legs that are coupled to the valve body at a second axial level with respect to the longitudinal axis, and that extend radially outward from the valve body and toward the plurality of upstream arms;
a plurality of prosthetic leaflets, disposed within the lumen, and arranged to facilitate one-way upstream-to-downstream fluid flow through the lumen, the first axial level being upstream of the second axial level; and
a flexible pouch that defines an interior space therein, the pouch shaped and coupled to the frame assembly such that:
the pouch extends radially outward from the valve body, and
the plurality of upstream arms and the plurality of downstream legs narrow the pouch therebetween to form a narrowed portion of the pouch, so as to define:
an inner portion of the interior space, radially inward from the narrowed portion, and in fluid communication with the lumen, and
an outer portion of the interior space, radially outward from the narrowed portion, and in fluid communication with the inner portion via the narrowed portion.
