a multi-part frame defining a flow lumen through which fluid is able to selectively flow, the multi-part frame including,
an outer support portion having a generally tubular shape defining a first lumen,
an evertible support portion having a generally tubular shape, and

a flexible bridge material coupling the evertible support portion to the outer support portion, such that the evertible support portion is transitionable from a first, laterally adjacent position relative to the outer support portion and a second, everted position in which the evertible support portion is at least partially located within the first lumen of the outer support portion; and
a plurality of leaflets coupled to the multi-part frame, each leaflet being moveable between an open position and closed position to selectively block and unblock the flow lumen of the multi-part frame when the transcatheter valve is in an expanded configuration;
