1. A prosthetic heart valve device comprising:

  • an expandable inner frame having a first end region and a second end region, the inner frame comprising a generally tubular body portion having an inner surface and an outer surface;

    an expandable outer frame having a first end region and a second end region, the outer frame comprising a generally tubular body portion having an inner surface and an outer surface, the outer frame comprising a plurality of interconnected closed cells extending circumferentially around the inner frame, wherein the inner surface of the outer frame is spaced from the outer surface of the inner frame;

    a connection structure extending between and connecting the second end region of the outer frame to the second end region of the inner frame, wherein the connection structure is configured to allow movement of the outer frame relative to the inner frame;

    a valve member attached to the inner frame;

    wherein the first end region of the outer frame is mechanically isolated from the first end region of the inner frame such that the first end region of the inner frame is configured to maintain a cross-sectional shape while the first end region of the outer frame deforms from a first cross-sectional shape into a second cross-sectional shape.
