Abstract
The invention relates to prosthetic heart valves comprising a stent frame with valve support disposed or inverted at least partially within the stent frame, wherein the valve support is at least partially within the interior of the stent frame. The inverted configuration comprises a maximum number of layers of material in cross section where the stent frame and valve support overlap. The maximum number of cross-sectional layers of material structure may be reduced to, e.g., two layers of material to reduce outer diameter during delivery by everting the valve portion to a position located outside of the stent portion, followed by inverted reconfiguration back to the inverted anchoring structure after delivery from the lumen of the delivery catheter to the heart chamber.
