1. A system for endovascular heart valve repair, the system comprising:
a delivery catheter comprising a retractable sheath and an inner shaft coaxial with the retractable sheath;
a valve assembly having a delivery position and an expanded position, the valve assembly comprising:
a stent having a proximal end and a distal end, the stent having an outer surface and an inner surface defining a stent lumen, the stent having at least one stent locking element; and
a valve having a proximal end and a distal end, the valve having an outer surface and an inner surface defining a valve lumen, the valve further comprising at least one valve leaflet within the valve lumen, a valve body extending from the proximal end and the distal end, a cuff at the distal end of the valve and defining a valve channel between the cuff and the outer surface of the valve body, and at least one valve locking feature for engagement with the stent locking element, wherein the valve locking feature is positioned within the valve channel;
wherein, when the valve assembly is in the delivery position, the valve assembly is disposed between the retractable sheath and the inner shaft, and the proximal end of the valve is positioned distally from the distal end of the stent.
