Abstract
A transcatheter valve prosthesis includes a stent and a prosthetic valve. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members extending between the inflow portion and the outflow portion. Each axial frame member extends in an axial direction from a crown of the inflow portion to at least a crown of the outflow portion. Each axial frame member has a first end adjacent to the crown of the inflow portion, the first end having a reduced width relative to a width of a length of the axial frame member between the first end and the crown of the outflow portion.
