摘要：
A stent for implantation at a native heart valve includes an expandable body having a first open end and second open end opposite the first open end. The sent includes a plurality of positioning arches positioned around an outer perimeter of the expandable body. Each positioning arch terminates in an apex facing toward the first open end of the expandable body. In an implanted position, the expandable body is oriented such that the first open end is upstream the second open end relative to a direction of blood flow through the native heart valve. In the implanted position, the apex of each of the positioning arches is configured to be positioned within a respective one of a plurality of pockets of the native heart valve and the first open end is positioned upstream of an annulus of the heart valve and out of contact with nerve bundles of the valve.
