Abstract

A vascular implant, in particular a prosthetic heart valve, for providing valve function, has a stent structure with a proximal conical-convex inflow region, a distal, linear cylindrical outflow region, an intermediate transition region, and a corresponding valve arrangement. When the stent structure is in the expanded state, a higher maximum radial force exists in the inlet region in direct comparison to the lower maximum radial force in the outlet region and in the transition region.
