Stent for the positioning and anchoring of a valvular prosthesis in an implantation site in the heart of a patient
First Claim
3-1. The expandable stent according to claim 1, further including a collapsed mode when being introduced into a patient'"'"'s body and an expanded mode when implanted, wherein the at least one radial arch is configured to press against a vascular wall with a radially-acting force so as to anchor said stent when the stent is in the expanded mode.
