Abstract: An implantable PROSTHESIS with formed power couch+, including a primary tube as an half finished product in a form of an additional support stent, the additional support stem forms a circular structure upon its expansion that allows to reduce the total mass of the implantable valve device upon keeping of its high dynamics stability and to establish axis-symmetrical shape similar to hyperboloid. The leaflets of a valve device functional part are provided a system of a low-profile guiding spiral relief, under which blood flow imposes additionally a component of a spiral movement.
