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.

Abstract: A double-sheet stent for insertion into a lumen of a vessel of living being, comprises constructive elements, preliminary formed in a shape of the two mainly similar stencils I and II on the surface of the two thin sheet metallic blanks. The stencils I and II are preliminary superimposed one on another in order to be shifted for a winding outline width along the stent longitudinal axis and to form the alternating winding outlines pairs. One pair of the winding outlines is executed by a simple superimposing of the stencil I winding outline (12) on the stencil II winding outline (14), whereas the winding outlines pair, neighboring to it, is performed by the superimposing of the stencil II winding outline (15) on the stencil I winding outline (13). The stencil II winding outlines are passed through the slots between the stencil I winding outlines as to make the formed semicircles be located in turns in the stent expanded shape.
