THE DOUBLE-SHEET STENT

摘要

This invention is the 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 said 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 said winding outlines is executed by a simple superimposing of the stencil I winding outline (12) on the stencil II winding outline (14), whereas the said 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.
