FIELD : medicine.SUBSTANCE : group of inventions relates to medicine, in particular, to a stent for mounting into a patient' s body, in which the areas of cells are coated with a functional material coating, wherein said functional material is a polymer selected from a group consisting of gelatin, polyglycolic acid/polylactic acid, polycaprolactone, polyhydroxybutyrate/valerate, polyorthoester, polyethylene oxide/polybutylene terephthalate, polyurethane, polydimethylsiloxane, silicone, polyethylene terephthalate, polytetrafluoroethylene and foamed polytetrafluoroethylene, in which the volume of the coating in the cell area is given by equation (1) : Vsa=Asa譴scx, where Vsa is the averaged volume of the stable coating per one unit, which is understood as interweaving or crossing of stent elements, Asa is the averaged area of the stable section of the coating per one unit, lscx is the cell stable axial length; and to the stent, in which the cell area coverage volume is given by equation (20) : V=2R?lcx-2R)議, where R is the cell axial end radius, lcx is the cell axial length, h is the cell thickness or height.EFFECT : group of inventions provides an improved radiopacity effect as compared to existing stents and promotes stable arrangement of relatively large amounts of functional drug preparations.16 cl, 40 dwg, 1 ex
