摘要：
The invention relates to medicine, in particular vascular surgery, and can be used to maintain the lumen of the blood, including coronary, vascular or hollow organ.The technical result of the utility model is to increase the design flexibility of the stent by the use of the open geometry of the cell, as well as improving the biocompatibility and thromboresistance designs through the use of the carbon coating and the creation of the directed output pharmacological preparation in the vessel wall by the presence of troughs in each cell of the rack, and reducing the likelihood of restenosis through the use of an active coating on the side of a stent, facing a vessel lumen.The stent 1 is made of a superelastic alloy or a shape memory material, such as titanium nickel alloy or cobalt-chromium alloy. A stent is a mesh tube, each cell 2 is an open structure. At the ends of the stent 1 arranged roentgenopaque tags 4. The entire surface of the stent is coated with a carbon layer 5 to reduce the risk of thrombus formation and improve biocompatibility structure. On the central part of the beam of each cell passes trough 6 filled with a drug coating. This chute 6 is turned to the outside from the central longitudinal axis of the stent 1 for directional output of pharmacological preparation in the vessel wall. The inner surface of the stent 1, facing the lumen of the vessel is covered with polymer 7 comprising a bioactive component that promotes endothelialization structure.3 z.p.f., 3 ill.Полезная модель относится к медицине, в частности к сосудистой хирургии, и может быть использована для поддержания просвета кровеносного, в том числе и коронарного, сосуда или полого органа.Техническим результатом полезной модели является повышение гибкости конструкции стента за счет использования открытой геометрии ячейки, а также повышение биосовместимости и тромборезистентности конструкции за счет использования углеродного покрытия, а также создание направленного выхода фармакологического пр
