FIELD: medicine.SUBSTANCE: device contains the main body with the first and second ends. The first and second ends have openings for fluid communication. The membrane element is located inside or on the end of the main body. The membrane element is designed so that it provides the said fluid communication through the main body in the first current direction of and overlaps it in the second current direction. The main body in the first working state is characterized by a larger ratio of length and transverse extent along the longitudinal axis of the main body, and in the second working state - by a smaller ratio. By application of a force acting against the elastic forces of the material, the main body can be reversibly transferred from the secondary form to the primary form. The main body is formed of a single wire type element or of several wire-type elements interconnected by cross-winding and/or twisting, and/or fabric-type weaving and/or multi-layer structure weaving and/or mesh weaving. One anchoring section in the second operating state of the main body has the first part of the section and the second part of the section. The first part extends radially outwards from the main body and the second part of the section is bent radially inwardly and/or outwardly of the main body so that the first part of the section and the second part of the section are stacked on top of each other in two layers.EFFECT: invention allows to exclude damage to the device elements.50 cl, 36 dwgИзобретение касается имплантируемого устройства для замены клапана органа. Устройство содержит основное тело с первым и вторым концами. Первый и второй концы имеют отверстия для сообщения по текучей среде. Мембранный элемент расположен внутри или на конце основного тела. Мембранный элемент выполнен таким образом, что он обеспечивает указанное сообщение по текучей среде через основное тело в первом направлении тока и перекрывает его во втором направлении тока. Основное тело в первом рабочем сост
