摘要：
FIELD: medicine.SUBSTANCE: group of inventions relates to medicine, restoring blood flow in occluded vessels with application of device, which contains self-expansible distal element (SDE) with tube structure (TS), which possesses cells. TS can take configuration with increased volume in place of thrombus location in vessel and turn into configuration with reduced volume to be delivered through microcatheter. Configuration with reduced volume has size of transverse profile smaller than configuration with increased volume. TS has possibility of expansion from configuration with reduced volume into configuration with increased volume in case of proximal removal of microcatheter. Distal end of TS interacts and renders radial force impact on at least part of thrombus in order to connect it with TS. Device in addition contains proximally elongated element (PEE), fastened to SDE in such a way, that PEE as a whole is located parallel to central longitudinal axis of TS with displacement relative to said axis. Cellular structure of TS represents connection of bridges, threads or bonds. Distal element has conical structure in its proximal end, where bridges, threads and bonds diverge in connective point. Distal part of distal end of tube structure contains cells, whose size is smaller than size of cells, located proximally relative to distal part.EFFECT: application of claimed device ensures high speed and efficiency of revasculisation of brain arteries, occluded with thrombus.26 cl, 19 dwgГруппа изобретений относится к медицине, восстановлению кровотока в закупоренных кровеносных сосудах с применением устройства, содержащего саморасширяемый дистальный элемент (СДЭ) с трубчатой структурой (ТС), имеющей ячейки. ТС может принимать конфигурацию с увеличенным объемом в месте расположения тромба в сосуде и переходить в конфигурацию с уменьшенным объемом для подачи через микрокатетер. Конфигурация с уменьшенным объемом имеет размер поперечного сечения меньше, чем конфигурация с у
