Abstract

Устройство и способ удаления тромбов предназначены для восстановления кровотока и удаления тромбов из просвета кровеносных сосудов, в частности закупоренных мозговых артерий. Техническим результатом заявленного изобретения является увеличение точности, скорости и эффективности извлечения тромбов из кровеносных сосудов головного мозга без разрушения тромба, снижение травмоопасности устройства для сосудов, снижение вероятности нарушения целостности устройства во время операции по удалению тромба. Технический результат достигается тем, что устройство для удаления тромба содержит саморасширяющуюся сетчатую структуру и толкатель, соединенные посредством прочного и безопасного соединения, снижающего вероятность отрыва сетчатой структуры от толкателя и позволяющего более уверенно извлекать из тела пациента интегрированную массу, состоящую из сетчатой структуры и тромба; а также тем, что дистальные рентгеноконтрастные метки устройства, необходимые для визуализации правильного размещения устройства в сосуде, покрыты рентгеноконтрастным связующим агентом, который имеет гладкую поверхность, что способствует безопасности, точности и скорости проводимых манипуляций.The device and method for removing blood clots are designed to restore blood flow and remove blood clots from the lumen of blood vessels, in particular clogged cerebral arteries. The technical result of the claimed invention is to increase the accuracy, speed and efficiency of removing blood clots from the blood vessels of the brain without destroying the blood clot, reducing the risk of injury of the device for blood vessels, reducing the likelihood of violation of the integrity of the device during the operation to remove the clot. The technical result is achieved in that the device for removing a thrombus contains a self-expanding mesh structure and a pusher, connected by a strong and secure connection, which reduces the likelihood of detachment of the mesh structure from the pusher and allows more confidently removing from the patient's body an integrated mass consisting of a mesh structure and a thrombus; and also by the fact that the distal radiopaque marks of the device, necessary for visualizing the correct placement of the device in the vessel, are coated with a radiopaque binding agent that has a smooth surface, which contributes to the safety, accuracy and speed of the manipulations.
