Description

Изобретение относитс  к медицине, а именно к сосудистой хирургии и нейрохирургии , и предназначено преимущественно .цл  закупорки просвета пато логических сосудов головного мозга. Известно окклюзирующее устройство которое состоит из эластичного баллона с самозат гивакадимс  отверстием в проксимальном конце и катетера, временно вставленного в это отверстие Рабоча  часть катетера (соедин юща с  с баллоном) выполнена с уменьшенным по диаметру участком и расширенной сферической головкой, благодар , чему обеспечиваетс  мобильность проведени  баллона при установке его в заданном отделе сосуда и предотвращаетс  срыв баллона с катетера током крови il. Однако это устройство трудно проводить по извитым и разветвленным кровеносным сосудам, так как при введении баллона в кровеносный сосуд ламинарный поток крови смен етс  на тур булентный. Баллон, закрепленный на уточненном рабочем конце катетера, на чинает вибрировать относительно продольной оси сосуда. Баллон становитс  неуправл емым, его невозможно ввести в извитый, ответвленный от 00ионного сосуда патологический сосуд. При этом баллон может стать поперек аосуда, петлеобразно изогнув утонченную рабочую часть катетера, что не только делает невозможным дальнейшее продвижение баллона по сосуду; но и затрудн ет его обратное удаление из сосуда. Цель изобретени  - обеспечение возможности проведени  баллона по извилистым и разветвленным кровеносным сосудам. Указанна  цель достигаетс  тем, что в устройстве стенка баллона напротив самозат гивающегос  отверсти  выполнена утолщенной и внутри утолщени  расположен металлический элемент, На чертеже изображено окклюзирующее устройство в сечении. Устройство содержит катетер 1 с уменьшенным по диаметру участком 2 и сферической головкой 3 на рабочем конце, а также эластичный баллон 4 с самозат гивакщимс  отверстием, через которое проведен участок 2 катетера. Стенка баллона 4 напротив самозат гиваквдегос  отверсти  имеет утолщение 5, внутри которого размене- металлический элемент 6.The invention relates to medicine, namely to vascular surgery and neurosurgery, and is intended primarily for the occlusion of the lumen of the pathological vessels of the brain. An occlusive device is known which consists of an elastic balloon with a hole in the proximal end and a catheter temporarily inserted into this hole. The working part of the catheter (connecting to the balloon) is made with a reduced diameter section and an extended spherical head, thanks to which the balloon is installed in a predetermined part of the vessel and the balloon is prevented from falling off the catheter by the il blood stream. However, this device is difficult to conduct through convoluted and branched blood vessels, since when a balloon is introduced into a blood vessel, the laminar blood flow is replaced with a blunt flow. The balloon attached to the refined working end of the catheter begins to vibrate relative to the longitudinal axis of the vessel. The balloon becomes uncontrollable, it cannot be inserted into a pathological vessel twisted from a lion vessel. In this case, the balloon can become across the vessel, looping the curved refined part of the catheter, which not only makes it impossible to further advance the balloon through the vessel; but it also makes it difficult to remove it from the vessel. The purpose of the invention is to provide the ability to hold the balloon through the winding and branched blood vessels. This goal is achieved by the fact that in the device the balloon wall opposite the self-expanding hole is made thickened and the metal element is located inside the bulge. The drawing shows an occlusive device in cross section. The device contains a catheter 1 with a reduced diameter section 2 and a spherical head 3 at the working end, as well as an elastic balloon 4 with a self-engaging opening through which the catheter section 2 is passed. The wall of the cylinder 4 opposite the hole of the air vent has a thickening 5, inside of which there is a metal element 6.
