Intracranial aneurysm interventional embolization treatment device

Abstract

The invention discloses an intracranial aneurysm interventional embolization treatment device. The device comprises a plugging device and a conveying device. The plugging device is a net-shaped plugging object which is formed by knitting metal wires with a memory effect or high-elasticity polymer wires and developing wires. The plugging device comprises an upper part and a lower part which refer to an upper end intra-tumor part and a lower end extra-tumor part respectively. The upper end intra-tumor part and the lower end extra-tumor part are connected together to form a coating space for coating an aneurysmal neck. The conveying device comprises a conveying guide pipe and a conveying guide wire. In the conveying process, the plugging device is lengthened to be placed in the conveying guide pipe, and the conveying guide wire is connected with the tail of the plugging device. According to the intracranial aneurysm interventional embolization treatment device, intra-tumor thrombi can be induced to be formed, blood vessel repair of the aneurysmal neck is promoted, and therefore the purpose of healing arterial aneurysm is achieved. Moreover, parent blood vessels and normal branches cannot be affected obviously.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracranial aneurysm interventional embolization treatment device. Background technique [0002] A large number of autopsy or angiographic studies show that the incidence of intracranial aneurysms in the entire population is as high as 2%-4%. Once the intracranial aneurysm ruptures and bleeds, its mortality rate and disability rate are relatively high. If two hemorrhages occur, the mortality rate is as high as 60%-80%. This disease seriously threatens human life and health. Therefore, exploring a safer and more effective method of treating intracranial aneurysms has also become a key research content in this field. [0003] In 1991, Guglielmi et al reported for the first time electrolytic coil embolization in the treatment of intracranial aneurysms. The interventional treatment of intracranial aneurysms has gone through the concept of simple coil embolization in the...
