Abstract

The invention discloses a micro-occluder for cerebral aneurysm, which comprises a main body of the occluder, a filling liquid, a delivery tube, and a push catheter. A limit block is connected, and the liquid outlet end of the check valve is provided with a blocking body, the blocking body is made of biogel material with elastic deformation properties, and the filling liquid passes through the push conduit and the check valve Enter the bluff body. The parts of the invention have less dependence on the process size, and are especially suitable for small cerebral aneurysms. The filling fluid enters the blocking body through the push catheter and the check valve, so that the biogel material with elastic deformation performance can be used during the filling of the filling fluid. Elastic deformation occurs under the action, so as to expand and expand, and play the role of blocking cerebral aneurysms. The material of the blocking fluid is biogel material, which has bioadhesiveness and can successfully adhere to cerebral aneurysms, thereby Increase the strength of brain aneurysms and reduce the risk of brain aneurysm rupture.

Description

technical field [0001] The invention belongs to the technical field of interventional medical devices, and in particular relates to a cerebral aneurysm micro-occluder. Background technique [0002] Aneurysm is a common vascular disease, which is the result of expansion or bulging of the arterial wall due to lesion or injury of the arterial wall. According to the location of the aneurysm, it can be divided into peripheral aneurysm, abdominal aortic aneurysm, Thoracic aortic aneurysm, visceral aneurysm, cerebral aneurysm, etc. [0003] Cerebral aneurysm refers to a tumor-like protrusion of the arterial wall caused by the localized abnormal expansion of the inner cavity of the cerebral artery. It is a cystic aneurysm caused by local congenital defects of the cerebral artery wall and increased intracavitary pressure. bulging. That is to say, cerebral aneurysm is not a tumor in the true sense, but a cerebrovascular disease, but the blood vessel wall is weak, and a bubble has bu...
