Aneurysm blocking cover

Abstract

The invention discloses an aneurysm blocking cover, which comprises a conveying guide wire; the aneurysm blocking cover is characterized by being provided with a blocking bracket body; a marking point is arranged between the conveying guide wire and the blocking bracket body; the blocking bracket body is of a net structure which is knitted by a nickel-titanium alloy wire or a platinum alloy wire and has contractility; the center of one end of the blocking bracket body is sealed and connected with the conveying guide wire, the other end is open and the blocking bracket body is gradually expanded towards the open end through the sealed end and extends to form a cover, so that an aneurysm wall is blocked through the cover-shaped blocking bracket body when an aneurysm is blocked, and the inner wall of a blood vessel proliferates to form thrombus to be quickly closed. Therefore, the aneurysm blocking cover has the advantages of being novel in structure, significant in blocking effect, few in complications and short in recovery time.

Description

technical field [0001] The invention relates to a medical device, in particular to an aneurysm blocking cover. Background technique [0002] Aneurysm is a continuous expansion disease caused by local weakness of arterial wall. Cerebral aneurysm belongs to peripheral aneurysm, which refers to tumor-like protrusions produced by the limited expansion of cerebral aneurysm wall. The protruding aneurysm wall is in the Under the continuous impact of blood flow, it gradually thins and eventually ruptures and bleeds. Cerebral aneurysm rupture and hemorrhage have acute onset, severe symptoms, no obvious aura, and high mortality and disability rates. The treatment of cerebral aneurysms is mainly divided into surgical clipping and endovascular interventional embolization. However, surgical clipping has large trauma, many complications, long operation and recovery time, and is not welcomed by doctors and patients. With the development and progress of minimally invasive endovascular in...

Problems solved by technology

[0003] At present, some of the existing aneurysm occluders use spherical irregular filling coils. The substantive disadvantage of this structure is that the coils do not occupy enough space, will not compress the aneurysm wall, and the filling effect is not good; Cylindrical stent, the substantive disadvantage of this structure when filling aneurysms is that the density of stents is small, and the inner wall of the aneurysm will not proliferate and form a thrombus to close, so the filling effect is not good
