Abstract

The invention discloses an intracranial dense mesh stent with an anticoagulant coating. The intracranial dense mesh stent comprises a dense mesh stent body and a hydrophilic polymer material covering the dense mesh stent body, wherein the dense mesh stent body is coated with the anticoagulant coating. According to the intracranial dense net stent, not only can a channel be reconstructed for blood vessels, but also antithrombotic treatment can be carried out on the blood vessel wall at the position of stent implantation, and embolism treatment can be carried out on aneurysm at the same time.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, in particular to an intracranial dense mesh bracket. Background technique

[0002] Intracranial aneurysm refers to a tumor-like protrusion produced by the limited expansion of the cerebral artery wall. The protruding aneurysm wall gradually becomes thinner under the continuous impact of blood flow 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 interventional therapy technology, more and more patients with cerebral aneurysm receive endov...
