Intracranial aneurysm is a local abnormal bulge of the intracranial artery lumen, which mostly occurs in the arterial ring and its main branches at the base of the brain. Direct surgery is the main me

There is no strict definition of microcatheter. Catheters with an outer diameter less than 3 French size are usually called microcatheters. French size is simply F, or Fr, 3Fr=1mm, that is, 1F≈0.33mm.

Ethylene vinyl alcohol (EVOH) (Lava) is a copolymer with a dimethyl sulfoxide (DMSO) solvent and a suspension of (radiopaque) micronized tantalum powder. When injected through a catheter and mixed wit

At present, a large number of international clinical studies have confirmed that stent thrombectomy can benefit patients with acute ischemic stroke. In recent years, aspiration thrombectomy techniques

Stroke, also known as brain stroke, is caused by sudden rupture and bleeding of blood vessels in the brain or cerebral ischemia and lack of oxygen due to blood vessel blockage. Clinically, it is divid

Detachable Aneurysm Coiling System is a type of treatment used for brain aneurysms, which are bulges or weak spots in the walls of blood vessels in the brain. The treatment involves placing a small, f

Introduction to Blood Clot Types Before introducing the thrombus aspiration catheter, let us first introduce the target of the thrombus aspiration catheter - thrombus. Thrombus can be roughly classifi

Guiding Catheter The guiding catheter is used to provide support for the distal access. The ideal guiding catheter should not recoil into the aorta when advanced and needs to provide a stable support

Aspiration Catheter In the field of acute ischemic stroke (AIS), mechanical thrombectomy is divided into two major directions. One is thrombectomy through stent, which requires the use of thrombectomy

LAVA Liquid Embolization System (LES) is a minimally invasive technique used for the treatment of arteriovenous malformations (AVMs) in the brain. AVM is an abnormal connection between arteries and ve

Arteriovenous malformations (AVMs) are abnormal tangles of blood vessels that disrupt normal blood flow. These malformations can lead to a range of neurological symptoms, such as headaches, seizures,

Analysis of Key Performance The key performance indicators of the thrombus aspiration catheter mainly include the following points: 1. Position performance; 2. passability; 3. lumen negative pressure
