Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a balloon suction catheter device for intracranial thrombus removal. Background technique

[0002] Stroke is one of the common diseases in the world, and its characteristics are: high incidence rate, high prevalence rate, and high disability rate. The annual incidence of cerebrovascular disease in my country's urban areas is 219 / 100,000, and that in rural areas is 185 / 100,000, and it is still increasing year by year. From 1998 to 2008, the prevalence of cerebrovascular disease increased from 5.9‰ to 9.7‰. Among the surviving patients with cerebrovascular disease, about three-quarters are disabled to varying degrees. It is reported that 80% of stroke patients have different degrees of limb dysfunction, and 43.7% of them cannot take care of themselves.

[0003] Intravenous rt-PA thrombolysis is currently the only effective treatment for acute cerebral infarction proven by evidence...
