Abstract

The invention discloses a multi-point electrolytic detachment system and method for detaching embolism materials. The system comprises a spring ring and a spring ring conveying system. The spring ring comprises a plurality of end-to-end small spring rings and detachment points for connecting the small spring rings. The spring ring conveying system comprises a conveying guide wire and a micro catheter. The conveying guide wire is arranged inside the micro catheter. The front end of the conveying guide wire is connected with the tail end of the spring ring through the last detachment point, an electrified wire is arranged at the front end of the micro catheter, a micro wire is arranged on the wall of the micro catheter, and the micro wire is connected with the electrified wire. Different detachment points are arranged on the spring ring, detachment is performed at nearby detachment points after arterial aneurysm embolism is satisfied, an existing multi-spring-ring implanting method is replaced, the operation time is shortened, and the operation cost of a patient is lowered.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a multi-point electrolysis system and release method for releasing embolic materials, which is a multi-point electrolysis system for releasing embolic materials during the embolization process of intracranial aneurysm interventional treatment The principle of the system is to deliver the coiled embolization material into the aneurysm through the matching microcatheter, and set different release points on the coil according to the length. When the aneurysm is satisfied during the operation, it will be released at the nearest release point. Background technique

[0002] A large number of autopsy or angiographic studies show that the incidence of intracranial aneurysms in the entire population is as high as 2%-4%. Once the intracranial aneurysm ruptures and bleeds, its mortality rate and disability rate are high. If two hemorrhages occur, the mortality rate is as high as 60%...
