In recent years,endovascular intervention therapy has gained popularity due to its advantages of minimal trauma and quick recovery,and become an essential method for treating cerebrovascular diseases.As a crucial surgical instrument in interventional therapy,catheters often require precise control of their tips to navigate through tortuous positions.Traditional catheters have shortages of fixed tip shapes,limited proximal torque transmission,and difficulty of manipulation,increasing the risk of complications during interventional procedures and prolonging surgical exposure time.With the rapid development of materials science and engineering,steerable catheter systems have become the spotlight of interventional physicians,making precise"bend control"possible.This article systematically explained the classification of steerable catheter systems,focusing on their application in neurointerventional therapy,and provided an outlook on the future development of steerable catheters.
