摘要：
The present invention provides a guidewire which is excellent in steerability such that the guidewire is capable of efficiently reaching a target spot, and enables tunneling surgical procedure by increasing stiffness of the guidewire during treatment of lesions. More specifically, the present invention provides a guidewire system which enables a magnetic field applied from the outside to perform a steering operation, and is capable of maintaining stiffness of the guide wire at the target spot. Further, the present invention provides a system which performs monitoring in real time during surgical procedure using a guidewire, and is capable of easily entering the guidewire to a surgical procedure region without damaging the blood vessel walls. In a tunneling guidewire, a guidewire (10) according to the present invention includes: a guidewire body (101) in which a hollow slot is formed a stopper part (103) which is housed in the slot such that the stopper part is movable forward and backward a wire (105) which includes members with different flexibilities and is connected to an end portion of the stopper part. A guidewire according to the present invention has a merit that it is capable of adjusting ductility for steering and stiffness for tunneling of the guidewire by leading in or drawing out a distal part (1051) of the wire having relatively high flexibility from the body of the guidewire according to movements of the stopper part in the slot.COPYRIGHT KIPO 2016본 발명은 터널링용 가이드와이어에 있어서, 내부에 중공형 슬롯이 형성된 가이드와이어 몸체 슬롯에 전후로 이동 가능하도록 수납된 멈치부 및 유연성이 서로 다른 부재를 구비하고, 멈치부의 단부에 연결된 와이어를 포함한다. 본 발명에 따르면, 와이어의 상대적으로 유연성이 높은 원위부가 멈치부의 슬롯 이동에 따라 가이드와이어 몸체로부터 인입 또는 인출되어 가이드와이어의 조향을 위한 연성과 터널링을 위한 강성을 조절할 수 있는 이점이 있다
