The present invention provides a pathway to disease lesions in organs or blood vessels become narrow relates to a catheter structure for reinforcing strength of the stent can not be discharged to the outside of the body in at least the free length of the guide wire, and the bending phenomenon occurs when the treatment tube to guide the stent to a lesion site to extend the More particularly, is coupled to the grip body and the guide tube and the outer tube portion made of a discharge hole is formed is discharged outside the wire, through the outer tube holding portion connected to the plunger body is inserted into the front of the outer tube and the guide and moving the tube section consisting of a discharge hole formed tube discharged the wire moves, the moving parts of the tube movement, the tube front end attached to the front end of the rear end portion is inserted in a state inserted into the stent is mounted by reducing the volume of the inner part the outer tube and a stent made of a tube portion, the outer tube, so that the outlet hole of the moving around the tube during the bending procedure the developer discharge hole is not generated, each comprising a reinforcing member is fitted is adhered and fixed so as to be exposed characterized in that it is composed It is effective to minimize the length of the treatment was to increase the convenience of the patient so as not interfere with the activity of the blood vessels of the body organ or a lesion to stenting or other procedures within the body so as to insert a guide wire guided procedures.본 발명은 질환으로 통로가협소해진 혈관이나 신체기관의 병변부위를 확장시키기 위한 스텐트를 병변부위로 안내하는 가이드와이어를 최소의 여유 길이로 인체 외부로 배출시킬 수 있으며 시술시 튜브에 꺾임현상이 발생되지 않도록 강도가 보강된 스텐트 시술용 카데터 구조에 관한 것으로, 더욱 상세하게는 파지몸체에 연결되며 가이드와이어가 배출되는 배출홀이 형성된 외부튜브로 이루어진 외부튜브부와, 상기 외부튜브부의 파지몸체를 관통하여 외부튜브의 내부로 삽입되는 밀대 전방으로 연결되며 가이드와이어가 배출되는 배출홀이 형성된 이동튜브로 이루어진 이동튜브부와, 상기 이동튜브부의 이동튜브 선단에는 내부에 스텐트가 부피를 축소하여 삽입 장착된 상태로 후단부가 외부튜브의 전방 끝단에 일부 삽입되는 장착튜브로 이루어진 스텐트부와, 상기 외부튜브, 이동튜브의 배출홀 주변이 시술
