摘要

(57) Abstract Possessing the common distal (2036) lumen, the independent specialist exchange type gallbladder road catheter which becomes. Including the long shaft where the gallbladder road catheter becomes, demarcating the auxiliary lumen, demarcating of proximal part and the common lumen of guide wire lumen and auxiliary lumen which become possessing with the distal (2036) part which becomes, it becomes. The contour of the shaft distal (2036) part is reduced by the common distal (2036) lumen. The long shaft becomes in order to make the use by the independent specialist easy, also the proximal guide wire port which is arranged with the proximal edge of the said shaft and the distal (2036) edge of the said shaft including. The seal adjoining to the proximal guide wire port, the port is sealed up by being arranged. The shaft including with the single lumen distal (2036) part and the bi- lumen proximal part, it becomes desirable. The single lumen distal (2036) part of the shaft is curve possible, also it is possible to include the tapering or spherical distal (2036) point and to become.
