A catheter includes a proximal shaft having a relatively high rigidity, a distal shaft provided on a front portion of the proximal shaft so as to be in fluid communication with proximal shaft and having a rigidity lower than that of the proximal shaft, a hub mounted to the vicinity of a rear end of the proximal shaft and configured to allow a pressure applying apparatus to be mounted to the hub, and a balloon provided on a front portion of the distal shaft so as to be in fluid communication with the distal shaft and configured to receive pressure applied from the hub. The catheter also includes a guide wire lumen. In this catheter, at least a front portion of the distal shaft is configured as a grooved portion having a groove or grooves.

Catheter and medical tube

A tubular medical device comprises a tubular body, a lumen, a compression-resisting member inserted in the lumen so that it cannot move in the direction of the axis of the tubular body, with its distal end located at a predetermined distance from the distal end of the tubular body toward the proximal end, a pull wire whose distal end is secured near the distal end of the tubular body at a position deviated from the axis of the tubular body and which is led in the tubular body to the proximal end of the tubular body, and a pulling mechanism for pulling the pull wire toward the proximal end of the tubular body which is attached to the proximal end of the tubular body and has a manipulation dial. The compression-resisting member consists of a main body and a secured portion. The compression-resisting member main body, and has a property of resisting compression in the axial direction of the tubular body. The secured portion retains the main part in place in the lumen.
