SOLUTION: The catheter tip 300 is provided with four ribs 340 projecting outward at the outer periphery of a catheter tip main body 300' having a channel 310 along a longitudinal direction inside. The respective ribs 340 are installed at the interval of nearly 90 deg. (regular intervals) in the peripheral direction of the main body 300'. The respective ribs 340 are extended by a length L2 along the longitudinal direction (axial direction) of the main body 300' (linearly) except for the tip part 301' of the main body 300'. The heights of the respective ribs 340 are gradually increased toward a base end from the tip. The inner diameter of the channel 310 is desirably 0.3 to 5.5 mm. |
