摘要

There is disclosed a guiding tube (11) for introducing rod-like medical instruments such as a catheter (15), which can be easily split and removed from, for example, a catheter (15), after the catheter (15) inserted through the guiding tube (11) has been attached to a blood vessel. The guiding tube (11) comprises a main body (13) provided with a longitudinal slit (12) and formed of a mixture of first and second materials and a stripe (14) detachably embedded liquid-tight in the slit (12) of the main body (13) and formed of a third material which exhibits a good bonding to the second material, but a poor bonding to the first material.
