<P>PROBLEM TO BE SOLVED: To provide a medical instrument having a groove of such depth as not to reach a lumen in order to thin the distal end of a catheter, and having excellent operability by improving the flexibility without increasing the sliding resistance even if the instrument hits against an inner wall surface of a body cavity, etc. <P>SOLUTION: The catheter 10 is a long-length medical instrument to be inserted into the body cavity. A recess groove 65 extending in the axial direction of the catheter 10 is disposed on the outer peripheral surface. An end face 65a on the distal end side of the recess groove 65 is carved on the outer peripheral surface of the catheter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
