<P>PROBLEM TO BE SOLVED: To provide a catheter for an endoscope which can surely and easily be operated while having a simple constitution, and at the same time, can be provided at a low cost. <P>SOLUTION: This catheter for the endoscope is equipped with an external sheath 1, and a distal end working section 102. In this case, the distal end working section 102 is arranged between the distal end sections of an internal sheath 2 which is freely movably assembled relative to the external sheath 1, and which enables the operations to expand and contract the diameter thereof by the movement of the sheaths. <P>COPYRIGHT: (C)2007,JPO&INPIT |
