Abstract:
The present invention relates to a medical instrument with which sliding properties of an intra-lumen operation wire can be improved. This medical instrument (for example a catheter (10)) is provided with: a long flexible medical-instrument main body (a sheath (16)) which is inserted into a body cavity; a lumen (for example a sub-lumen (30)) which is formed inside the medical-instrument main body along the length direction of the medical-instrument main body; and an operation wire (40). The operation wire (40) is accommodated inside the lumen, extends along the length direction of the lumen, and is capable of being slid in the length direction of the lumen. Pulling operations of the operation wire (40) can be used to bend the medical-instrument main body. A lubricant (45) is adhered to at least a surface of the operation wire (40).
