SOLUTION: A medical device 1 that expands a stenosis lesion part by thermal denaturation comprises: a balloon catheter 3 of which tip end is provided with a balloon 3a; a laser oscillator 5 that oscillates laser light; and a catheter fiber 6 that is arranged inside the balloon catheter 3 and guides the laser light to the balloon 3a. There is provided connection means 7 formed of a holding member 41 that holds an incident part 6a of the catheter fiber 6, moving means 42 that moves the holding member 41, and cleaning means 43 that cleans an incidence plane of the catheter fiber 6. When the cleaning means 43 cleans the incidence plane of the catheter fiber 6, the moving means 42 moves the incident part 6a to a connector 8 to connect them.EFFECT: To prevent damage on an incidence plane or adhesion of a dirt that occur when connecting an incident part of a catheter fiber with a connector.SELECTED DRAWING: Figure 3 |
