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 【解決手段】 狭窄病変部位を熱変成させて拡張させる医療装置１は、先端にバルーン３ａの設けられたバルーンカテーテル３と、レーザ光を発振するレーザ発振器５と、上記バルーンカテーテル３の内部に配設されて上記バルーン３ａまでレーザ光を導光するカテーテルファイバー６とを備えている。上記カテーテルファイバー６の入射部６ａを保持する保持部材４１と、当該保持部材４１を移動させる移動手段４２と、上記カテーテルファイバー６の入射面を清掃する清掃手段４３とからなる接続手段７を設け、清掃手段４３がカテーテルファイバー６の入射面を清掃すると、上記移動手段４２が上記入射部６ａをコネクタ８まで移動させてこれらを接続させるようになっている。【効果】 カテーテルファイバーの入射部をコネクタに接続する際に生じる、入射面の損傷や汚れの付着を防ぐことができる。【選択図】 図３
