< Topic >Balloon Drive is possible accurately under appropriate conditions, at the time of clinical research and trouble correspondence the balloon catheter and the Drive system whose it is possible to analyze the Drive state of the balloon catheter easily, are offered.SolutionsThe balloon section being concatenated by the rear end of 22 expanding and contracting and balloon section 22, the catheter tube it is concatenated the pressure fluid by the rear end of 24 where the fluid pressure continuity path which it introduces and guides and was formed and catheter tube 24 inside balloon section 22, the handle section 42 which has the 1st aisle where the pressure fluid introduction exit which is communicated with inside the fluid pressure continuity path is formed at least and, IC tip/chip it possesses with 60 and Communication Div. 70. As for IC tip/chip 60, extended major diameter of balloon section 22 and the data regarding capacity and product number are stored, Communication Div. 70 reads out the data of IC tip/chip 60 and writes.< Choice figure >Figure 1A【課題】適切な条件で正確にバルーン駆動が可能であり、臨床研究やトラブル対応時にバルーンカテーテルの駆動状態を容易に解析することが可能なバルーンカテーテルおよび駆動システムを提供する。【解決手段】拡張および収縮するバルーン部22と、バルーン部22の後端に連結されて、バルーン部22内に圧力流体を導入および導出する流体圧導通路が形成されたカテーテル管24と、カテーテル管24の後端に連結され、流体圧導通路内と連通する圧力流体導入出口が形成される第1通路を少なくとも持つハンドル部42と、ICチップ60と、通信部70とを有する。ICチップ60は、バルーン部22の拡張外径および容量と製品番号に関するデータが記憶してあり、通信部70がICチップ60のデータの読み出しや書き込みを行う。【選択図】図1A
