Abstract
Description
本発明は、管腔内に挿入されるガイド部材と、該ガイド部材の先端側に設けられ、前記ガイド部材の基端側まで延びる第1の流路が接続された第1のバルーンと、前記ガイド部材に、前記第1のバルーンから基端側に離れた位置に設けられ、前記ガイド部材の基端側まで延びる第2の流路が接続された第2のバルーンと、前記ガイド部材に沿って前記第1のバルーンと第2のバルーンとの間の位置から基端側まで延び、基端側に流体を供給または排出するポートを有する第3のバルーンと、前記第1のバルーンと前記第2のバルーンとの間に吐出口を有し、前記ガイド部材の基端側まで延びる洗浄用流路とを備える医療用デバイスを提供する。
このようにすることで、第2のバルーンを、第1のバルーンに近い位置から基端側に向かって移動させながら、第3のバルーンを膨張させることにより、第3のバルーンを先端側から均一に膨張させることができる。
このようにすることで、患部の処置の後、ガイド部材および第1のバルーンを残したまま第3のバルーンを管腔内から取り除くことにより、腔壁に空いた穿孔の処置を容易にすることができる。
このようにすることで、患部の処置の後、第2のバルーンを体外に移動させ、該第2のバルーンに被覆部材を装着して再び管腔内に挿入し、腔壁に穿孔が形成された位置において第2のバルーンを膨張させる。これにより、管腔内で半径方向に拡張した被覆部材により穿孔を被覆することができる。
この場合、前記被覆部材が、生分解性の材料からなることとしてもよい。このようにすることで、手術後に被覆部材を管腔内から取り除くために処置を不要にすることができる。
本実施形態に係る医療用デバイス1は、図1に示されるように、管腔内に挿入可能な細長いガイド部材2と、ガイド部材2の側面に設けられた第1および第3のバルーン31,33と、ガイド部材2が長手方向に移動可能に挿入されたシース4と、該シース4の先端部に設けられた第2のバルーン32とを備えている。
第1のバルーン31は、ガイド部材2の先端部に設けられている。第3のバルーン33は、第1のバルーン31の基端側に隣接した位置からガイド部材2の基端側まで延びる細長い形状を有している。第1および第3のバルーン31,33は、ガイド部材2を全周にわたって覆い、ガイド部材2を略中心軸にして膨張する。ここで、第1および第3のバルーン31,33は、適用される管腔の内径よりも十分大きな外径まで膨張可能である。第3のバルーン33は、例えば、基端側に向かって比較的大きな力で引っ張ることにより、ガイド部材2から取り外すことができるようになっている。
