超音波プローブアダプタに接続された外部磁気源とをさらに含む請求項1に記載の装置。 - 第1磁石は、バルーンの第1側に位置決めされ、
第2磁石は、バルーンの第2側に位置決めされ、
第1磁石および第2磁石は、外部磁気源との磁気吸引を発生するように構成され、
外部磁気源は、第3磁石および第4磁石を含む、請求項4に記載の装置。 - 第1磁石および第2磁石は、第3磁石および第4磁石が互いに離れた距離と等しい距離だけ、互いに離れている請求項7に記載の装置。
- 前記磁石および前記外部磁気源は、チューブの遠位端を外部磁気源に向けて引き寄せるように配向した磁場を有する請求項3に記載の装置。
- 管腔内に配置され、そこを通って延びているスネアラインであって、チューブの近位端より近位側に配置された近位端、およびバルーン内に配置された遠位端を有するスネアラインと、
スネアラインの遠位端に接続され、バルーン内に配置されるスネアであって、バルーン内部に受け入れられたガイドワイヤの遠位端と係合して保持するように構成され、ガイドワイヤの近位端は、チューブの近位端を患者の食道を介して患者から引き出すことによって、患者から引き出し可能である、スネアと、をさらに備える請求項1に記載の装置。
