Description
第1の端部と第2の端部とを備える胆管挿入用チューブであって、
前記第1の端部を有し、胆管内に挿入可能な径により形成される第1の部分と、
前記第2の端部を有し、腸管内に配置可能な径により形成される第2の部分と、
前記第1の部分に配置された第1の膨張部材と、を備え、
前記第1の膨張部材は、該第1の膨張部材が内部に有する空隙に気体又は液体を注入されることにより、前記胆管挿入用チューブの径方向に膨張する
ことを特徴とする。
以下で、本発明の一実施例に係るチューブ100について、詳しく説明する。チューブ100は胆管挿入用チューブである。チューブ100は後に説明するように、胆汁を消化管内へと運ぶために胆管に挿入される。
図3は、本実施例に係るチューブ100の外観図を示す。図4Aは、本実施例に係るチューブ100の、チューブ100に対して平行な方向の断面図を示す。図3に示すように本実施例に係るチューブ100は、チューブ本体130と、少なくとも1つの膨張部材(バルーン150)とを備える。以下に本実施例に係るチューブ100が備える各部の寸法の例を示すが、本実施例に係るチューブ100が以下に示されるものに限定されるわけではない。例えば、以下に示す寸法のチューブ100は成人男性に対して好適に使われうるが、例えば小児に対して用いる場合はより小さい寸法のチューブが用いられうる。
本実施例に係るチューブ100は、胆汁の動態を調節するために用いられうる。具体的には、本実施例に係るチューブ100は、その一端115が胆管内に配置され、他端125は十二指腸と胆管との交点よりも肛門に近い消化管内に配置される。こうして胆汁は、胆管内に配置された一端115から、他端125へと運搬される。
