Description
本発明は更に、体腔に挿入される可撓性を備えたカテーテルに関し、前記カテーテルの先端に設けられた先端側孔から、該カテーテルの基端から先端方向へ離間する位置に設けられた基端側孔へ延びる、ガイドワイヤを収容するためのガイドワイヤルーメンと、前記ガイドワイヤルーメンから隔離された剛性部材ルーメンと、前記剛性部材ルーメンはカテーテルの基端からカテーテルの先端の開口へ延びて、該剛性部材ルーメンに供給された流体がカテーテルの先端に隣接する体腔領域へ送達されることと、前記剛性部材ルーメン内にてカテーテルの基端から前記基端側孔の隣接位置へ延びる剛性を備えた剛性部材とを有し、前記剛性部材は、前記剛性部材ルーメンから取り外し可能であることとを特徴とする。
。即ち、ガイドワイヤ14の殆どはカテーテル10の外部に存在して接触可能であるため、操作者はガイドワイヤ14の体腔の挿入地点付近においてガイドワイヤ14を把持して、カテーテル10が後退される際のガイドワイヤ14の定位置からの移動を、手動により阻止し得る。基端側孔20が身体から退出する際、操作者は、先端側孔18が身体から退出する迄、ガイドワイヤ14のより基端側部分を把持し得る。この時点で、操作者は、先端側孔18から身体内へ延びているガイドワイヤ14部分を把持しながら、カテーテル10をガイドワイヤ14から完全に除去することが可能である。その後、ガイドワイヤ14基端が標準的方法によって第二カテーテル内に挿入されて、第二カテーテルがガイドワイヤ14に沿って目標領域へと前進され得る。このように、操作者は全操作工程の間、ガイドワイヤ14の把持を維持して、ガイドワイヤ14の目標領域における位置を維持し得る。
と置換されるべき場合、操作者は単に片手でガイドワイヤ14の露出部分を保持してガイドワイヤを定位置にて維持し、先端側孔18が身体から退出するまで他方の手でカテーテル10を引き抜く。この時点で、操作者は、先端側孔18から先端方向に延びるガイドワイヤ14部分を把持して、ガイドワイヤ14からカテーテル10を完全に除去する。その後、任意の所望のカテーテルをガイドワイヤ14に連結して目標領域へと前進させ得る。カテーテルの交換は、例えば第一バルーンの留置に失敗した場合、あるいは目標部位の近接位置からの検査によって腔の治療に異なる外科器具を要することが判明した場合等に必要となり得る。
