Claims (1)
- ガイドワイヤと共に使用されるカテーテルであって、
近位部分、遠位部分、及びこれらの間に位置し、変形可能な断面を有する変形可能なセクションであって、前記変形可能なセクションの断面が、第1の側の弾性材料及び第2の側の可撓性支持材料を含み、膨張管腔が、前記弾性材料及び前記可撓性支持材料の両方によって囲まれ、前記変形可能なセクションの断面が、前記変形可能なセクションの長さに沿って回転し、これにより、前記弾性材料、前記膨張管腔、及び前記可撓性支持材料が、前記変形可能なセクションの前記長さに沿って螺旋状に延在する、セクション、
少なくとも前記変形可能なセクションの前記長さに沿って、少なくとも前記カテーテルの近位部分まで前記可撓性支持材料を通るプルワイヤであって、前記プルワイヤに近位側への張力がかかると、前記変形可能なセクションが螺旋形状に変形する、プルワイヤ、
前記遠位部分を通るガイドワイヤ管腔であって、前記ガイドワイヤ管腔を閉塞させるために前記ガイドワイヤ管腔内に配置された作動可能な構造を有し、これにより、前記ガイドワイヤが、前記ガイドワイヤ管腔内に配置されている場合は、前記作動可能な構造の作動が、前記ガイドワイヤ管腔を閉塞させて前記ガイドワイヤに対して圧迫力を加える、ガイドワイヤ管腔、を備え、
前記膨張管腔内の圧力が上昇すると、前記弾性材料が、前記可撓性支持材料から離れる方向に拡張する、カテーテル。
