Abstract
【解決手段】付勢された、面内の双方向の偏向を有する、改善された操作可能なカテーテルは、細長いカテーテル本体と、偏向の平面を画定する牽引ワイヤのための軸外で対向する少なくとも第1及び第2のルーメンを含む管を有する偏向可能な中間区域と、カテーテル本体の近位端に位置する制御ハンドルとを有する。この偏向可能な中間区域は、長手方向に沿って延び、偏向の平面に対して垂直な平面上にある、少なくとも2つの細長い付勢部材を含むことにより、偏向の平面外における屈曲に抵抗する。より詳細な実施形態では、偏向可能な中間区域は、内側層と、内側層を囲繞する編組みメッシュと、外側層とを含む統合された管状構成体を有し、付勢部材は、内側層と編組みメッシュとの間、又は編組みメッシュと外側層との間に配置され得る。
