Abstract
【解決手段】カテーテルが、灌注式の焼灼用の先端部電極内で遠位側の同軸の位置に位置センサーを支持する。先端部電極は、空洞を画定するシェル壁を有し、その空洞を通じて、流体が流れ、シェル壁に形成された流体ポートを経由して脱出する。その空洞は、内部部材によって密封され、内部部材は、阻流部分と遠位部分によって空洞の中に延びる。遠位部分は位置センサーを安全に収容し、阻流部分は、空洞を通じた流れをより一様にするために、先端部電極に進入する流体を拡散し、分散する。先端部電極上のすべての箇所で冷却をより一様にするために、遠位部分は、先端部電極の長さ方向に沿って延びる環状領域を設けて、先端部電極上のより遠位側の流体ポートへの流体供給を改善するように構成されている。
