Summary:PROBLEM TO BE SOLVED: To provide systems and methods for providing and using an irrigated ablation catheter.SOLUTION: The catheter may include a distal shell electrode having irrigation apertures. An insert disposed within the electrode has protrusions that mate with orifices in the shell of the electrode. Each protrusion has a port communicating with at least one interior lumen in the insert, and a sensor is disposed in each port. A support seals the proximal end of the electrode and engages the insert. The plurality of sensors may be used to measure electrical and thermal characteristics surrounding the electrode, and may help assess contact between the electrode and tissue and/or determine movement of the electrode during ablation.SELECTED DRAWING: Figure 1 【課題】 灌注アブレーションカテーテルを提供及び使用するためのシステム及び方法を提供する。【解決手段】 このカテーテルは、灌注開口部を有する遠位側外殻電極を含み得る。電極内に配置されたインサートは、電極の外殻内のオリフィスと嵌合する突起を有する。各突起は、インサート内の少なくとも１つの内部管腔と連通するポートを有し、センサが各ポート内に配置される。支持体が、電極の近位端を密封し、かつインサートに係合する。複数のセンサを使用して、電極周囲の電気的及び温度特性を測定することができ、これは、電極と組織との接触を評価し、及び／又は、アブレーション中の電極の動きを判定するのに役立ち得る。【選択図】 図１
