The invention relates to a catheter with a flow diverter and a force sensor. A catheter probe comprises an insertion tube, and a distal end with a distal electrode, a force sensor to detect force on the distal electrode, and an irrigated electrode mounted on a coupling member of the force sensor, which has a tubular form surrounding a central space occupied by components, including force sensing coils. A fluid diverter that passes fluid to the proximal irrigated electrode is configured as an insert or an integrated projection of the coupling member, which configuration minimizes its space demand within the coupling member. Thus, the diameter of the distal end need not be increased. The fluid diverter has a proximal entry opening and a distal exit opening connected by a fluid passage with at least a radial branch and at least an axial branch. The irrigated electrode is mounted over the distal exit opening to receive fluid from the fluid passage. 本发明题为"具有分流器和力传感器的导管"。本发明提供了种导管探头，其包括插入管，和具有远侧电极的远侧端部，用于检测远侧电极上的力的
