摘要：
A catheter probe comprises an insertion tube, and a distal end with a distalelectrode, a forcesensor to detect force on the distal electrode, and an irrigated electrodemounted on a couplingmember of the force sensor, which has a tubular form surrounding a centralspace occupied bycomponents, including force sensing coils. A fluid diverter that passes fluidto the proximalirrigated electrode is configured as an insert or an integrated projection ofthe coupling member,which configuration minimizes its space demand within the coupling member.Thus, the diameterof the distal end need not be increased. The fluid diverter has a proximalentry opening and a distalexit opening connected by a fluid passage with at least a radial branch and atleast an axial branch.The irrigated electrode is mounted over the distal exit opening to receivefluid from the fluidpassage.
