Catheter with Flow Diverter and Force Sensor

A catheter probe, comprising:

• an insertion tube defining a longitudinal axis;
• a distal electrode;
• a proximal electrode;
• a joint sensing assembly disposed between the insertion tube and the distal electrode, the joint sensing assembly including a transmitting coil and a plurality of receiving coils spaced apart along the longitudinal axis of the insertion tube,
• a coupling member having a first portion coupled to the transmitting coil and a second portion coupled to the plurality of receiving coils, the second portion of the coupling member having a proximal portion with a central space and a proximal opening with a slot,
• a diverter positioned in the slot, the diverter having a proximal entry opening and a distal exit opening, the diverter having a fluid passage with a radial branch and an axial branch;
• and
• a first tubing extending from a proximal end of the insertion tube to the proximal entry opening of the diverter, the first tubing configured to supply irrigation fluid to the fluid passage, and the proximal electrode is mounted on the proximal portion of the joint sensing assembly and is positioned over the distal exit opening.
