A mapping and ablation catheter with contact force sensing capabilities at a distal end, includes a catheter body, a deflectable section, and a distal tip section which has a tip electrode and a contact force sensor for sensing a contact force vector applied to the tip electrode.
The contact force sensor is arranged between the deflectable section and the tip electrode and has a CUP shaped body, a plurality of spokes, a beam member, and at least one strain gage mounted on one of the spokes. The spokes are arranged to converge at a location on the body from which the beam member extends, wherein an end of the beam member is connected to the tip electrode. |
