Abstract

A catheter system for use with a catheter with a distal assembly supporting a plurality of electrodes adapted to sense electrical signal in heart tissue and a force sensor configured to generate first contact signals representative of a contact force acting on the distal assembly. The system includes an ablation power generator configured to energize the plurality of electrodes, an impedance circuitry configured to generate second contact signals representative of the electrodes in contact with tissue, a processor configured to receive the first and second contact signals and generate switch signals in response thereto, and a switch circuitry configured to connect in response to the switch signals solely selected electrodes in contact with tissue to the ablation power generator in forming one or more composite electrodes.
