Abstract

A catheter is disclosed comprising a catheter shaft including a proximal end and a distal end. A flexible framework can be connected to the distal end of the catheter shaft, wherein the flexible framework includes a plurality of heating electrodes and a temperature sensor. The plurality of heating electrodes can be configured to be heated to a first temperature, the first temperature being lower than which radio frequency ablation is performed. The plurality of heating electrodes can be configured to be heated to a second temperature, the second temperature being a temperature at which radio frequency ablation is performed.
