Claim 13:
14. A power controller configured to be coupled to a catheter assembly, the catheter assembly including a first tissue contact surface, a second tissue contact surface, and a heating element coupled to the first tissue contact surface, the power controller comprising:
a housing;
a power supply within the housing; and
an electronic circuit system within the housing, the electronic circuit system including:
a startup module implemented in at least one of a memory or a processing device, the startup module configured to receive a calibration parameter associated with at least one of the catheter assembly or the heating element when the catheter assembly is electronically coupled to the power controller;
a feedback module implemented in at least one of the memory or the processing device, the feedback module configured to receive a temperature feedback signal of the first tissue contact surface and a gap feedback signal associated with a sensed distance between the first tissue contact surface and the second tissue contact surface; and
a control module implemented in at least one of the memory or the processing device, the control module configured to A) select a control setting associated with the calibration parameter, from a plurality of stored control settings, based on the calibration parameter, B) send a first signal to the heating element, the first signal associated with a first temperature set point, C) change the first signal based on the control setting and the temperature feedback signal, and D) send, in response to the gap feedback signal, a second signal to the heating element, the second signal associated with a second temperature set point, wherein the second signal is a removal pulse that is configured to be initiated when the gap feedback signal indicates that a fistula has been created, the removal pulse comprising a pulse application that is sent in response to a gap distance check if the gap distance is less than a predetermined amount.
