Abstract
Systems and methods for controlling energy delivered for thermal ablation. An apparatus may include a conductive member comprising an array of conductive filaments, a power supply configured to provide the current to the conductive/resistive member in a plurality of electrical pulses, and a processing circuit coupled to the power supply. The processing circuit is configured to control the supply current value to be greater than or equal to a first current density and less than or equal to a second current density, and control the pulse length to be greater than or equal to a first pulse length and less than a second pulse length, control the supply current value to have a third current density at a first time and a fourth current density at a second time.
