A catheterization system comprising: a catheter comprising an electrode and a sensor assembly configured to detect a contact force applied to the electrode; and a controller coupled to the catheter, the controller comprising a processor and memory storing instructions that, when executed by the processor, cause the processor to: receive a detected contact force from the sensor assembly of the catheter; control a power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is less than a first threshold contact force; control the power supplied to the electrode of the catheter to have a first power level when the detected contact force is greater than the first threshold contact force; and control the power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is greater than a cutoff contact force, the cutoff contact force being greater than the first threshold contact force, wherein the catheterization system is characterized in that the memory further stores instructions that, when executed by the processor, cause the processor to control the power supplied to the electrode of the catheter in accordance with a power control curve of power against force, wherein the power control curve exhibits hysteresis. a catheter comprising an electrode and a sensor assembly configured to detect a contact force applied to the electrode; and a controller coupled to the catheter, the controller comprising a processor and memory storing instructions that, when executed by the processor, cause the processor to: receive a detected contact force from the sensor assembly of the catheter; control a power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is less than a first threshold contact force; control the power supplied to the electrode of the catheter to have a first power level when the detected contact force is greater than the first threshold contact force; and control the power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is greater than a cutoff contact force, the cutoff contact force being greater than the first threshold contact force, receive a detected contact force from the sensor assembly of the catheter; control a power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is less than a first threshold contact force; control the power supplied to the electrode of the catheter to have a first power level when the detected contact force is greater than the first threshold contact force; and control the power supplied to the electrode of the catheter to have a deactivated power level when the detected contact force is greater than a cutoff contact force, the cutoff contact force being greater than the first threshold contact force, wherein the catheterization system is characterized in that the memory further stores instructions that, when executed by the processor, cause the processor to control the power supplied to the electrode of the catheter in accordance with a power control curve of power against force, wherein the power control curve exhibits hysteresis.
