SYSTEM AND METHOD FOR CONTROLLING CATHETER POWER BASED ON CONTACT FORCE

摘要

A method for controlling an ablation power applied to a catheter includes: receiving, by a controller, a detected contact force from a sensor assembly of the catheter, the sensor assembly being configured to detect a contact force applied to the electrode; controlling, by the controller, a power supplied to an electrode of the catheter to have a deactivated power level when the detected contact force is less than a first threshold contact force; controlling, by the controller, 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 controlling, by the controller, 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.

主权项

1. 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; andcontrol 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.
