Abstract
An apparatus and method for stopping of ablation energy delivery to tissues during cardiac ablation procedures provides added safety. The apparatus uses control switch mechanism comprising relay switch and circuitry inserted between the ground patch and ablation generator. Alternatively, the control switching means can be on the catheter side of the ablation circuit. The switching mechanism is connected to a computer, which controls the on-off switch based on pre-determined conditions. When the control switch part of the circuit is opened, the ablation generator shuts of immediately. The software in the computer is configured, such that the computer controlled stopping of energy delivery only occurs when patient safety is at risk.
