Abstract: A system for delivering radiofrequency energy to ablate tissue comprises a radiofrequency generator and an intravascular catheter. The catheter includes both a radiofrequency ablation electrode and a temperature sensor within its distal end. Delivery of power to the ablation electrode may then be controlled based on electrode temperature using a cascade control system wherein analog temperature controller adjusts the set point to a secondary power controller. Alternatively, power delivered to the patient can be controlled directly based on a power set point. A sinusoidal RF signal is provided to avoid energy attenuation and the sinusoidal RF signal may be pulsed to avoid buildup of coagulum on the catheter tip while providing high power to create large lesions. A verification circuit checks the continuity of circuits in the catheter.

Abstract: Energy emitting systems are provided which include an adjustable conductive coil configured to generate a magnetic or electromagnetic field focused on a target nerve. The coil includes a central aperture which may be adjustable between a first configuration and a second configuration having a radius greater than the radius of the first configuration. The adjustable or movable nature of the coil allows the conductive coil to conform to, accommodate, or be positioned on a particular anatomical structure of a patient to position the coil in proximity to the underlying target nerve. In certain embodiments, methods of magnetic induction therapy are provided which include positioning a conductive coil relative to a portion of a patient's body by adjusting the central aperture of the coil such that the coil may conform to, accommodate or be positioned on the portion of the patient's body in proximity to the underlying target nerve.

Abstract: An apparatus and method for use in performing ablation of organs and other tissues includes a radio frequency generator which provides a radio frequency signal to ablation electrodes. The power level of the radio frequency signal is determined based on the subject area of ablation. The radio frequency signal is coupled with the ablation electrodes through a transformation circuit. The transformation circuit includes a high impedance transformation circuit and a low impedance transformation circuit. The high or low impedance transformation circuit is selected based on the impedance of the ablation electrodes in contact with the subject tissue. Vacuum level, impedance level, resistance level, and time are measured during ablation. If these parameters exceed determinable limits the ablation procedure is terminated.

Abstract: A method and apparatus for treating tissue using an electrosurgical system. The system includes an electrosurgical system having an RF generator, a treatment electrode electrically coupled to the RF generator and positioned in contact with target tissue to be treated, and a spark gap switch positioned between the RF generator and the target tissue. The spark gap includes a threshold voltage and is configured to prevent conduction of current from the RF generator to the tissue until the voltage across the spark gap reaches the threshold voltage. The method includes the steps of using the RF generator to apply a voltage across the spark gap switch, the spark gap switch causing conduction of current from the RF generator to the target tissue once the voltage across the spark gap reaches the threshold voltage.
