Abstract: An electrosurgical system comprises a return electrode that includes a conductive element and a return conductor that forms a capacitive electrical connection with the conductive element. The conductive element is completely encompassed by one or more pads so that the conductive element is not exposed and so that the return electrode does not include an externally exposed electrical connection.

Abstract: A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.

Abstract: A system and method for the safe delivery of treatment energy to a patient, which includes verification of system integrity before, during, or after the delivery of treatment energy and provides several mechanisms for rapid termination of the delivery of potentially harmful energy to the patient when a fault condition in the device and/or system is identified. The system may include an energy generator having processing circuitry to determine if there is a fault condition in the system and to automatically terminate a delivery of treatment energy when the processing circuitry determines there is a fault condition. The method may generally include performing a series of pre-checks, synchronizing a treatment energy delivery to the proper segment of the heart's depolarization pattern, configuring the system for treatment energy delivery, delivering the treatment energy, and performing post-treatment evaluation.

Abstract: An electrode structure for a distal tip of an electrosurgical instrument that enables efficient delivery of radiofrequency (RF) energy in a forward (distal) direction and uniform delivery of microwave energy for ablation in a region surrounding the distal tip. The instrument comprises a tip body having a first electrode and a second electrode, where the second electrode is spaced from the first electrode exposed dielectric material. The first electrode is connected through the tip body to an inner conductor of a coaxial feed. The second electrode is electrically connected to the outer conductor of the coaxial feed by a field-shaping conductive structure formed in or on the tip body. The field-shaping conductive structure is configured to shape a radiation profile of microwave energy emitted from the tip body.
