Systems, apparatus, and methods for treating spinal tissue and other body structures in open and endoscopic spine surgery to relieve symptoms, such as neck or back pain. In particular, the present invention provides methods for the controlled heating of various tissues in or around the vertebral column, including various interspinous tissues, such that spinal ligaments and cartilage surrounding the vertebrae and the facet joints are shrunk or tightened to stabilize the vertebral column of a patient. Thermal energy is applied to the target tissue in a subablation mode of an electrosurgical system to cause shrinkage of the tissue, thereby stiffening the interspinous tissue and stabilizing the vertebral column. In an exemplary embodiment, a high frequency RF voltage can be applied between one or more active electrode(s) and one or more return electrode(s) to heat a target interspinous tissue to within a temperature range at which irreversible shrinkage of the tissue occurs.

A defibrillator having a pair of electrodes for delivering an impedance-compensated defibrillation shock and a method thereof is provided. The defibrillator can be deployed rapidly and effectively with no or minimal clothing and hair removal. To achieve this, one electrode is coupled to a neck region of the patient, whereas the other electrode is coupled to the patient's body. Both attachment areas are easily accessible to the rescuer, thus allowing a minimally trained user to easily deploy the defibrillator to treat the patient. A wide range of energy levels that are safe for the patient can be generated selectively based on the patient impedance. The presence of voids in the electrodes decrease the effective shock impedance of the electrodes, thus allowing the defibrillator to operate at a lower level of energy when delivering the electrical pulse to the victim's heart.
