ABSTRACT:
The present invention provides systems and methods for selectively applying electrical energy to a target location within a patient's brain and spinal cord. The systems and methods of the present invention are particularly useful for treating cerebrovascular diseases, such as vessel occlusion, or for the volumetric removal or ablation of intracranial tumors or Arteriovenous Malformations (AVMs). The method of the present invention comprises positioning an electrosurgical probe or catheter adjacent the target site so that one or more electrode terminal(s) are brought into at least partial contact or close proximity with a body structure within the patient's head or neck, such as tumor tissue or an occlusion within a blood vessel. High frequency voltage is then applied between the electrode terminal(s) and one or more return electrode(s) to volumetrically remove or ablate at least a portion of the body structure in situ. In specific embodiments, the high frequency voltage is sufficient to effect the dissociation or disintegration of organic molecules into non-viable atoms and molecules. Specifically, the present invention converts the solid tissue cells into non-condensable gases that are no longer intact or viable, and thus, not capable of spreading viral or bacterial particles to other portions of the body structure.
