The electromagnetic field focusing system is capable of sharply focusing induced current resulting in pinpoint heating of tissue. This heat can cut and vaporize tissue while simultaneously coagulating vessels. This is a report on the first 15 consecutive neurosurgical cases where this system was used for tumor excision. The system was found to be an effective and safe surgical tool. It functioned effectively, even under saline and cerebrospinal fluid and through narrow openings during stereotactic microsurgical procedures.
