Electromagnetic scalpels for use on biological tissue. The devices accomplish the tasks of tissue heating, ablation, and even cauterization without electrodes, by directing electromagnetic energy to the tissue. The structure of one of the novel devices consists of four separate "U" -sphaped ferrite cores (30, 32, 34, 36) oriented at 90 degrees to each other, each with one of their respective legs in contact and parallel to the other three, and with their respective "U" openings facing the same way. Wrapped around the four legs in contact is a single winding (28) of conductive metal with the winding filling the spaces formed by the "U" -shaped cores. |
