The radiation spectrum is reviewed to identify Ellman's technology at the frequency of 1.7MHz and 4.0 MHz. All modalities except of bipolar are at 4.0 Mhz, the frequency clinically proven to produce the least amount of lateral heat. The bipolar modality functions at 1.7 Mhz for additional coagulation.
The Electromagnetic Spectrum represents forms of energy propagated in waves.             Standard ESU's and low frequency RF products occupy a band ranging between 100kHz to 500kHz. These frequencies emit energy in the form of heat. Resulting tissue effects are inconsistent and without absorption control.
  Ellman's patented technology includes the frequencies of 1.7MHz-4.0MHz which is a pure radiosignal range. Absorption of this frequency is by the water component of cells. Surface cell absorption produces controlled depth of penetration and minimal cellular alteration. (see absorption chart).

  Fresh brain tissue measuring 2.0 x 1.0 x 1.0 cm in largest dimension was submitted post surgical harvest. Histologic evaluation of surgical incision created by 4.0MHz radiofrequency technology was requested by the surgeon. Microscopic evaluation of the area of radiofrequency electrosurgical incision shows minimal superficial changes measuring from 10 - 20 microns thickness.
  This technology has recenlty been used to separate conjoined twins at Montefiore hospital in New York.
