The Cosman ENA Kit is indicated for use for RF heat lesion making for the treatment of pain and functional neurological disorders.

The ENA Kit was designed by Dr. A. O. El-Naggar, MD, Dr. B. S. Nashold, MD, and Dr. E. R. Cosman, PhD*. The ENA Kit contains two electrodes, each having an angled distal tip to facilitate the approach to the anatomy of the nucleus caudalis at the cervicomedullary junction while sparing the spinocerebella tract. The electrodes’ handles enable sure-grip, angulation, and rotation. The ENA-TC(1.2) Electrode has an exposed lesioning tip with 1.2 mm length and 0.25 mm diameter, an insulated segment with 0.6 mm length, and an insulative shoulder The shoulder is to guard against unwanted inward drift of the tip. It is used at the C1-C2 level. The ENA-TC(2.0) Electrode has an exposed lesioning tip with 2.0 mm length and 0.25 diameter, an insulative segment of 0.6 mm length, and insulative shoulder. It is used near the obex. Each Electrode has a thermocouple (TC) temperature sensor at its distal-most point for thermal monitoring of the RF lesioning process. The ENA Kit comes with the CB112-TC Cable to connect the Electrodes to the Cosman RF Generators.

ENA-TC(1.2), Electrode, 1.2 mm;

ENA-TC(2.0), Electrode, 2.0 mm;

CB112-TC, TC Cable;

ENA-CASE, Case for storage and sterilization.

Same as the ENA Kit but with a C112-TC Cable for the Radionics RFG-3C Plus RF Lesion Generator (instead of the CB112-TC).
