The KCTE Kit is indicated for use in RF heat lesion making procedures for the relief of pain. The KCTE Kit was designed by Dr. Yucel Kanpolat, MD and Dr. Eric R. Cosman, PhD.* It contains a KCTE-TC-S Electrode with a straight RF tip, and a KCTE-TC-C Electrode with a curved RF tip. Each Electrode has a sharpened exposed tip having 0.27 mm tip diameter and 1.8 mm tip length. They both have a built-in thermocouple (TC) temperature sensor in the RF tip for fast-responding, accurate monitoring of the RF heating process. Their small RF tips can produce a discrete lesion volume in the


lateral spinothalamic tract. Both Electrodes have the KCTE-SC Sizing Clamp on their hub for adjustability of the RF tip extension beyond the tip of the KCTE-C Spinal Needle (as shown in the figure). The Spinal Needle is introduced percutaneously, and provides a guide for the KTCE-CT Electrode. The Sizing Clamp has a gasket to reduce CSF leaks, and the Electrode has millimeter markings on its hub to adjust tip extension. The Kit comes with three KCTE-C Spinal Needles with stylets, each having a 20 gauge, 3½ inch long shaft and 40 degree bevel point. The CB112-TC Cable connects the KCTE-TC Electrodes to the Cosman RF Generator.
