TransDiscal™ System
Bipolar, Cooled RF for Intervertebral Disc Biacuplasty
www.transdiscal.com

The TransDiscal™ System is taking disc treatments to a new level. It uses a bipolar approach in conjunction with internally water-cooled radiofrequency (RF) probes to coagulate while decompressing disc material in order to treat symptomatic patients with discogenic pain and contained herniated discs.

Straightforward Probe Placement
The introducers are inserted straight inside the disc without the need for steering a flexible catheter. The stylets provide audio-guided impedance monitoring to assist in identifying the annulus and nucleus. Under fluoroscopy, two introducers are placed bilaterally in the posterolateral disc and the TransDiscal™ probes are then inserted into the introducers.

Temperature Sensors
The TransDiscal™ System includes four temperature sensors: two at the end of each probe tip and two placed to monitor peripheral disc temperature.

Water-Cooled RF
Each TransDiscal™ probe is independently and internally water- cooled allowing RF energy to be delivered with greater power to heat a larger volume of disc tissue while eliminating overheating of tissue local to the electrodes. Cooling also eliminates tissue adherence to the probes. The cooling system-- maintains and balances the temperatures in each probe to the desired set temperature.

Bipolar RF
There are electrodes at the end of the TransDiscal™ Probes which are placed bilaterally in the posterior of the disc. The RF energy is applied and directed through the disc between the two TransDiscal™ probe electrodes. This concentrated energy results in tissue heating around and between the electrodes.

Ideal Therapeutic Zone
The bipolar RF application combined with internal water cooling allows tissue to be heated within an ideal range for ablating nociceptors. This temperature can be altered by changing the parameters on the generator. The end result is a large, reproducible lesion within a significant volume of the posterior of the disc.
