For decades, the 16-gauge RRE electrode has been the choice of pain management specialists who desire larger lesions to increase the length of coagulated nerve and reduce sensitivity to nerve position. Now, a 2012 study published in Pain Medicine by Dr. John MacVicar et al. using the RRE electrode5 demonstrates complete relief of chronic neck pain for over 1 year in most patients, and beyond 3 years in many patients treated. Whereas the Cosman RRE has a straight, solid shaft, the new Cosman 16-gauge cannula has curved shaft to facilitate placement and a central lumen for injection.
Radiofrequency heat lesions created clincially using 16-gauge, 10mm tip RF electrodes were found to be 10mm x 10mm x 12mm ellipsoidal post-morterm.1 The reported size of the heat lesions produced by the Baylis®/Kimberly-Clark® Sinergy® cooled RF electrode is 8-10mm spherical.6,7,8 Yet, the price of a disposable 16-gauge RF cannula and electrode is a fraction of the price of a disposable cooled RF electrode system.
These new disposable devices further expand Cosman's broad offering of high quality, steerable, and smooth RF cannula:
- Lengths: 5, 10, 15, 20 cm
- Tip Exposure: 2, 4, 5, 10, 15, 20 mm
- Diameter: 22, 21, 20, 18, 16 gauge
- Straight or Curved
- Sharp or Blunt
New part numbers for curved, sharp, 16-gauge cannulae:
|
Length (cm) |
Tip (mm) |
Gauge (ga) |
Part Number (10/pk) |
| 5 | 6 | 16 | RFK-C5616S-P |
| 5 | 10 | 16 | RFK-C51016S-P |
| 10 | 6 | 16 | RFK-C10616S-P |
| 10 | 10 | 16 | RFK-C101016S-P |
| 15 | 6 | 16 | RFK-C15616S-P |
| 15 | 10 | 16 | RFK-C151016S-P |
Each Cosman RF cannula features an ergonomic hub, a steerable shaft, and specially tapered insulation at the tip to facilitate insertion and maneuvering. The cannula is colored coded by length and is compatible with all Cosman electrodes of matching length, including the reusable Nitinol (TCN), reusable stainless steel (CSK), and disposable (TCD) models.
The Cosman name has been synonymous with innovation and excellence in radiofrequency medicine for 60 years. Bernard J. Cosman founded Radionics and built the first commercial RF lesion generator in 1952. His son, Professor Eric R. Cosman, Sr., Ph.D. of the MIT Physics Department, directed Radionics from 1970 until its sale in 2000. Over that period, the Cosmans created dozens of RF generator models used by thousands of clinicians around the world, and they invented hundreds of RF electrode systems for specific applications in the treatment of neurological diseases, pain, and cancer that revolutionized the minimally-invasive approach to these problems. Today, Dr. Eric R. Cosman, Jr., Ph.D. and the Cosman Medical team continue this unique tradition into a third generation.
