Cosman radiofrequency (RF) cannulae are used with thermocouple electrodes, such as the Cosman CSK, TCN, TCD electrodes, for temperature-controlled RF lesioning for the treatment of pain. RF cannulae are typically used to access nervous structures around the spinal, such as the medial branch, dorsal root ganglion, sympathetic chain, and gray ramus communicans. Or, they can be used to target more peripheral nerves such as the suprascapular, splanchnic, and inferior calcaneal. Anesthetics, steroids, contrast and other fluid agents can be injected through a cannula's hollow interior, which also accepts an electrode for RF lesioning.
Cosman RF cannulae come in a wide variety of shapes and size to suit doctor preference and clinical objectives:
- 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
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.
