What We Do

Radiofrequency Devices for Pain Management and Neurosurgery

Cosman Medical offers a comprehensive range of RF generators, electrodes, and cannulae for interventional anesthesiology, podiatry, and neurosurgery, including many unique electrode kits for special applications.  No other RF manufacturer can match Cosman’s focus, expertise, and history in radiofrequency medicine.  Cosman’s products are designed and manufactured at our own facility in the United States to ensure superior quality control, rapid customer service, and manufacturing cost savings that we pass on to our customers.  Through personal involvement in academic research and education, Cosman is able to provide clinicians with the very latest in radiofrequency technology.  With 60 years of pioneering history in radiofrequency medicine and unmatched technical expertise, Cosman can offer your practice the best in radiofrequency technology and clinical customer support.


Why Choose Cosman Radiofrequency?

As a customer of Cosman Medical, you can expect superior customer service, competitive pricing, and financing options tailored to your fiscal constraints.  In our products, you can expect high quality construction, exceptional ease of use, and superior reliability.  As time goes on and as your practice grows, you can expect our product line to keep apace of and even lead the latest technical developments, both ergonomic and scientific.  For example, our four-electrode G4 generator not only incorporates touch screen, wireless remote, database technology to improve its usability, but also incorporates patent-pending technology for efficient heating of multiple electrodes and the widest range of Pulsed RF (PRF) settings available in any generator. Our sacroiliac joint pain solution, the Palisade kit, is not only easy to use and cost effective, but also incorporates the latest science on RF lesion size to produce a lesion zone that conforms to patient anatomy efficiently.  Our RF cannulae not only comes in a wide variety of sizes to suit different target anatomy, but are also produced with advanced manufacturing technology that both smooths the insulation for easier maneuvering and reduces prices.


Radiofrequency in Medicine

Radiofrequency nerve ablation is used by interventional anesthesiologists to treat chronic back and neck pain, including pain from facet joint dysfunction, sciatica, nerve impingement, intervertebral disc dysfunction, sacroiliac joint dysfucntion, headaches, postoperative pain, complex regional pain syndrome (CRPS), reflex sympathetic dystrophy (RSD), and other disorders.  Podiatrists employ the same technology to treat intractable pain due to foot and ankle disorders, including plantar fasciitis and Morton’s Neuroma.  Neurosurgeons employ radiofrequency in the brain to treat movement disorders such as Parkinson’s Disease, essential tremor, and spasticity.  Neurosurgeons also use RF to treat severe, intractable pain such as that arising from end-stage cancer (cordotomy), nerve root avulsion injury (DREZ and DREZ nucelus caudalis), and trigeminal neuralgia (PSR).

Radiofrequency is most often used in its “thermal” form, whereby high intensity RF currents heat target tissue near the RF electrode to destructive levels.  In pain management, the target tissue may be a nerve that carries painful impulses.  Radiofrequency is also used in a “pulsed” form, whereby RF currents are delivered in short bursts and controlled such that the measured gross tissue temperature does reach levels expected to product thermal damage. Nerves adjacent to points of high curvature on a PRF electrode’s surface are intermittently subjected to transient temperature spikes within the neurolytic range, whereas nerves in the gross vicinity of the PRF electrode are exposed principally to high electric fields, which may produce adisruptive or neuromodulatory effect.
