Radiofrequency (RF) Ablation for pain has been available since the mid-1970s and has largely remained unchanged with most of the treatments being done with standard 18 or 20 gauge needle electrodes. These simple needles provide a small heat generated lesion which is intended to create a neurotomy, which describes ablation (separation) to the nerves responsible for sending pain signals to the brain.
The unmet clinical need for the physicians who do these treatments was a cost effective, easy to use, RF cannula that would provide a large and optimally shaped heat lesion to treat pain. A larger lesion has significant clinical value, as it provides more area for the nerve ablation (neurotomy) to be complete.
Nimbus provides up to 4x larger lesion than traditional 18 or 20 gauge needles. This large lesion is comparable in size and volume to cooled RF devices, but at a much lower cost, shorter procedure time and improved efficiency.
