Thermal ablation cannula / radiofrequency cannula (RF cannula)

The thermal lesion cannula, also known as a radiofrequency cannula, is used in modern medicine for pain management. During the procedure, the cannula is guided to a specifically affected nerve and a stimulation probe is passed through the cannula to the affect site. The tissue is then heated (ablated) denaturing the nerve blocking the pain stimulus. The procedure can be used to treat chronic pain conditions, such as joint or back pain, to achieve long-term relief. This minimally invasive procedure is an effective option for patients whose pain does not respond well to other therapies significantly improving their and quality of life.


Customer requirement:

A cannula with a medically approved coating that is both temperature and puncture resistant for the ablation of tissue.


Our solution:

Based on our years of interdisciplinary manufacturing know-how and close cooperation with our customers, sfm has been able to develop high-quality cannulas with a safe, homogenous, coating. The smooth surface and heel-less transition of the coating help reduce the sensation of pain during the procedure. sfm RF cannula are available in several different overall lengths with various lengths of uncoated tip sections. Some versions have a curved tip design with side opening for the electrode expanding the ablation field.
