This article explains, in educational terms, facet joint radiofrequency ablation — how the technology works and where it fits. Common targets include the medial branch nerves supplying the facet joints of the spine, the sacroiliac region, and peripheral nerve branches such as the genicular nerves around the knee. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Chronic Pain Managed with Interventional Radiofrequency Techniques
RF procedures are generally performed percutaneously under imaging guidance, and modern generators provide feedback on parameters such as temperature and impedance to support safe energy titration. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Common targets include the medial branch nerves supplying the facet joints of the spine, the sacroiliac region, and peripheral nerve branches such as the genicular nerves around the knee.
Facet Joint Radiofrequency Ablation
Facet joint radiofrequency ablation targets the medial branch nerves that carry sensation from the small facet joints of the spine. Diagnostic blocks are often used beforehand to confirm that these nerves are the source of pain, as judged by the clinician. The INVAMED Peta RFA System, Nerve is positioned for nerve-targeted thermal lesioning across cervical, thoracic, lumbar, and sacroiliac applications. The number and location of lesions are planned individually under imaging guidance.
Design and Technical Notes
INVAMED's pain management portfolio centres on radiofrequency lesion generators and electrode systems, organized by the anatomical target and the type of RF energy delivered. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed. INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use.
Key Considerations
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
- Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
- Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual.
Frequently Asked Questions
Are these RF devices CE marked?
Regulatory status such as CE marking and manufacturing standards are stated in the product documentation and depend on local registration by market.
What feedback does the Peta RFA system provide?
INVAMED states the Peta RFA for Pain provides real-time feedback on temperature, impedance, and lesion size to support safe energy titration.
How long does RF ablation relief last?
The literature commonly cites facet-related relief of about 6 to 12 months, but duration varies by patient and target and is discussed with the treating specialist.

Clinical and Technical Context
Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Its use is planned individually as part of a broader oncological and pain management strategy. The number and location of lesions are planned individually under imaging guidance. Thermal RF creates a heat lesion to interrupt pain transmission, while pulsed RF applies energy in bursts intended to modulate the nerve without the same degree of thermal lesioning. RF procedures are generally performed percutaneously under imaging guidance, and modern generators provide feedback on parameters such as temperature and impedance to support safe energy titration. Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures. The INVAMED Peta Radiofrequency Ablation (RFA) for Pain provides controlled radiofrequency energy delivery with real-time feedback on temperature, impedance, and lesion size for safe energy titration. The INVAMED Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors is positioned for this within-bone application.
