This is a technical overview of an INVAMED device within the pain management, spine & algology portfolio. A central technique is radiofrequency (RF) treatment, in which controlled energy is delivered through an electrode to thermally ablate or modulate nerves that transmit pain signals. 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
Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. 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.
Peta Radiofrequency Ablation (RFA) System, Nerve: Overview
Nerve-specific RFA system that identifies and ablates sensory nerves transmitting pain from the spine; indicated for facet joint arthropathy in cervical, thoracic and lumbar regions, sacroiliac joint pain syndromes, and chronic axial back or neck pain unresponsive to conservative therapy.

How It Works and Where It Fits
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. Facet joint radiofrequency ablation targets the medial branch nerves that carry sensation from the small facet joints of the spine. A radiofrequency lesion generator supplies and controls the energy delivered through the electrode during a pain procedure.
Key Considerations
- Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
- INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use.
- Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual.
Frequently Asked Questions
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.
Can RF ablation be repeated if pain returns?
Because treated sensory nerves can regenerate, a repeat procedure may be considered in appropriate cases; the timing is an individualized clinical decision.

Clinical and Technical Context
The INVAMED Peta RFA System, Nerve is positioned for nerve-targeted thermal lesioning across cervical, thoracic, lumbar, and sacroiliac applications. Its use is planned individually as part of a broader oncological and pain management strategy. 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. Candidacy and target selection are determined by the treating clinician following assessment. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment.
