This is a technical overview of an INVAMED device within the pain management, spine & algology portfolio. 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
Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. 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.
Peta Radiofrequency Ablation (RFA) for Pain: Overview
RF lesion generator platform that targets pain-causing nerves through controlled thermal lesioning, modulating or ablating nociceptive pathways to reduce chronic pain in the spine, sacroiliac region or peripheral nerve branches.

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. Thermal RF applies continuous energy to raise nerve tissue temperature and create a heat lesion, while pulsed RF delivers energy in bursts.
Key Considerations
- Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician.
- Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual.
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
Frequently Asked Questions
Does INVAMED make a system for knee nerve ablation?
Yes. The Peta Radiofrequency Ablation (RFA) for Knee Pain is positioned specifically for genicular (knee) nerve applications.
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.
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.

Clinical and Technical Context
Its use is planned individually as part of a broader oncological and pain management strategy. Generator settings are managed by the operator according to the target and the device instructions for use. Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms. The decision to treat and the specific level targeted are determined by the pain specialist. The INVAMED Peta Radiofrequency Ablation (RFA) for Knee Pain is positioned specifically for this knee application. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed. 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.
