This is a technical overview of an INVAMED device within the pain management, spine & algology portfolio. 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. 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. 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. 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.

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. Rhizotomy is a term used for the interruption of specific sensory nerves to reduce pain transmission, and RF is one way to achieve it. A radiofrequency lesion generator supplies and controls the energy delivered through the electrode during a pain procedure.
Key Considerations
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
- The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed.
- Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician.
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.
Who decides if radiofrequency ablation is appropriate?
A qualified pain specialist decides based on individual assessment and diagnostic blocks; this article is educational and not a treatment recommendation.
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.

Clinical and Technical Context
Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures. The INVAMED Peta platform provides this feedback, and the ThermoEdge RFA Platform sits within the same RF portfolio. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed. The choice between pulsed and thermal modes is made by the pain specialist for the specific target. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. 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. The INVAMED Peta Radiofrequency Ablation (RFA) for Knee Pain is positioned specifically for this knee application. 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.
