Below is an educational, technical answer to a question many patients and clinicians ask. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. 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
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. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. 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.
What are the side effects of radiofrequency ablation?
Reported side effects can include temporary soreness at the treatment site, transient numbness, or a short-lived increase in pain before relief develops. Because the technique places an electrode near nerves, the instructions for use describe the relevant risks and precautions. Generators with temperature and impedance feedback, such as the INVAMED Peta platform, are designed to support controlled energy delivery. The full risk profile is detailed in the device documentation and should be reviewed with the clinician.
What This Means in Practice
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. Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
Key Considerations
- INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use.
- 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.
Frequently Asked Questions
What is the regulatory status of these RF devices?
Regulatory status such as European market authorization and manufacturing standards are stated in the product documentation and depend on local registration by market.
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.
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.

Clinical and Technical Context
The INVAMED Peta RFA System, Nerve supports nerve-targeted thermal lesioning across multiple spinal regions. Its use is planned individually as part of a broader oncological and pain management strategy. Candidacy and target selection are determined by the treating clinician following assessment. Generator settings are managed by the operator according to the target and the device instructions for use. Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician. The choice between pulsed and thermal modes is made by the pain specialist for the specific target. The number and location of lesions are planned individually under imaging guidance. 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.
