Below is an educational, technical answer to a question many patients and clinicians ask. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. 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
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. 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. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment.
Can radiofrequency ablation be repeated?
Because the treated sensory nerves can regenerate, a radiofrequency procedure may be repeated in appropriate cases when symptoms return. The timing of any repeat treatment depends on the return of pain and the clinician's assessment. Repeat procedures use the same principle of controlled energy delivery through an electrode. Whether and when to repeat is an individualized clinical decision, not a fixed schedule.
What This Means in Practice
Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual. Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed.
Key Considerations
- 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.
- Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician.
Frequently Asked Questions
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.
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
Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician. The specific nerves treated and the extent of lesioning are clinical decisions made under imaging guidance. The decision to treat and the specific level targeted are determined by the pain specialist. Candidacy and target selection are determined by the treating clinician following assessment. Generators such as the INVAMED Peta platform provide real-time feedback on temperature and impedance to support controlled energy delivery. The INVAMED Peta RFA System, Nerve is positioned for nerve-targeted thermal lesioning across cervical, thoracic, lumbar, and sacroiliac applications. 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. The INVAMED Peta RFA System, Nerve supports nerve-targeted thermal lesioning across multiple spinal regions. Generator settings are managed by the operator according to the target and the device instructions for use. 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. The number and location of lesions are planned individually under imaging guidance.
