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. 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.
How long does radiofrequency ablation last?
Radiofrequency ablation is intended to interrupt pain signals for a period, and the literature commonly cites relief in the range of about 6 to 12 months for facet-related procedures. The duration varies between patients and depends on the target treated and individual factors. Because sensory nerves can regenerate over time, symptoms may gradually return, and repeat treatment is sometimes considered. Expected duration for an individual is best discussed with the treating pain specialist.
What This Means in Practice
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. 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.
- 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
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.
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.

Clinical and Technical Context
The choice between pulsed and thermal modes is made by the pain specialist for the specific target. The INVAMED Peta Radiofrequency Ablation (RFA) for Knee Pain is positioned specifically for this knee application. 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. Its use is planned individually as part of a broader oncological and pain management strategy. 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. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. 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. 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 decision to treat and the specific level targeted are determined by the pain specialist. The INVAMED Peta RFA System, Nerve is positioned for nerve-targeted thermal lesioning across cervical, thoracic, lumbar, and sacroiliac applications.
