This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating pain management, spine & algology devices. 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
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. 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.
Regulatory Status and Manufacturing
For pain units and distributors, INVAMED positions a radiofrequency portfolio spanning spinal, sacroiliac, knee, and intraosseous applications. The range includes the Peta RFA for Pain with real-time temperature, impedance, and lesion-size feedback, the Peta RFA System, Nerve for cervical, thoracic, lumbar, and sacroiliac targets, the Peta RFA for Knee Pain, the Fusion Intraosseous RFA System for Spinal Tumors, and the ThermoEdge RFA Platform. Electrode and cannula dimensions, generator settings, and compatible accessories are specified in the product documentation rather than inferred. Procurement teams should confirm local regulatory registration and indication status, which vary by market.
Portfolio and Sizing
Within this category, INVAMED lists devices such as Peta Radiofrequency Ablation, Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors, ThermoEdge RFA Platform. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
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.
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
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.
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.
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.

Clinical and Technical Context
Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. The choice between pulsed and thermal modes is made by the pain specialist for the specific target. The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed. 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. Generators such as the INVAMED Peta platform provide real-time feedback on temperature and impedance to support controlled energy delivery. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. The specific nerves treated and the extent of lesioning are clinical decisions made under imaging guidance. The INVAMED Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors is positioned for this within-bone application.
