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
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. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures.
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
- 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.
- INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use.
Frequently Asked Questions
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.
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.
Are these RF devices CE marked?
Regulatory status such as CE marking and manufacturing standards are stated in the product documentation and depend on local registration by market.

Clinical and Technical Context
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. Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms. Its use is planned individually as part of a broader oncological and pain management strategy. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. 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. 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.
