This article explains, in educational terms, intraosseous radiofrequency ablation for spinal tumors — how the technology works and where it fits. 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. 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
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. 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. 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.
Intraosseous RF Ablation for Spinal Tumors
Intraosseous radiofrequency ablation delivers RF energy within bone to treat certain painful spinal tumor lesions. It is a targeted technique intended to address tumor-related pain and local disease within the vertebral body, as determined by the treating team. The INVAMED Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors is positioned for this within-bone application. Its use is planned individually as part of a broader oncological and pain management strategy.
Design and Technical Notes
INVAMED's pain management portfolio centres on radiofrequency lesion generators and electrode systems, organized by the anatomical target and the type of RF energy delivered. Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician. 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.
- Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures.
Frequently Asked Questions
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.
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.
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
Generator settings are managed by the operator according to the target and the device instructions for use. Whether an RF procedure is appropriate, and which target is selected, is a clinical decision made by a pain specialist after diagnostic assessment. 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. The specific nerves treated and the extent of lesioning are clinical decisions made 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. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. Real-time feedback on temperature, impedance, and lesion size is intended to support safe energy titration during RF procedures. Manufacturer descriptions reflect device design intent rather than a guaranteed outcome for any individual.
