This article compares two approaches side by side to clarify how they differ in principle and practice. 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
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. 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.
Radiofrequency ablation vs Spinal cord stimulation: Key Differences
Radiofrequency ablation lesions or modulates specific pain-transmitting nerves and does not leave an implanted device behind. Spinal cord stimulation instead uses an implanted system to deliver electrical stimulation to the spinal cord for pain control. The two occupy different places in the pain management pathway and address pain through different mechanisms. Selection depends on the pain diagnosis and is determined by the specialist; INVAMED's portfolio here centres on RF systems.
How INVAMED Supports Both Approaches
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. For pain units and distributors, INVAMED positions a radiofrequency portfolio spanning spinal, sacroiliac, knee, and intraosseous applications. Procurement teams should confirm local regulatory registration and indication status, which vary by market.
Key Considerations
- 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.
- 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
The INVAMED Peta Radiofrequency Ablation (RFA) for Pain provides controlled radiofrequency energy delivery with real-time feedback on temperature, impedance, and lesion size for safe energy titration. Candidacy and target selection are determined by the treating clinician following assessment. Its use is planned individually as part of a broader oncological and pain management strategy. Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician. 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. 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 specific nerves treated and the extent of lesioning are clinical decisions made under imaging guidance.
