This is a technical overview of an INVAMED device within the pain management, spine & algology portfolio. 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
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. 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.
ThermoEdge RFA Platform: Overview
A versatile radiofrequency ablation platform supporting multiple RF ablation applications across pain management and tissue ablation indications.
How It Works and Where It Fits
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. Genicular nerve ablation, or knee RFA, targets the sensory genicular nerves around the knee to address chronic knee pain in selected patients. Thermal RF applies continuous energy to raise nerve tissue temperature and create a heat lesion, while pulsed RF delivers energy in bursts.
Key Considerations
- The literature commonly cites facet RF relief in the range of about 6 to 12 months, but individual duration varies and is not guaranteed.
- Diagnostic nerve blocks are commonly used before radiofrequency ablation to help confirm the pain source, as judged by the clinician.
- Because sensory nerves can regenerate, repeat treatment may be considered over time, based on the return of symptoms.
Frequently Asked Questions
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.
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.
About INVAMED
INVAMED states it maintains a growing portfolio of international patents across its device range. INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development.
Clinical and Technical Context
Generator settings are managed by the operator according to the target and the device instructions for use. The INVAMED Peta RFA System, Nerve is positioned for nerve-targeted thermal lesioning across cervical, thoracic, lumbar, and sacroiliac applications. Generators such as the INVAMED Peta platform provide real-time feedback on temperature and impedance to support controlled energy delivery. 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. 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. INVAMED pain management devices are for use by trained pain specialists under imaging guidance and per the instructions for use. The choice between pulsed and thermal modes is made by the pain specialist for the specific target. The INVAMED Fusion Intraosseous Radiofrequency Ablation System for Spinal Tumors is positioned for this within-bone application. Candidacy and target selection are determined by the treating clinician following assessment. Interventional pain management, sometimes called algology, addresses chronic back, neck, joint, and tumor-related pain that has not responded adequately to conservative measures. The INVAMED Peta platform provides this feedback, and the ThermoEdge RFA Platform sits within the same RF portfolio.
