Peta RFA for Pain is a radiofrequency ablation device manufactured by INVAMED, designed to help physicians target specific nerves involved in chronic pain signaling. This article explains, in plain language, what the device is intended to do and where it fits within a physician-directed pain management plan.
What Is Peta RFA for Pain?
Peta RFA for Pain is designed to target pain-causing nerves through thermal lesioning, using controlled radiofrequency energy intended to modulate or interrupt nociceptive (pain) signal pathways. It is engineered for use by trained physicians addressing chronic pain believed to originate from the spine, the sacroiliac region, or select peripheral nerve branches. The device is part of INVAMED's broader Pain Management & Spine (Algology) portfolio.
How Does the Device Work?
Like other radiofrequency-based nerve treatment tools, Peta RFA for Pain delivers controlled radiofrequency energy through a specialized electrode positioned near the target nerve, under physician guidance. This energy generates a localized, controlled thermal lesion intended to interrupt the nerve's transmission of pain signals. The system is designed to provide real-time feedback on temperature, impedance, and lesion size, intended to help the treating physician manage energy delivery carefully and reduce the likelihood of unintended tissue effects.
Where Might Physicians Use This Technology?
Physicians may consider Peta RFA for Pain applications including:
- Medial branch nerves associated with facet joint pain in the spine
- Sacroiliac joint denervation, targeting the sensory nerves supplying the SI joint
- Selective peripheral nerve ablation, for appropriately diagnosed peripheral nerve-mediated pain
In each case, the device is generally used only after diagnostic confirmation — such as a positive response to a diagnostic nerve block — has helped establish that a specific nerve or joint is contributing meaningfully to the patient's symptoms.
What Should Patients Understand About This Technology?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Frequently Asked Questions
Is Peta RFA for Pain used only for back pain?
No. While facet joint and SI joint applications in the spine are common, the device is also designed to support selective peripheral nerve ablation for appropriately diagnosed cases, based on physician assessment.
Does the device eliminate the underlying cause of pain?
No. The technology is designed to interrupt pain signal transmission at the targeted nerve rather than treat the underlying structural or degenerative changes that may be contributing to the condition.
Who decides if this device is appropriate for a specific patient?
The decision is made entirely by the treating physician, based on diagnostic evaluation, prior treatment history, and an assessment of the individual patient's overall health and goals.
