Peta Radiofrequency Ablation (RFA) for Pain

A precision-targeted system designed to deliver controlled radiofrequency energy for nerve ablation, effectively reducing chronic pain by disrupting pain signal transmission while minimizing impact on surrounding tissues.

Peta Radiofrequency Ablation (RFA) for Pain by Invamed provides an effective solution to target pain-causing nerves through thermal lesioning. Engineered for precision and safety, this system uses controlled radiofrequency energy to modulate or ablate nociceptive pathways, thereby reducing chronic pain in the spine, sacroiliac region, or peripheral nerve branches. By delivering heat in accurate, tissue-selective zones, Peta RFA promotes long-term pain relief without significant damage to surrounding structures.

Targeted Nerve Lesioning
  • Transmits radiofrequency energy through a specialized electrode placed near the pain-generating nerve, creating a thermal lesion that blocks nerve conduction.
  • Particularly effective for medial branch nerves in facet joint pain, sacroiliac joint denervation, or selective peripheral nerve ablation.
  • Real-time feedback on temperature, impedance, and lesion size helps clinicians titrate energy delivery safely.
  • Minimizes the risk of over-lesioning or collateral tissue injury, especially around delicate neural structures.
  • Inserted via a small-gauge cannula or needle under fluoroscopic or ultrasound guidance, limiting postoperative discomfort and scarring.
  • Rapid procedure time fosters quick patient recovery, often performed as an outpatient or day-surgery setting.
  • Chronic back and neck pain due to facet joint arthropathy, discogenic issues, or post-surgical syndrome.
  • Sacroiliac (SI) joint pain, cervicogenic headaches, or neuropathic conditions where nerve conduction is implicated in pain.
  • Ablation results can last from 6 to 24 months depending on nerve regeneration patterns and patient factors.
  • Repeat procedures can be performed if pain recurs without major compromise to surrounding tissues.
