Peta RFA Percutaneous Radiofrequency-Assisted Disc Decompression

Peta RFA Percutaneous Radiofrequency-Assisted Disc Decompression

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.
Information

Peta RFA by Invamed is a percutaneous radiofrequency device designed for disc decompression in patients with spinal discogenic pain or mild to moderate disc herniations. By employing targeted RF energy, the system aims to reduce intradiscal pressure and shrink nucleus pulposus tissue, relieving nerve root compression and alleviating back or radicular pain. Delivered via a minimally invasive approach, Peta RFA streamlines procedural time while maintaining patient comfort and maximizing clinical efficacy.

Precise RF Energy Delivery

Utilizes a specialized electrode to transmit radiofrequency waves directly into the disc nucleus, ablating a portion of nucleus tissue without extensive open surgery.

Inserted through a small percutaneous entry, Peta RFA reduces hospital stay, shortens recovery periods, and diminishes scarring compared to traditional surgical discectomy methods.

Lowering intradiscal pressure eases irritation on nerve roots, potentially resolving radicular pain and restoring patient mobility.

Allows surgeons or interventional pain specialists to monitor real-time RF parameters (power, temperature, impedance) for a customized ablation protocol suiting unique disc morphologies.

Ideal for lumbar, cervical, or thoracic discs presenting contained herniations or disc bulges. Especially beneficial in early disc disease stages or as a transitional therapy before open surgery.

  • Large or sequestered disc herniations that require surgical excision
  • Active infections near the puncture site
  • Severe spinal instability or advanced degenerative disc disease unsuited to RF ablation
