Peta Mechanical Percutaneous Disk Decompression by Invamed is an innovative, single-use system that enables mechanical nucleus removal via a percutaneous approach. Designed to relieve discogenic pain and address contained disc herniations, this mechanical device uses cutting and suction or nibbling mechanisms (depending on the specific SKU) to precisely extract nucleus pulposus tissue. By preserving annular integrity, it promotes faster patient recovery and lowers the risk of complications commonly associated with more invasive spine surgery. Minimally Invasive Percutaneous Access
Deployed through a small-diameter cannula or introducer, requiring only a minimal incision.
Reduces postoperative discomfort, scarring, and risk to adjacent anatomical structures compared to open discectomies.
Mechanical Debulking Mechanism
Utilizes a cutting, nibbling, or auger-like tip to remove nucleus material effectively from within the disc.
Real-time tactile feedback helps the operator gauge disc removal progress, preventing over-resection.
Precise Disc Clearing & Pain Relief
Controlled resection of excess nucleus diminishes intradiscal pressure, offering symptomatic relief for radicular pain or mild degenerative disc disease.
Preserves annular stability, reducing re-herniation risk relative to more aggressive resection.
Single-Use, Sterile System
Disposable device ensures consistent performance and removes the need for elaborate reprocessing or repeated sterilization cycles.
Each kit is individually packaged sterile, facilitating safe, efficient OR workflow and reducing infection risk.
Versatile Indications
Primarily intended for lumbar disc decompressions (L4-L5, L5-S1), though suitable for certain cervical or thoracic segments where contained herniations exist.
Ideal for patients with mild-to-moderate disc prolapse, discogenic back pain, or radicular symptoms not fully resolved with conservative treatments.
