The Decompression

  • Over 50% of poor surgical outcomes are attributed to
    lateral spinal stenosis1
  • As little as 30% facet joint removal may lead to

iO-Flex: Targeted Decompression from the Inside Out®

iO-Flex® System, a proprietary minimally invasive set of flexible instruments allowing surgeons to target lumbar spinal stenosis during spinal decompression procedures in all three regions of the spine: central canal, lateral recess, and neural foramen.

  • Complete and Thorough Decompression
  • Direct visualization of the thecal sac through a minimally invasive or open incision
  • Patented flexible instruments provide direct decompression in lumbar surgery applications
  • Targets and decompresses bone and soft tissue in all three regions of the spine: central canal, lateral recess, and neural foramen

3-Step Decompression Utilizing the iO-Flex System


Probe deploys across targeted impinging tissue to precisely deliver the wire


Neuro Check® device helps confirm the wire is dorsal to the nerve root


MicroBlade Shaver® instrument performs precision removal of impinging bone and soft tissue

Assessment: Clinical Utility and Versatility

The iO-Flex System may be utilized to perform a direct decompression in a variety of surgical applications to treat Lumbar spinal stenosis.
