InSWing Interspinous Spacer

The InSWing™ Interspinous Spacer is a decompression solution developed to relieve pain from lumbar spinal stenosis (LSS). This device offers the advantages of a reduced incision size, minimized muscle trauma and preservation of the supraspinous ligament. InSWing offers a less invasive surgical approach, requires minimal or local anesthesia, reduces blood loss, and results in shorter rehabilitation then alternative surgical procedures.

Placed between the spinous processes of the lumbar spine using a unique unilateral approach, innovative InSWing is secured through the deployment of a proprietary double-wing structure resulting in the widening of the spinal canal and decompression of the symptomatic level. Additional stability can be obtained with the application of a band.

Product Highlights

  • Unilateral approach with optimal stability and decreases incision size
  • Supraspinous Ligament is preserved
  • Minimally invasive, shorter hospital stay and recovery, less pain
  • Optional unilateral cord installation
  • Radiolucent and preventing fatigue bone fractures


The InSWing Interspinous Spacer is indicated to relieve leg and back pain due to symptomatic Lumbar Spinal Stenosis (LSS) from levels L1/L2 to L4/L5 with or without neurogenic intermittent claudication. The device can be used in combination with decompressive procedures providing that the spinous processes remained intact.
