This is a typical interspinous flexion device like the “X-stop” among others. This device is jammed between the spinous processes to force flex the vertebral segment. Flexion causes the canal to open up (see https://neckandback.com/conditions/lumbar-spinal-stenosis-central-stenosis/ to understand this process.
I am not a fan of any of these devices as they can cause trouble by flexing the segment that is designed to be in lordosis (the reverse of flexion) throwing off the normal alignment and really don’t solve the problem to begin with. They commonly fail as they erode into the spinous processes causing a loss of the flexion they were designed to maintain.
Whatever disorder you have, in my opinion you would be better off to take care of the problem that causes the nerve compression by directly decompressing the nerve.
