The device, as modified, will be marketed under the trade name x stoppk and is indicated for treatment of patients aged 50 or older suffering from neurogenic intermittent claudication secondary to a confirmed diagnosis of lumbar spinal stenosis (with x-ray, mri, and/or ct evidence of thickening ligamentum flavum, narrowed lateral recess and/or central conal narrowing).
