Epidural adhesiolysis with a navigable catheter under x-ray control
A special guiding needle is introduced under C-arm x-ray visualization through a natural opening in the sacrum (sacral hiatus), through the intervertebral foramen (natural hole from which the nerve root exits), or between segments in the epidural space. A soft navigable catheter with a movable tip is then introduced through the needle. This catheter is able to reach the affected area very precisely, for example an inflamed spinal nerve. It is used for drug administration, for removing small adhesions, and for diagnosing the spinal canal.
