This book introduces a new medical device, the ZiNeu catheter, and explains its use for the non-surgical interventional treatment of degenerative spinal disease, including spinal stenosis. In particular, the device can directly alleviate stenosis of the intervertebral foramen or central canal and perineural adhesions, resulting in reductions in back pain, leg pain, and neurogenic claudication. The ZiNeu device was invented by the author and the JUVENUI company. It now has CE certification and is exportable to Europe. The book opens by explaining the concepts of epidural balloon decompression and adhesiolysis and outlining the types and features of the ZiNeu catheter. The full range of procedures using the ZiNeu series, ZiNeuF series, and the ZiNeuF03 catheter is then described and illustrated, and guidance provided on key aspects of decision making and post-procedure management. The book will be of interest to all specialists in pain management.
