Abstract
Abstract Disclosed are methods of accessing and treating the spine, while minimizing trauma to surrounding tissue. A device is introduced through tissue, to an access point on the spine. The device is thereafter advanced axially within the spine, from the access point across a treatment zone. In one application, the access point is on the anterior surface of the spine, and, in another application, the access point is on the posterior surface of the spine. The lumen created through the spine across the treatment zone may be either substantially linear, or curved.
