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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
66 words
A method of accessing the spine through a site on the anterior of the sacrum, comprising the steps of: introducing an access device through a tissue tract from the surface of the skin to a first site on the anterior of the sacrum; advancing the access device along the anterior surface of the sacrum to a second site; and entering the sacrum at the second site.
Claim 2
Independent Claim
66 words
A method of accessing the spine through a site on the anterior of the sacrum, comprising the steps of: introducing an access device through a tissue tract from the surface of the skin to a first site on the anterior of the sacrum; advancing the access device along the anterior surface of the sacrum to a second site; and entering the sacrum at the second site.
Claim 3
Dependent Claim
40 words
A method of accessing the spine as in claim 1 , wherein the advancing step comprises advancing the distal end of the access device both distally and laterally as the distal end moves along the anterior surface of the sacrum.
Claim 4
Dependent Claim
21 words
