An integrated catheter shaft with a guidewire and a radio frequency wire is used in a catheter to deliver radio frequency energy to a treatment site. The small entry wound and the long integrated catheter shaft allows a user to thread the shaft along a tortuous route along a spinal canal to reach a treatment site while causing a minimal amount of trauma to the patient.
