Abstract
A probe system and method for treating an intervertebral disc of a patient are disclosed. A probe has a cannula having an open end defined at a distal end and adapted to couple to a power source. A stylet fits into the cannula so that a distal end of the stylet occludes the open end at the distal end of the cannula. The probe system also includes a pressure monitoring apparatus coupled to the stylet, with the stylet including a pressure sensor in proximity to the distal end of the stylet. The pressure sensor communicates with the pressure monitoring apparatus to measure the pressure of the intervertebral disc. The power source delivers power to the distal end of the cannula, causing heating of the disc when the distal end of the cannula is disposed within the disc, thereby relieving patient pain associated with the disc.
