Abstract:
An embodiment of the present invention is directed to methods and devices for treating diseases and conditions that change the special relationship between vertebral bodies and intervertebral disks. A method for performing a transpedicular discectomy procedure may include creating a transpedicular channel to a first vertebral body through a first pedicle of a first vertebra; inserting a flexible drill through the transpedicular channel causing the flexible drill to make an approximately 90 degree angle, the flexible drill creating a channel through the first vertebral body into an intervertebral disk; and removing a portion of the intervertebral disk with a laser device. A laser catheter device for use in ablation and removal of intervertebral disk material in a percutaneous transpedicular approach may include an elongated tube comprising a first lumen and a second lumen, the first lumen comprising a fiber optics bundle and the second lumen for evacuation of ablated material; and a Holmium-YAG infrared laser or a laser diode for generating laser energy to the distal end through the elongated tube.
