Methods and devices for transpedicular discectomy
First Claim
1. A method for performing a transpedicular discectomy procedure, the method comprising the steps of:
- 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.

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 percuntaneous 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.

41. A laser catheter device for use in ablation and removal of intervertebral disk material in a percuntaneous transpedicular approach, the device comprising:
-
an elongated tube having a distal end and a proximal end;
the 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 laser for receiving the elongated tube at the proximal end, the laser for generating laser energy to the distal end through the elongated tube;
wherein the laser catheter device removes a portion of an intervertebral disk wherein the laser catheter device is inserted through a transpedicular channel of a vertebral body through a pedicle of a vertebra. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
