Minimally Invasive Surgical (MIS) Technique and System for Performing an Interbody Lumbar Fusion with a Navigatable Intervertebral Disc Removal Device and Collapsible Intervertebral Device

A technique and system is provided for efficiently, effectively and safely performing an interbody lumbar fusion. The technique and system utilizes: (1) a rotary shaver that provides a shaving cannula; (2) an outflow/insertion cannula which provides a dual purpose cannula; and (3) a fusible balloon which provides a biodegradable intervertebral bag. The patient's disc is shaved and cut out with the shaver while the shavings are sucked out with the dual purpose cannula. Afterwards, the balloon is inserted at the tip of the dual purpose cannula and the balloon is filled with a grafting substance. The balloon assumes the shape of the removed disc. The grafting substance will fuse to the balloon and to the adjacent vertebrae and provide a support where the removed disc was.
