Disclosed herein are devices for minimally invasive vertebral augmentation and restoration of spinal lordosis using a steerable cannula assembly. When deployed, the articulating cannula, including an outer cannula and an inner cannula extending into a central lumen of the outer cannula and coupled to each other at their distal ends, can be manipulated to curve/bend the body of the articulating cannula. This manipulation is used to create a void within the interior body and may also be used to control delivery of a treatment element to the interior body.

Steerable needle assembly for use in vertebral body augmentation

A method of performing a procedure on an intervertebral disc includes inserting a cannulated delivery tube through an opening in an annulus fibrosus of the intervertebral disc, positioning an expandable portion of the tube within the opening in the annulus fibrosus, expanding the expandable portion into contact with the annulus fibrosus about the opening to create a seal between the expandable portion and the annulus fibrosus, performing a procedure through the cannulated delivery tube within the annulus fibrosis, removing the tube, and closing the opening in the annulus fibrosus.

Nucleus augmentation delivery device and technique

A device intended for the treatment of spinal stenosis. This device is an inter-spinous spacer that is introduced through a single posterior incision. It uses a single piece insertion technique with a unilateral approach. The surgeon does not need to access the opposite side of the spinous process. It allows the user infinite adjustability in distraction height with a single locking mechanism.

Crossover spinous process implant

An intervertebral connection system wherein the bone anchor has a helical configuration.

Intervertebral ligament having a helical bone fastener

The invention provides a device and technique to seal an annular defect of an intervertebral disc, determine the in-situ volume of nucleus pulposus material removed, for example from a discectomy of a herniated disc, and facilitate injection of nuclear replacement material.

An intervertebral connection system wherein the bone anchor has a helical configuration, and includes: a) a conformable synthetic ligament having a first end portion and an intermediate portion, b) an anchor having a central axis which is axially implantable into a bone in a patient's body, the anchor comprising:
