| 20080234690 | Volume measuring intervertebral tool system and method - The invention includes a system and method for the loosening of tissue. In one embodiment, a device for use in an intervertebral tissue removal procedure includes a cannula having a first end portion for insertion into tissue, a feed passage within the cannula, a return passage within the cannula, and a loosening member movable within the feed passage and the return passage and at least partially deployable away from the first end portion of the cannula. | 09-25-2008 |
| 20080243192 | Passive Screw Locking Mechanism - Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate. | 10-02-2008 |
| 20090005870 | Highly Lordosed Fusion Cage - A two-piece fusion cage having opposed interior surfaces, vertical and lateral throughholes adapted to enhance fusion and a dovetail feature mating the opposed interior surfaces. | 01-01-2009 |
| 20090005873 | Spinous Process Spacer Hammock - An interspinous spacer comprising:
| 01-01-2009 |
| 20090054902 | TETHER TENSIONING INSTRUMENT - Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes a tensioning mechanism adapted to couple to a tether extending along a path between at least two bone anchors implanted in adjacent vertebrae. The tensioning mechanism can be adapted to apply a tensioning force to the tether along the path of the tether to thereby move the tether along the path. The device further includes an actuation mechanism movably coupled to the tensioning mechanism such that the actuation mechanism is adapted to effect movement of the tensioning mechanism to control the tensioning force applied to the tether. | 02-26-2009 |
| 20090088789 | Balloon With Shape Control For Spinal Procedures - In intervertebral operative spinal procedures, using separate or pre-attached spreader blocks to control the directional growth of a distracting balloon. | 04-02-2009 |
| 20090248076 | Interspinous Process Spacer Having Tight Access Offset Hooks - An interspinous spacer having a pair of hooks that, upon lateral insertion between opposed spinous process, bear upon the opposed spinous processes. | 10-01-2009 |
| 20090248079 | S-Shaped Interspinous Process Spacer Having Tight Access Offset Hooks - An S-shaped interspinous spacer having a pair of hooks that, upon lateral insertion between opposed spinous process, bear upon the opposed spinous processes. | 10-01-2009 |
| 20100179578 | SPINAL DISC PREPARATION TOOL - A spinal disc preparation tool is provided that includes an elongate shaft having an inner lumen extending therethrough along a longitudinal axis between proximal and distal ends thereof. A lower jaw is located on a distal end of the elongate shaft for receiving tissue and delivering tissue to the inner lumen, and an upper jaw is pivotally movable relative to the lower jaw. The tool can include various features to facilitate removal and/or collection of tissue. | 07-15-2010 |
| 20100249935 | Zero Profile Spinal Fusion Cage - An interbody fusion cage having upper and lower canals for receiving the heads of bone screws that have been pre-installed in opposing vertebral body endplates. The proximal wall of the cage preferably has a vertical slot that communicates with each canal and is adapted to allow access by a screwdriver and tightening of the screws. | 09-30-2010 |
| 20110066192 | Expandable Ring Intervertebral Fusion Device - An expandable tube having a substantially semicircular unexpanded shape is inserted into the disc space after the disc material has been removed therefrom. A plurality of expandable lockable rings are passed over this tube in their unexpanded states and positioned along the anterior edge of the endplates. The tube is then expanded, thereby forcing the rings to expand. The rings hold their final expanded configuration via a one-way locking mechanism. Once sufficient distraction is achieved and the rings locked, the tube is collapsed and removed, thereby leaving the expanded, locked rings behind to support the disc space. | 03-17-2011 |
| 20110066244 | Minimally Invasive Intervertebral Staple Distraction Devices - Multiple, small, staple-like supports are inserted through a small tube into the disc space then rotated into position on the edge of the vertebral bodies. The tooth-like geometry of the proximal and distal faces of these staples mates with the outer edge of the vertebral body, extending past the front of the endplate anteriorly. The staples have teeth that dig into the endplate on the inside of the rim as well. | 03-17-2011 |
| 20110118787 | ARTIFICIAL FACET JOINT - Various methods and devices for replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, and/or other features of a patient's spinal column, are provided. In one exemplary embodiment, the methods and devices are effective to mimic the natural function of the spine by allowing flexion, extension, and lateral bending of the spine, while substantially restricting posterior-anterior shear and rotation of the spine. | 05-19-2011 |
