20100280616 | MINIMALLY INVASIVE CORPECTOMY CAGE AND INSTRUMENT - An assembly comprising an expandable corpectomy cage and an insertion instrument, wherein the expandable cage comprises an instrument attachment features, including mating holes on the sides of the outer sleeve, and a ball-shaped pocket on the endplate of the inner sleeve, and the insertion instrument features a tuning-fork shaped holder, which attaches to the mating holes on the implant's outer sleeve using small bosses which mate with the holes under the spring tension of the fork, and a lever with a spherical end that mates with the ball-shaped pocket in the inner sleeve endplate. | 11-04-2010 |
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 |
20110144753 | Bellows-Like Expandable Interbody Fusion Cage - An interbody fusion device having an accordion-like structure, wherein the device in inserted into the disc space in its collapsed configuration and then expanded into its expanded configuration by compressing the accordion-like portion of the device. In some embodiments, a pre-formed tube with an accordion-like structure over a portion of its length is inserted in a relaxed (collapsed) configuration, giving the tube a minimum possible diameter. This tube has a cable running through it that is fixed to a distal end portion of the tube and extends past the proximal end portion of the tube to the outside of the patient. Once the tube is positioned on the rim of the endplate, the proximal end of the cable is pulled, thereby tensioning the cable and causing the accordion portion of the tube to become shorter in length but larger in diameter. | 06-16-2011 |
20130178941 | 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. | 07-11-2013 |
20140163686 | 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. | 06-12-2014 |
20140172105 | Polyaxial Articulating Instrument - A polyaxial instrument suitable for preparing the intervertebral disc space of a patient through an anterior, posterior, transforaminal or anterolateral approach. The trial can be partially inserted into a disc space and then its angle adjusted to ease its further insertion into the disc space. The trial work tip can be interchangeable with the working tip of another type of instrument such as a curette, a rasp, a spreader, a shaver, a cobb elevator, a penfield, a woodson, a chisel and an osteotome. | 06-19-2014 |
20150018953 | MINIMALLY INVASIVE CORPECTOMY CAGE AND INSTRUMENT - An assembly comprising an expandable corpectomy cage and an insertion instrument, wherein the expandable cage comprises an instrument attachment features, including mating holes on the sides of the outer sleeve, and a ball-shaped pocket on the endplate of the inner sleeve, and the insertion instrument features a tuning-fork shaped holder, which attaches to the mating holes on the implant's outer sleeve using small bosses which mate with the holes under the spring tension of the fork, and a lever with a spherical end that mates with the ball-shaped pocket in the inner sleeve endplate. | 01-15-2015 |
