摘要:
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.
摘要:
An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.
摘要:
An intervertebral fusion device comprising inferior and superior fusion cage devices that provide an ability to correct spondylolisthesis via in-situ adjustment.
摘要:
An anti-adhesion sheet for placement upon the anterior wall of a vertebral body, wherein the sheet has a radius of curvature that is less than that of the anterior wall of the vertebral body.
摘要:
A self-retaining neural retraction clip, preferably having controlled retraction level and an off-set retraction means. This device can reduce operative site clutter to enhance disc access while providing consistent and stable dural retraction.
摘要:
An in-situ formed laminoplasty implant comprising an expandable bag containing a flowable, hardenable composition, wherein the implant may be shaped to act as a laminoplasty strut and be rigidly connected to a prepared lamina space.
摘要:
The use of a memory metal mesh stent as a retractor in a lateral approach to the spine. The expanded stent is used as a conduit through which an implant can pass. This advance is predicated upon the appreciation that modern stent implants have diameters that are large enough to accommodate passage of an intervertebral spinal implant therethrough.
