Abstract
A device and method for a minimally invasive surgical implantation to reduce radicular symptoms by inserting an expandable cervical distraction implant in the facet joint and distracting the adjacent cervical vertebrae to increase the foraminal dimension. The implant, when positioned in the cervical facet joint, expands via delivery of an inflation medium to increase the space between the vertebrae, thereby increasing the foraminal area or dimension, and reducing pressure on the nerves and blood vessels of the cervical spine.
