Method and apparatus for spinal stabilization

摘要

A method and apparatus of limiting at least one degree of movement between a superior vertebrae and an inferior vertebrae of a patient includes advancing a distal end of a stabilization device into a pedicle of the inferior vertebrae. A proximal portion of the stabilization device is positioned such that the proximal portion limits at least one degree of movement between a superior vertebrae and an inferior vertebrae by contacting a surface of the superior vertebrae.

主权项

1. A spinal stabilization device, comprising:
an elongate body, having a proximal end and a distal end; a distal anchor on the distal end of the elongate body; a proximal anchor moveably carried by the elongate body, the proximal anchor having an enlarged proximal flange and a wall that is radially adjustable with respect to the elongate body, the wall extending from the proximal flange to a distal end of the proximal anchor, and the wall defining a cavity configured to be selectively inflated or deflated after the proximal anchor is coupled to the elongate body; wherein the wall comprises a valve configured to allow entry of an inflation material into the cavity.
