EXPANDING INTERVERTEBRAL DEVICE AND METHODS OF USE

摘要

Disclosed is a spinal stabilization device having a plurality of elongate arms having a distal end portion and a proximal end portion, wherein the elongate arms define an interior volume between the distal end portion and the proximal end portion; at least one limit band coupled circumferentially to one or more of the plurality of elongate arms; and a tensioning element positioned within the interior volume. The plurality of elongate arms can transition from a constrained, delivery configuration that is radially contracted and axially elongated to a relaxed, deployment configuration that is radially expanded and axially shortened.
