Spinous process fixation apparatus

摘要

An implantable device and method for fixation of spinous processes is presented. The device has first and second spaced plates configured for attachment to portions of adjacent spinous processes. The device can also have an implant configured for insertion between two adjacent spinous processes, but need not necessarily. The method has the steps of assembling the components of the implantable device and otherwise inserting them into position onto, between, and/or adjacent two desired spinous processes.

1. An implantable device for fixation of spinous processes, comprising:
first and second spaced plates, the first plate having a first surface facing a second surface of the second plate; and a post having a longitudinal length; a means to translate the first plate along at least a portion of the longitudinal length of the post, move the first plate polyaxially with respect to the post, and directly attach the first plate to the post at a desired position along it's longitudinal length to fix its position and orientation relative to the post; and a means to translate the second plate along at least a portion of the longitudinal length of the post, move the second plate polyaxially with respect to the post, and directly attach the second plate to the post at a desired position along its longitudinal length to fix its position and orientation relative to the post.
