Abstract:
1. An apparatus, comprising: an implant member having a cylindrical portion and a saddle portion, at least a portion of the cylindrical portion configured to be disposed between a pair of adjacent spinous processes, the cylindrical portion having a longitudinal length at a first time and a longitudinal length at a second time when the portion of the cylindrical portion is disposed between the pair of adjacent spinous processes, the longitudinal length at the second time being different than the longitudinal length at the first time, the saddle portion configured to receive a first spinous process from the pair of adjacent spinous processes; wherein the saddle portion comprises an concave surface facing outwardly away from the cylindrical portion generally parallel to a longitudinal axis of the cylindrical portion and disposed between first and second arms of the saddle; the first arm having a first passage defined therein extending through the first arm and fully circumscribed thereby; the second arm having a second passage therein extending through the second arm and fully circumscribed thereby; the first and second passages disposed transverse to the longitudinal axis of the cylindrical portion; a tether configured to couple the implant member to the first spinous process; the cylindrical portion having a longitudinally extending spiral groove disposed along an exterior of the cylindrical portion.
