Abstract:
1. An interspinous implant system for distracting and fusing at least one pair of adjacent spinous processes, said system comprising: a device including: a main body including a shaft having a longitudinal axis; first and second bases connected to said main body; first and second arms rigidly and fixedly connected to said first and second bases, respectively and extending from said bases, transverse to said longitudinal axis, wherein at least one of said first and second bases is slidably mounted on said shaft; said arms being integrally formed and rigid, with no moving parts, and configured and dimensioned to extend laterally from both lateral sides of the spinous processes when implanted therebetween and to be inserted between the spinous processes laterally from a single side thereof; said first arm having a first curvature along a top side of said first arm, said first curvature facing in a first direction parallel to said longitudinal axis of said main body, and a bottom side of said first arm opposite said first side extending straight and substantially perpendicular to said longitudinal axis; said second arm having a second curvature along a bottom side of said second arm, said second curvature facing in a second direction opposite to said first direction and parallel to said longitudinal axis of said main body, and a top side of said second arm opposite said bottom side extending straight and substantially perpendicular to said longitudinal axis; said arms being variably positionable between a closed configuration, in which said arms are positioned so that said bottom side of said first arm contacts and closes against said top side of said second arm, to facilitate insertion of said arms between the adjacent spinous processes from one side of the spinous processes, and an open configuration, in which said arms are separated from one another.
