12. An implantable device:
-
a rod comprising opposing protuberances arranged along a longitudinal axis of the rod; a wing comprising an opening and ratcheting members on an interior wall of the opening, wherein the rod is disposed through the opening such that the ratcheting members engage the protuberances to secure the wing on the rod at a first position and disengage with the protuberances at a second position. - View Dependent Claims (13, 14, 15)

16. A method for positioning an implantable device comprising the steps on distracting adjacent spinous processes from one another creating a interspinous space between the adjacent spinous processes;
-
attaching a spinous process fusion device to a insertion instrument, the spinous process fusion device comprising, a rod having protuberances arranged along a longitudinal axis of the rod, and a first wing coupled to a first portion of the rod; positioning the spinous process fusion device in the interspinous space; actuating the rod to be in a first position; attaching a second wing to wing insertion instrument, the second wing having an opening, and ratchet members configured to couple to a second portion of the rod; placing the rod through the opening of the second wing thereby engaging the ratchet members with the protuberances on the longitudinal axis of the rod; applying pressure upon the second wing to attach the second wing to the spinous process by engaging teeth provided on the second wing with the spinous process; and removing the wing insertion instrument, and the insertion instrument. - View Dependent Claims (17, 18, 19, 20)
