Abstract
An interspinous process implant is disclosed that includes a body defining a longitudinal axis, an interior cavity and opposed proximal and distal end portions, a pair of anchor wings operatively associated with the distal end portion of the body and mounted for pivotal movement relative to the longitudinal axis of the body between a first position housed within the interior cavity of the body and a second position extending radially outwardly from the body, an anchor collar operatively associated with the proximal portion of the body and mounted for axial movement relative to the longitudinal axis of the body between a first position spaced apart from the anchor wings and a second position approximated with the anchor wings, a pair of anchor blades operatively associated with the anchor collar and mounted for movement between a first position housed at least partially within the interior cavity of the body and a second position extending radially outwardly from the anchor collar.
