Claim:
1. An implantable interspinous spacer for engaging adjacent spinous processes of a subject, the implantable interspinous spacer comprising: a body defining a passageway; arms connected to the body, each arm having a pair of extensions spaced apart from one another to define an opening, wherein the arms are rotatable with respect to the body such that the arms move from an undeployed configuration for inserting the implantable interspinous spacer between the spinous processes to a first deployed configuration for positioning each spinous process within one of the openings between the extensions, and wherein the arms are linearly movable with respect to the body such that the arms move from the first deployed configuration to a second deployed configuration for distracting the spinous processes; and an actuator assembly configured to deploy the arms and comprising an actuator, wherein the actuator is movable along the passageway to rotate the arms from the undeployed configuration to the first deployed configuration and to linearly move the arms from the first deployed configuration to the second deployed configuration.
