Abstract
An implant system for implantation between adjacent spinous processes for the relief of pain associated with the spine. The implant has a series of spacers which may be inserted over a shaft located between adjacent spinous processes thus allowing the implant to be assembled in situ. The spacers may rotate on the shaft relative to the wings. To minimize trauma to the patient, each spacer has a tapered tissue expander to distract the opening between the spinous processes during assembly. The shaft is connected to a wing, and a second wing or deployable wing may be inserted over the shaft and locked into place.
