Methods and apparatus for deploying spinous process constraints

摘要

A surgical tool for deploying an implant includes an elongate outer shaft having a proximal end, a distal end and a central channel therebetween. An elongate inner shaft is at least partially slidably received in the central channel and an actuator mechanism is operatively coupled with either the outer or inner shaft. The tool also includes a piercing element that is coupled with the outer shaft and releasably coupled with the implant.
