Abstract
Some embodiments of the invention include a cannulated bone screw including a screw shaft with screw thread, a proximal end, a distal end, and a channel extending through the screw shaft. Some embodiments include an inlet port coupled to the channel and extending through the distal end, and an outlet port coupled to the channel by a curved or angled channel region. In some embodiments, the outlet port extends through the screw shaft and exits a side that is substantially parallel to the shaft longitudinal axis. In some embodiments, the cannulated bone screw can form part of a therapy delivery device. In some embodiments, the outlet port extends through a portion of the screw shaft and exits at the distal end. In some embodiments, the valve includes a plunger with a plunger rod within the screw shaft, and a valve seat for control of fluid flow out of the screw.
