Abstract
A device for delivery of a spinal rod to a bone anchor includes an inner tube and an outer tube disposed about at least a portion of the inner tube. The inner tube is adjustable relative to the outer tube along the longitudinal axis of the outer tube between a first position and a second position in which the distal end of the inner tube contacts the bone anchor. A spring is interposed between the inner tube and the outer tube to bias the inner tube distally. A locking member is coupled to the outer tube and is adjustable between a proximal position in which the locking member is spaced apart from the inner tube and a distal position in which the locking member inhibits proximal axial motion of the inner tube relative to the outer tube.
