A steerable expandable spinal implant comprises a body and a movable endplate. The implant including an actuatable expansion mechanism coupled to the body, the expansion mechanism comprising a rotatable drive gear and a follower spindle coupled by a transmission belt. The drive gear is rotatable in a first direction to rotate the body about an axis adjacent a body proximal end, and in a second opposite direction to actuate the expansion mechanism to move the endplate away from the body and expand the spinal implant. A brake shoe is rotatably supported by the body adjacent the proximal end, the brake shoe being operable in a first mode to allow the body to rotate about the axis, and in the second mode to constrain movement of the body relative to brake shoe thereby allowing actuation of the expansion mechanism to move the endplate away from the body and expand the implant.

Steerable and expandable interbody fusion device and associated instrumentation

An expandable spinal implant comprises a body having a hollow interior, a proximal end and a distal end, the body supporting an endplate movable relative to the body in a first direction away from said body. An actuatable expansion mechanism, supported within the hollow interior is coupled to the body and the movable endplate to move the movable endplate relative to the body. The expansion mechanism comprises a rotatable drive gear and a rotatable follower supported spaced from the drive gear, and a transmission belt rotatively coupling the drive gear and the follower to transfer rotative motion from the drive gear to the follower upon actuation of the expansion mechanism. The transmission belt is formed in a continuous loop extending in an oblong shape around the drive gear and the follower and has an inward curve on one side of the loop between said drive gear and the follower.
