Abstract
Interbody fusion devices including deployable fixation members. The implant may include a spacer, optionally, an end member coupled to the spacer, and one or more fixation members configured to extend into adjacent vertebrae. The fixation members may include screws, nails, shims, tangs, spikes, staples, pins, blades, fins, or the like, and combinations thereof.
Claims16
A spinal implant comprising:
- a spacer comprising an upper surface and a lower surface, wherein the upper surface comprises one or more protrusions and the lower surface comprises one or more protrusions;
- an end member attached to the spacer, wherein the end member comprises a first opening, and a second opening;
- a first fixation member extendable through the first opening;
- a second fixation member extendable through the second opening;
- a first blocking mechanism configured to prevent backout of the first fixation member;
- and
- a second blocking mechanism configured to prevent backout of the second fixation member,
- wherein the first fixation member is non-threaded and the second fixation member is threaded, wherein the first fixation member comprises a shim having a longitudinal axis, wherein the shim comprises a head, a distal end and a spline that extends along the longitudinal axis from the head toward the distal end, wherein the shim continuously tapers from the head toward the distal end, and
- wherein the first opening is configured to receive a substantially flat portion of the first fixation member that extends laterally across a proximal end of the first fixation member.
