Spinal implant and delivery system
A spinal implant and a delivery system for spinal surgery. The delivery device may be configured to deliver, articulate, and deploy the spinal implant in a disc space between a pair of vertebrae, and to deliver or inject a bone void filler to the spinal implant for deployment of the expandable mesh component. A mesh component may provide a reservoir for larger volumes of bone void filler and greater surface area for load distribution of the spinal cage. The mesh component may include pores through which bone void filler may interdigitate against the vertebral endplates. The delivery device may include a handle having components operable to attach the spinal implant for insertion, position and orient the spinal implant in a desired location and orientation and detach the spinal implant in place. A syringe, syringe gun, and/or packing rod may be utilized to deliver bone void filler through the delivery device.
1. A spinal implant and delivery system, comprising:
a delivery device, the delivery device including:
a handle;
an outer tubular member extending from the handle;
wherein a distal end of the outer tubular member comprises a plurality of first teeth;
an inner tubular member extending through the outer tubular member;
wherein a distal end of the inner tubular member comprises a threaded connector;
a spinal implant device, the spinal implant device being removably attachable to the delivery device and including:
a housing including an inner cavity and a side opening;
a mesh portion positioned within the inner cavity of the housing;
a threaded opening for releasably engaging with the threaded connector of the delivery device;
wherein the mesh portion is adjustable between a compressed configuration and an expanded configuration;
wherein, in the expanded configuration, the mesh portion expands out of the side opening; and,
wherein the delivery device is configured to inject or introduce a bone void filler to the spinal implant device.
2. The system of claim 1 , wherein, when the spinal implant device is attached to the delivery device, the spinal implant device is adjustable between a locked configuration in which the spinal implant device is not angularly adjustable and an unlocked configuration in which the spinal implant device is angularly adjustable.
3. The system of claim 1 , wherein the spinal implant device is adjustable between a plurality of angular orientations with respect to the delivery device.
4. The system of claim 1 , wherein the bone void filler is deliverable to the spinal implant device through a lumen of the inner tubular member.
5. The system of claim 1 , wherein a distal end of the outer tubular member includes a locking mechanism operable to lock or unlock an angular orientation of the spinal implant device with respect to the delivery device.
6. The system of claim 1 , further comprising an injector for injecting the bone void filler through the delivery device and into the mesh portion of the spinal implant device.
7. The system of claim 6 , wherein the injector is comprised of a syringe, a syringe gun, and/or a packing rod.
8. The system of claim 1 , wherein the mesh portion is configured to expand into the expanded configuration upon introduction of the bone void filler.
