System, device, and method for transforaminal lumbar interbody fusion

1. A kit for installing a spine implant, the kit comprising:

an installation tool; and

a spine implant;

the spine implant comprising:

a body defining a superior surface, an inferior surface, a first end of the body, a second end of the body, a first lateral side between the first end and the second end, and a second lateral side between the first end and the second end, the body having:

a cavity extending through the body from the superior surface to the inferior surface;

a channel extending a first length along the first lateral side; a bore extending through the second end of the body and in communication with the cavity;

a first superior guide and a second superior guide in the cavity defining a superior blade guide;

a first inferior guide and a second inferior guide in the cavity defining an inferior blade guide;

a first blade situated on the superior blade guide and held in the cavity during implantation of the body but movable along the superior blade guide after implantation of the body such that a distal end of the first blade extends out of the cavity from the superior surface and beyond the body; and

a second blade situated on the inferior blade guide and held in the cavity during implantation of the body but movable along the inferior blade guide after implantation of the body such that a distal end of the second blade extends out of the cavity from the inferior surface and beyond the body; and

the installation tool comprising:

a handle;

a hollow shaft connected to the handle and having a tip with a first prong configured to be received in the channel on at least the first lateral side of the body of the implant during installation thereof;

a pusher rod configured to extend through the hollow shaft and extend the first and second blades; and

a graft rod configured to extend through the hollow shaft and introduce graft material into the spine implant.

2. The kit of claim 1 , further comprising:

first serrations on the superior surface of the body of the implant; and

second serrations on the inferior surface of the body of the implant.

3. The kit of claim 1 , wherein the distal end of the first blade of the implant has a first barb; and the distal end of the second blade of the implant has a second barb.

4. The kit of claim 1 , wherein the channel of the implant extends a second length along a second lateral side of the body, the second lateral side of the body arranged opposite the body from the first lateral side.

5. The kit of claim 4 , wherein the channel of the implant extends from the bore in the second end along the first length of the first lateral side of the body and along the second length of the second lateral side of the body.

6. The kit of claim 4 , wherein the first length and the second length extend to proximate the first end of the body of the spine implant.

7. The kit of claim 1 , wherein the hollow shaft of the installation tool has one or more openings configured to allow graft material to be inserted into the hollow shaft of the installation tool.

8. The kit of claim 1 , wherein the hollow shaft of the installation tool has a plurality of openings configured to allow graft material to be inserted into the hollow shaft of the installation tool.
