1. An expandable interbody device for placement between adjacent vertebrae comprising:
- an upper structure comprising an upper proximal angled surface and an upper distal angled surface;
a lower structure comprising a lower proximal angled surface and a lower distal angled surface, the lower structure configured to slideably couple with the upper structure; and
a screw mechanism between the upper structure and the lower structure, the screw mechanism comprising;
a proximal section comprising a proximal frustoconical surface;
a distal section comprising a distal frustoconical surface; and
a coupler comprising a proximal side configured to engage the proximal section and a distal side configured to engage the distal section;
wherein the proximal section and the distal section are configured to rotate as a unit to change a length of the screw mechanism from a first length to a second length;
wherein the proximal frustoconical surface is configured to engage the upper proximal angled surface and the lower proximal angled surface, and the distal frustoconical surface is configured to engage the upper distal angled surface and the lower distal angled surface to move the upper structure and the lower structure from a first distance to a second distance.

Abstract
An expandable interbody device for placement between adjacent vertebrae having an upper structure, a lower structure and a screw mechanism, wherein actuation of the screw mechanism moves the upper and lower structures between a collapsed configuration and an expanded configuration. A deployment tool couples to the expandable interbody device for positioning the device between adjacent vertebrae, actuating the screw mechanism and delivering a material to a chamber of the expandable interbody device.

12. An expandable interbody device for placement between adjacent vertebrae comprising:
-
an upper structure; a lower structure configured to slideably couple with the upper structure; and a screw mechanism between the upper structure and the lower structure, the screw mechanism comprising a proximal section and a distal section that are configured to rotate as a unit to change a length of the screw mechanism from a first length to a second length; wherein the change in the length of the screw mechanism causes the distance between the upper structure and the lower structure to change from a first distance to a second distance to form a chamber to be filled by one or more of fluids, medication, bone graft material, allograft and Demineralized Bone Matrix.

13. A kit for performing spinal stabilization, the kit comprising:
-
an expandable interbody device for placement between adjacent vertebrae, wherein in an expanded configuration the expandable interbody device comprises a chamber; and a deployment tool for delivering the expandable interbody device between adjacent vertebrae, the deployment tool comprising a distal portion that is releasably attachable to the expandable interbody device and a proximal portion configured to extend outside a surgical incision; wherein the proximal portion comprises an opening to a channel that extends through the deployment tool and is in fluid communication with the distal portion of the deployment tool, the channel capable of transporting a material from outside the incision into the chamber of the expandable interbody device. - View Dependent Claims (14, 15, 16)

17. A method of implanting an expandable interbody device between adjacent vertebrae comprising:
-
positioning the expandable interbody device between adjacent vertebrae, wherein the expandable interbody device comprises; an upper structure; a lower structure configured to slideably couple with the upper structure; and a screw mechanism between the upper structure and the lower structure; rotating the screw mechanism to change a length of the screw mechanism from a first length to a second length which causes the distance between the upper structure and the lower structure to change from a first distance to a second distance to form a chamber; and injecting material into the chamber. - View Dependent Claims (18, 19, 20, 21, 22)
