View Edit Delete	FLO-2	The lower plate 120 may include a first lower side 122 and a second lower side 124 (See Figure 1B). In one embodiment, the first lower side 122 is at, or near, a longitudinal edge of the lower plate 120 and the second lower side 124 is at, or near, an opposite longitudinal edge of the lower plate 120.	53	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	The first lattice 130 can form one wall of the expandable intervertebral implant 100. As used herein, a “lattice” refers to a three-dimensional planar structure having a plurality of pores distributed within a longitudinal plane of the structure. Furthermore, the pores of the lattice are configured to expand and/or compress in response to a tensile force or compressive force applied in opposite directions and at opposite ends of the lattice. In particular embodiments, structures of the lattice that interconnect the pores are configured and made of a material that is elastic such that lattice expands its overall shape in response to tensile force(s) and or contracts its overall shape in response to compressive force(s). In certain embodiments, a tensile force on the lattice in opposite directions and at opposite ends causes the lattice to deform, or stretch, to have a greater surface area.	54	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, the pores of the lattice comprise at least one shape. For example, in one embodiment, each of the pores can have a geometric shape, a polygon shape, a circular shape, an ovoid shape, an elliptical shape, and the like. In certain embodiments, a “lattice” may comprise a “mesh.” As used herein, a “mesh” refers to a three-dimensional planar structure having a plurality of openings distributed within a longitudinal plane of the structure. Each of the plurality of openings of the mesh may be of a common shape. Alternatively, or in addition, the plurality of openings of a mesh may include openings having two or more geometric shapes.	55	Added by DJM 2 2021	2/18/21, 12:00 AM

View Edit Delete	FLO-2	Figure 1B illustrates that the second lattice 140 provides structural support and definition to the expandable intervertebral implant 100 and connects the second upper side 114 of the upper plate 110 to the second lower side 124 of the lower plate 120.	57	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	The expandable intervertebral implant 100 can include an opening 150. As used herein, an “opening” refers to a gap, a hole, an aperture, a void in a structure, or the like. In certain embodiments, an opening can refer to a structure configured specifically for receiving something and/or for allowing access. In one embodiment, the opening 150 extends from the proximal end 170 to the distal end 180 of the expandable intervertebral implant 100. The opening 150 can include a longitudinal axis 152 that extends from one end of the opening 150 to the other. The opening 150 is between the upper plate 110, the lower plate 120, the first lattice 130, and the second lattice 140. In certain embodiments, the longitudinal axis 152 can run through a geometric center of a cross-section of the opening 150.	58	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, the opening 150 is configured and/or sized to receive an expansion mechanism 160 and/or a component of an expansion mechanism 160 (See Fig. 5A). As will be appreciated by those of skill in the art, in this disclosure, the opening 150 can receive a variety of different types of expansion mechanisms 160. In the illustrated embodiment, the opening 150 includes internal threads 154 about the longitudinal axis 152. The internal threads 154 can be configured and arranged to engage with threads of an expansion mechanism 160. One exemplary expansion mechanism 160 is described in more detail in relation to subsequent Figures. Other suitable examples of an expansion mechanism 160 include, but are not limited to a peg, a wedge, a pin, or the like. Those of skill in the art may recognize other suitable expansion mechanisms 160 that can be used in connection with the opening 150.	59	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, the expansion mechanism 160 can include a driver 162 (See Figure 5A). A driver 162 is a component of the expansion mechanism 160 configured to expand or contract the expansion mechanism 160 when the driver 162 is activated or de-activated. In one embodiment, the driver 162 is configured to expand the upper plate 110 and the lower plate 120 away from each other along a cephalad-caudal axis (See Figure 5A) by deforming the first lattice 130 and the second lattice 140. Further description of the driver is provided in relation to Figures 4A,5A.	60	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	FIG. 1A is a perspective top view from the proximal end 170 of the expandable intervertebral implant 100 and FIG. 1B is a perspective top view from the distal end 180 of the expandable intervertebral implant 100 of FIG. 1A. The distal end 180 of the expandable intervertebral implant 100 is an end that first enters the space between two vertebral bodies as a surgeon installs the expandable intervertebral implant 100. The proximal end 170 of the expandable intervertebral implant 100 is an end of the expandable intervertebral implant 100 closest to a surgeon installing the expandable intervertebral implant 100 between two vertebral bodies. The proximal end 170 is near an end of the expandable intervertebral implant 100 that includes a removably connects to an insertion tool used to install the expandable intervertebral implant 100.	61	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, the expandable intervertebral implant 100 and its components can be made from the same material. Alternatively, or in addition, the upper plate 110, lower plate 120, first lattice 130, and second lattice 140 can be made from different materials. For example, the first lattice 130 and second lattice 140 can be made from a material having a different plasticity than the upper plate 110 and/or lower plate 120. In one embodiment, the first lattice 130 and second lattice 140 can be made from a material having a common plasticity such that first lattice 130 and second lattice 140 deform together under and expansion force created by the expansion mechanism 160.	62	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	The expandable intervertebral implant 100 and/or its constituent components may be formed of any biocompatible materials, including but not limited to biocompatible metals such as Titanium, Titanium alloys, stainless steel alloys, cobalt-chromium steel alloys, nickel-titanium alloys, shape memory alloys such as Nitinol, biocompatible ceramics, and biocompatible polymers such as Polyether ether ketone (PEEK) or a polylactide polymer (e.g. PLLA) and/or others. In one embodiment, the first lattice 130 and/or the second lattice 140 can be made of metal. In some embodiments, components of the expandable intervertebral implant 100 may be formed of a less rigid material so that the upper plate 110 and/or lower plate 120 can spread apart from each other in response to the expansion mechanism 160.	63	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	The expandable intervertebral implant 100 and/or its constituent components may be manufactured using any known manufacturing method, including casting, forging, milling, additive manufacturing, and/or the like. As used herein, “additive manufacturing” refers to a manufacturing process in which materials are joined together in a process that repeatedly builds one layer on top of another to generate a three-dimensional structure or object. Additive manufacturing may also be referred to using different terms including: additive processes, additive fabrication, additive techniques, additive layer manufacturing, layer manufacturing, freeform fabrication, ASTM F2792 (American Society for Testing and Materials), and 3D printing. Additive manufacturing can build the three-dimensional structure or object using computer-controlled equipment that applies successive layers of the material(s) based on a three-dimensional model that may be defined using Computer Aided Design (CAD) software. Additive manufacturing can use a variety of materials including polymers, thermoplastics, metals, ceramics, biochemicals, and the like. Additive manufacturing may provide unique benefits, as the expandable intervertebral implant 100 together with the pores of the lattices 130/140 can be directly manufactured (without the need to generate molds, tool paths, perform any milling, and/or other manufacturing steps).	64	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	Figure 2A is a perspective top view of a proximal end of an expandable intervertebral implant 200, according to one embodiment of the present disclosure. In the illustrated embodiment, like parts are identified by common numbers in other figures. The embodiment of Figure 2A includes an upper plate 110, a lower plate 120, a first lattice 130, a second lattice 140, an opening 150, and an expansion mechanism 160 as described in relation to Figures 1A and 1B.	65	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In addition, Figures 2A and 2B illustrate details of the first lattice 130 and the second lattice 140. Specifically, the first lattice 130 and the second lattice 140 each have a pattern. As used herein, “pattern” refers to a repeated set of shape, shapes, or design within or upon a planar structure. In certain embodiments, the pattern defines the number, size, position, layout, and distribution of shapes of the lattice. The shapes of the pattern for the lattice can include the openings and/or pores of the lattice. In one embodiment, the pattern includes a distributed set of pores, or shapes, or openings, that include one or more geometric shapes of a set of geometric shapes. In certain embodiments, the set of pores of the opening is uniformly distributed. In other embodiments, the set of pores of the opening is non-uniformly distributed.	66	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In one embodiment, the pattern for the first lattice 130 can be different from the pattern for the second lattice 140. In another embodiment, the first lattice 130 and second lattice 140 both have a common pattern. In the illustrated exemplary embodiment, the first lattice 130 and the second lattice 140 each include a pattern of pores/openings shaped as hexagons.	67	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	Certain embodiments, of the expandable intervertebral implant may further include a proximal end, a distal end, and an inserter attachment feature connected to the upper plate, the lower plate, the first lattice, and the second lattice at the proximal end. The upper lattice, the lower lattice, the first lattice, and the second lattice each extend to include the inserter attachment feature. In other words, a pattern for one or more of the upper lattice, the lower lattice, the first lattice, and the second lattice may also be formed within one or more walls of the inserter attachment feature.	18	Added by DJM 2 2021	2/18/21, 12:00 AM
