View Edit Delete	FLO-2	The size and shape of the opening 150 and the cross-sectional diameter of the screw member 400 (including the threads 410) impact how much the expandable intervertebral implant 300 expands when the screw member 400 is inserted into the opening 150. In one embodiment, the screw member 400 has a cross-sectional diameter D greater than height H of the opening 150. In this manner, as the screw member 400 is inserted in the opening, the lattice, mesh, and/or pattern of pores/openings in the upper plate 110 (or upper mesh 370), lower plate 120 (or lower mesh 380), and first lattice 130 and second lattice 140 (or first wall 350 and second wall 352) enable the opening 150 to enlarge to accept the screw member 400. In certain embodiments, the cross-sectional diameter D of the screw member 400 is greater than width W of the opening 150. In such an embodiment, insertion of the screw member 400 causes the opening 150 to widen beyond width W.	108	Added by DJM 2 2021	2/18/21, 12:00 AM

In one embodiment, rotation of the screw member 400 in direction 560 moves the screw member 400 deeper into the opening 150 and rotation of the screw member 400 in direction 570 moves the screw member 400 out of the opening 150, extracts the screw member 400. In one embodiment, activation of a driver 162 includes engaging the drive recess 502 and rotating the screw member 400 in the direction that moves the screw member 400 into the opening 150 and de-activation of the driver 162 includes engaging the drive recess 502 and rotating the screw member 400 in the direction that removes the screw member 400 from the opening 150.	109	Added by DJM 2 2021	2/18/21, 12:00 AM

View Edit Delete	FLO-2	In one embodiment, activation of the driver 162 can include rotating a screw member 400 about its longitudinal axis 414 moves the screw member 400 deeper into the opening 150 such that the driver 162 expands the first mesh 360, the second mesh 362, the upper mesh 370, and the lower mesh 380.	96	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, the expandable intervertebral implant 300 can include a first mesh 360 (of first wall 350), a second mesh 362 (of second wall 352), an upper mesh 370 and a lower mesh 380. The first mesh 360 and second mesh 362 may each have a particular pattern of pores or openings in the mesh, referred to herein as a first pattern. In addition, the opening 150 may comprise an elliptical cross-section with a predetermined height H. In such an embodiment, the first pattern and height of the elliptical cross-section of the opening 150 may be each selected such that activation of the driver 162 of the expansion mechanism 160 causes a predetermined increase in distance (Δ H = height 580’ – height 580) between the upper plate 110 and the lower plate 120.	112	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In addition, or alternatively, the upper mesh 370 and lower mesh 380 may each include a second pattern. The second pattern may be the same as the first pattern or the first pattern and the second pattern may each be different. The first pattern and the second pattern may each be selected such that activation of the driver 162 of the expansion mechanism 160 causes a first predetermined increase in a distance, such as (Δ H = height 580’ – height 580, or h1 + h2), between the upper plate 110 and the lower plate 120 that differs from a second predetermined increase in a distance, such as (Δ W = width 590’ – width 590, or w1 + w2), between the first wall 350 and the second wall 352. By using a different pattern for the upper lattice 310 and lower lattice 320 from a pattern used for the first lattice 130 and second lattice 140 an amount of expansion along a cephalad-caudal axis 520 and a medial-lateral axis 530 can each be independently managed or determined.	113	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In certain embodiments, a range of expandable intervertebral implants may be made available to a surgeon. The range of expandable intervertebral implants may include a plurality of variations among the size and/or shape of the opening 150, pattern(s) for the lattice and/or mesh of the lattices, walls, or plates, different expansion mechanisms 160, and the like. For example, different patterns for opposite sides of the expandable intervertebral implant may be used in the range of expandable intervertebral implants which each provide a different amount of expansion when installed.	114	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	If a range of implants may be used for a given procedure, the plurality of variations among the size and/or shape of the opening 150, pattern(s) for the lattice and/or mesh of the lattices, walls, or plates, different expansion mechanisms 160 may facilitate pre-operative selection of the optimal implant(s). More particularly, a suitable size, shape, ratio of collapsed height and/or width to expanded height and/or width, type of expansion mechanism 160, and/or other hardware may be pre-operatively selected. In this manner, the surgeon may choose an expandable intervertebral implant that may provide an optimal outcome for the patient.	115	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In one embodiment, that includes a single pre-operatively selected expandable intervertebral implant or an expanded configuration selected from a range of implants, the first lattice 130 and the second lattice 140 may each have a pre-selected first pattern, size of the opening 150, and/or cross-sectional diameter of the screw member 400 such that rotation of the screw member 400 about the longitudinal axis moves the screw member 400 within the opening 150 and expands the expandable intervertebral implant 100/300 along a cephalad-caudal axis 520 and along a medial-lateral axis 530 to a target expanded configuration.	116	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	Alternatively, or in addition, a single expandable intervertebral implant may be available and the expansion mechanism 160 may include a set of screw members 400. Each member of the set of screw members 400 may have a different cross-sectional diameter. In one embodiment, a surgeon may use a plurality of screw member 400 from the set of screw members 400 to expand the expandable intervertebral implant. For example, the surgeon may start with a screw member 400 having a smaller diameter, insert this screw member 400, remove the smaller diameter screw member 400, and then insert progressively larger diameter screw members 400 until an optimal level of expansion is achieved.	117	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	Figures 6A-6F illustrates different patterns that can be used in embodiments of the present disclosure. Figure 6A illustrates a pattern 600 created by a uniform spacing of geometric shapes 602. In certain embodiments, the pattern 600 may be formed from one or more other geometric shapes including polygons, and shapes formed from curves such as circles, ovals, ovoids, ellipse, or the like. In certain embodiments, the edges 604 are configured to break or fail as the expandable intervertebral implant expands. This breakage may increase structural strength of components of the expandable intervertebral implant that include these edges 604.	118	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In Figure 6A, the geometric shapes 602 are hexagons. The geometric shapes 602 are formed by edges 604 that define pores or openings 606 in the pattern 600. The pores 606 facilitate expansion of the structure having the pattern. The pores 606 may facilitate bone growth through the expandable intervertebral implant as part of a recovery process once the expandable intervertebral implant is installed in a patient.	119	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	As an expandable intervertebral implant expands the geometric shapes 602 deform and stretch. The size, shape, and distribution of the pores 606 may be predetermined such that the structure having the pattern will expand to a desired or target distance.	120	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	In the pattern 600a of Figure 6A, the geometric shapes 602 are hexagons. In the pattern 600b of Figure 6B, the geometric shapes 602 are octagons. In the pattern 600c of Figure 6C, the geometric shapes 602 are diamonds. In the pattern 600d of Figure 6D, the geometric shapes 602 are ovals. In the pattern 600e of Figure 6E, the geometric shapes 602 are triangles. In the pattern 600f of Figure 6D, the geometric shapes 602 are quadrilaterals, such as for example trapezoids.	121	Added by DJM 2 2021	2/18/21, 12:00 AM

In the illustrated embodiment, the pattern 700a includes a repeated and evenly distributed set of pentagons 706, ovals 708, and hexagons 710.	124	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-2	Figure 4B illustrates a side elevation view of the screw member 400 of Figure 4A. Figure 4B illustrates that the head 404 connects to a proximal end 406 and the tapered end 416 connects to a distal end 408. In certain embodiments, the screw member 400 has a circular cross section. As described in more details below, a cross-section of the screw member 400 has a greater diameter than one or more of a height and a width of the opening 150. The greater height causes the expandable intervertebral implant to expand as the screw member 400 enters the opening 150.	82	Added by DJM 2 2021	2/18/21, 12:00 AM
