Arrow 248 illustrates a first direction for rotation of the screw member 118 about the axis 246 and arrow 250 illustrates a second direction for rotation of the screw member 118 about the axis 246.	65	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	By way of example, angles between the ramps 214, 222 and wedges 114, 116 can be selected such that the upper endplate 110 moves uniformly vertically relative to the lower endplate 112. In another embodiment, the the ramps 214, 222, wedges 114, 116, and/or angles between them are configured such that a ratio of the first height H1 to the second height H2 (See FIG. 1C, 1D) changes as the exemplary expandable intervertebral implant 100 transitions from a collapsed configuration to a partially expanded configuration or expanded configuration. For example, in an expanded configuration H1 and H2 can be substantially the same.	64	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In certain embodiments, the proximal wedge 114, distal wedge 116, proximal ramp 214 and/or distal ramp 222 are configured such that the upper endplate 110 move vertically uniformly relative to the lower endplate 112. Consequently, a ratio of the first height H1 to the second height H2 (See FIG. 1C, 1D) remains the substantially the same as the exemplary expandable intervertebral implant 100 transitions from a collapsed configuration to a partially expanded configuration or expanded configuration. In other words, where H1 is greater than H2 in a collapsed configuration, H1 continues to be greater than H2 in a partially expanded configuration or expanded configuration.	63	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	Conversely, movement of the proximal wedge 114 down the ramps 210, 222 causes the upper endplate 110 to move vertically relative to the lower endplate 112 and to move vertically closer to the lower endplate 112. Movement of the distal wedge 116 down the ramps 222,226 causes the upper endplate 110 to move vertically relative to the lower endplate 112 and to move vertically closer to the lower endplate 112.	62	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	Rotating the screw member 118 about the axis 246 in a first direction 248 (See FIG. 2H) draws the proximal wedge 114 up the ramps 210, 222 and the distal wedge 116 up the ramps 222, 226. Rotating the screw member 118 about the axis 246 in a second direction 250 (See FIG. 2H) drives the proximal wedge 114 down the ramps 210, 222 and the distal wedge 116 down the ramps 222, 226. Movement of the proximal wedge 114 up the ramps 210, 222 causes the upper endplate 110 to move vertically relative to the lower endplate 112 and to separate from the lower endplate 112. Movement of the distal wedge 116 up the ramps 222,226 causes the upper endplate 110 to move vertically relative to the lower endplate 112 and to separate from the lower endplate 112.	61	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 2F illustrates a first side of the expandable intervertebral implant 100 of FIG. 1A in an expanded configuration and FIG. 2G illustrates a second side of the expandable intervertebral implant 100 of FIG. 1A in an expanded configuration. FIGs. 2F and 2G illustrate that the proximal wedge 114 and distal wedge 116 are closer together than in a collapsed configuration as illustrated in FIGs. 1C and 1D. In the collapsed configuration, shown in FIGs. 1C and 1D, the proximal wedge 114 is closer to the proximal ends 120, 130 and distal wedge 116 is closer to the distal ends 122, 132. In the expanded configuration, shown in FIGs. 2F and 2G, the proximal wedge 114 is closer to the distal wedge 116 and further from the proximal ends 120, 130 and distal wedge 116 is closer to the proximal wedge 114 and further from the distal ends 122, 132.	60	Added by DJM 2 2021	2/18/21, 12:00 AM

View Edit Delete	FLO-5PROV	wherein the implant comprises a wedge shape selected such that, in the collapsed configuration, a first height measured from the distal end of the upper endplate to the distal end of the lower endplate is greater than a second height measured from the proximal end of the upper endplate to the proximal end of the lower endplate.	99	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	a screw member positioned between the upper endplate and the lower endplate, the screw member comprising a shank comprising threads that engage at least one of the proximal wedge and the distal wedge such that rotation of the screw member in a first direction about an axis of the shank draws at least one of the proximal wedge and the distal wedge toward each other to move the implant to an expanded configuration, and rotation of the screw member in a second direction about the shank separates at least one of the proximal wedge and the distal wedge from each other to move the implant toward a collapsed configuration; and	98	Added by DJM 2 2021	2/18/21, 12:00 AM

View Edit Delete	FLO-5PROV	Those of skill in the art will recognize that a variety of designs may be used for the screw member 118. For example, in one embodiment, the screw member 118 may include no head 238 and instead include threads on both ends of the shank 236. The threads on opposite ends of the shank may be traverse the shank 236 in opposite directions about the axis 246 such that rotation of the screw member 118 in one direction about the axis 246 draws the proximal wedge 114 and distal wedge 116 together and rotation of the screw member 118 in one direction about the axis 246 moves the proximal wedge 114 and distal wedge 116 away from each other.	59	Added by DJM 2 2021	2/18/21, 12:00 AM
