View Edit Delete	FLO-5PROV	Referring now to FIG. 1C and 1D, in certain embodiments, an expandable intervertebral implant 100 can include a plurality of ridges 136a along a surface of the upper endplate 110 and a plurality of ridges 136b along a surface of the lower endplate 112. The ridges 136a along a surface of the upper endplate 110 can serve to engage a superior vertebral body and the ridges 136b along a surface of the lower endplate 112 serve to engage an inferior vertebral body. The number of ridges 136a,b and/or their positions on the upper endplate 110 and/or lower endplate 112 may vary in certain embodiments of an expandable intervertebral implant 100. In the illustrated embodiment of FIG. 1C and 1D, the ridges 136a each point towards the proximal end 120 and the ridges 136b each point towards the proximal end 130. Of course, those of skill in the art recognize that other positions, patterns, placement and spacing of ridges 136a,b may be used with the expandable intervertebral implant disclosed herein.	44	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The wedge shape of the present disclosure can be seen in FIGs 1C and 1D. A first height H1 measured from a distal end 122 of the upper endplate 110 to a distal end 132 of the lower endplate 112 is greater than a second height H2 measured from a proximal end 120 of the upper endplate 110 to a proximal end 130 of the lower endplate 112. In certain embodiments, the surface of one, or both of, the upper endplate 110 and the lower endplate 112 from the distal ends 122, 132 to the proximal ends 120, 130 can be straight. In other embodiments, such as the embodiment illustrated in FIGs 1C, 1D, the surface of one, or both of, the upper endplate 110 and the lower endplate 112 from the distal ends 122, 132 to the proximal ends 120, 130 can include a camber.	43	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	Referring now to FIG. 1C and 1D, in certain embodiments, an exemplary expandable intervertebral implant 100 is configured to form a wedge shape. The wedge shape may be observable when the expandable intervertebral implant 100 is in a collapsed configuration and is viewed in profile. Alternatively, or in addition, wedge shape may be observable when the expandable intervertebral implant 100 is in an expanded configuration and is viewed in profile. As used herein, “wedge shape” refers to a shape that resembles a wedge in which the three dimensional object, when viewed in profile has a first height measured at one end that is greater than a second height measured at an opposite end.	42	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG 1D illustrates that the second side 128 lacks the pair of fingers 134 and the tab 124. FIG 1D does illustrate an end of the pair of fingers 134 on the first side 126 that can extend beyond a top of the upper endplate 110 and an end of the tab 124 on the first side that can extend beyond a bottom of the lower endplate 112.	41	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In the illustrated embodiment, the pair of fingers 134 extends from the first side 126 of the lower endplate 112 and the second side 128 lacks the pair of fingers 134. The pair of fingers 134 cooperate with the tab 124 to keep the upper endplate 110 aligned longitudinally with the lower endplate 112. The pair of fingers 134 may be configured to slidably engage with the tab 124 of the upper endplate 110.	40	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 1C illustrates a first side 126 of the expandable intervertebral implant 100 of FIG. 1A and FIG. 1D illustrates a second side 128 of the expandable intervertebral implant 100 of FIG. 1A. Referring to FIG. 1C, the lower endplate 112 can include a proximal end 130, a distal end 132, and a pair of fingers 134. In general, the proximal end 130 of the lower endplate 112 may include substantially the same area as the proximal end 120 of the upper endplate 110 and the distal end 132 of the lower endplate 112 may include substantially the same area as the distal end 132 of the upper endplate 110.	39	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In the illustrated embodiment, the tab 124 extends from a first side 126 of the upper endplate 110 and a second side 128 lacks a tab 124. The tab 124 serves to keep the upper endplate 110 aligned longitudinally with the lower endplate 112. The tab 124 may be configured to slidably engage with the lower endplate 112.	38	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 1A is a perspective top view of the proximal end 120 of the expandable intervertebral implant 100 and FIG. 1B is a perspective top view of the distal end 122 of the expandable intervertebral implant 100 of FIG. 1A. The distal end 122 of the upper endplate 110 is an end of the upper endplate 110 that first enters the space between two vertebral bodies as a surgeon installs the expandable intervertebral implant 100. In certain embodiments, the distal end 122 of the upper endplate 110 is near an end of the expandable intervertebral implant 100 that includes the distal wedge 116.	37	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The upper endplate 110 may include a proximal end 120, a distal end 122, and a tab 124. The proximal end 120 of the upper endplate 110 is an end of the upper endplate 110 closest to a surgeon installing the expandable intervertebral implant 100 between two vertebral bodies. The proximal end 120 of the upper endplate 110 is near an end of the expandable intervertebral implant 100 that removably connects to an insertion tool used to install the expandable intervertebral implant 100. The proximal end 120 of the upper endplate 110 is near an end of the expandable intervertebral implant 100 that includes the proximal wedge 114.	36	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 1A is a perspective view depicting one exemplary embodiment of an expandable intervertebral implant 100. The expandable intervertebral implant 100 may generally include an upper endplate 110 configured to engage a superior vertebral body (not shown), a lower endplate 112 configured to engage an inferior vertebral body (not shown), a proximal wedge 114, a distal wedge 116, and a screw member 118.	35	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	Similarly, a narrower expandable intervertebral implant can enable MIS surgery techniques that use a narrower incision and/or narrower cannulas to perform the procedure. A narrower expandable intervertebral implant can facilitate positioning and placement of the implant. In certain circumstances two or more expandable intervertebral implants may be used to provide desired support for vertebral bodies.	34	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The head 238 can be configured to engage and seat within an opening in the proximal wedge 114. The threads 240 of the shank 236 can be configured to engage with one or more threads or a lip within the barrel 234 of the distal wedge 116. In one embodiment, an opening of the barrel 234 may extend through the distal wedge 116. The screw member 118 can include a drive recess 244 on one end of the head 238. The screw member 118 includes a recess 244 configured to receive a drive member, described below. The recess 244 can be configured to have any one of a variety of shapes including slotted, Torx, Torx plus, Philips, Quadrex, Pozidriv, square recess, tri-wing, spanner, or the like. The drive recess 244 can be centered on a longitudinal axis 246 of the screw member 118.	58	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	For example, in one embodiment, the expandable intervertebral implant may have a wedge shaped profile with a narrower part of the wedge on a proximal end of the expandable intervertebral implant and a wider part of the wedge on a distal end of the expandable intervertebral implant. An expandable intervertebral implant with such a wedge-shaped profile can facilitate insertion of the expandable intervertebral implant during a MIS surgical procedure. In addition to the wedge-shaped profile, certain embodiments of the expandable intervertebral implant may include a camber on a top surface and bottom surface of the expandable intervertebral implant to further facilitate placement and positioning of the expandable intervertebral implant between vertebral bodies during the MIS procedure. Of course, one skilled in the art may recognize other situations and advantages of a wedge-shaped profile for an expandable intervertebral implant; this disclosure contemplates all such situations and advantages.	33	Added by DJM 2 2021	2/18/21, 12:00 AM
