In particular, the pair of prongs 520 can each include a protrusion 522 that extends towards the longitudinal axis 460. Each protrusion 522 is configured to seat within one recess 524 of a proximal wedge 114. In addition, the prongs 520 can include shoulders 526 configured to contact tabs 528 of the proximal wedge 114 when the inserter fork 430 is connected to an expandable intervertebral implant.	80	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In one exemplary embodiment, the body 510 includes a bias member 540 positioned at one end of the body 510 and coupled to the pair of prongs 520. In one embodiment, the bias member 540 is formed as part of the body 510. In the illustrated exemplary embodiment, the bias member 540 can include two legs 542 of the body 510 formed to naturally extend out away from the longitudinal axis 460, with an opening 544 between the legs 542.	79	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The body 510 is an elongated member that can be cylindrical or can have a rectangular cross section. The body 510 includes a longitudinal opening 530 that extends from one end of the body 510 to the other. The longitudinal opening 530 is configured to receive at least part of the driver 440. The longitudinal opening 530 can have a central axis that is coaxial with the longitudinal axis 460. The body 510 can include one or more windows 512 that connect to the longitudinal opening 530. The windows 512 can facilitate cleaning and sterilizing of the inserter 400.	78	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 5 is an exploded view of an inserter fork 430, a knob 450, and a driver 440. In an exemplary embodiment, the inserter fork 430 can include a body 510, a pair of prongs 520, a longitudinal opening 530, a bias member 540, and a set of threads 550. FIG. 5 also includes a perspective view of a proximal wedge 114 and screw member 118.	77	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 4B illustrates an inserter 400 without an expandable intervertebral implant attached. FIG 4B illustrates more details of one embodiment of the inserter fork 430.	76	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The knob 450 is connected to the inserter body 410 and coupled to the inserter fork 430. In one embodiment, the inserter fork 430 is coupled to the knob 450 such that as the knob 450 is rotated about the longitudinal axis 460 in a first direction, the inserter fork 430 extends beyond a distal end of the arm 414 towards the extended position. Similarly, as the knob 450 is rotated about the longitudinal axis 460 in a second direction, the inserter fork 430 retracts within the arm 414 towards the retracted position. In one embodiment, the knob 450 can include a central opening with internal threads (not shown) that engage external threads (see FIG. 5) one an outside of the inserter fork 430.	75	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In certain embodiments, the inserter fork 430 has a length that extends beyond both ends of the arm 414. The inserter fork 430 can slidably move within the arm 414 to assume a retracted position and an extended position. In the retracted position, the inserter fork 430 engages the expandable intervertebral implant and minimally extends beyond a distal end of the arm 414. In the extended position, the inserter fork 430 disengages from the expandable intervertebral implant and extends further beyond a distal end of the arm 414 than when the inserter fork 430 is in the retracted position.	74	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The inserter fork 430 is an elongated member coupled to the knob 450 which is secured within the inserter body 410. The inserter fork 430 and knob 450 cooperate with the inserter body 410 to engage and disengage with an expandable intervertebral implant.	73	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The handle 420 is sized and configured to fit comfortably in the hand(s) of a user such as a surgeon. By holding the handle 420, a user is able to guide, position, and direct the inserter 400 attached to an expandable intervertebral implant during a procedure to install an expandable intervertebral implant, such as the expandable intervertebral implant 100.	72	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The arm 414 can include an internal longitudinal opening that is sized and configured to contain the inserter fork 430 and the driver 440. The arm 414 is a rigid member of a length that enables a user to comfortably position an attached expandable intervertebral implant during an intervertebral procedure. In certain embodiments, the arm 414 can includes one or more windows 416.	71	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The knob 450 can have a circular cross section and includes an opening that is coaxial with the longitudinal axis 460. The opening of the knob 450 can be configured to engage external threads 550 along one section of the body 510 of the inserter fork 430. As illustrated in FIG. 4, the knob 450 sits within an opening on the inserter body 410 of the inserter 400. Accordingly, rotation of the knob 450 about the longitudinal axis 460 in one direction draws the inserter fork 430 into the inserter body 410 and rotation of the knob 450 about the longitudinal axis 460 in an opposite direction extends the inserter fork 430 out of the inserter body 410.	81	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 4A illustrates one exemplary embodiment of an inserter 400 with an expandable intervertebral implant attached. In one embodiment, the expandable intervertebral implant attached to the inserter 400 can be the expandable intervertebral implant 100 illustrated in FIG. 1. The inserter 400 may generally include an inserter body 410, a handle 420, an inserter fork 430, a driver 440, and a knob 450.	69	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 3B is a top view of disassembled components of the expandable intervertebral implant 100 of FIG. 1A. Specifically, FIG. 3B illustrates the upper endplate 110 and lower endplate 112 disassembled from the expandable intervertebral implant 100. FIG. 3A also illustrates the proximal wedge 114, distal wedge 116, and screw member 118 and their positions relative to each other when the expandable intervertebral implant 100 is in an expanded configuration. FIG. 3B illustrates that the proximal wedge 114 and distal wedge 116 are closer to each other along the screw member 118 (note, in the depicted embodiment, the threads 240 are no longer visible being concealed by the barrel 234 and the distal wedge 116).	68	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 3A is a top view of disassembled components of the expandable intervertebral implant 100 of FIG. 1A. Specifically, FIG. 3A illustrates the upper endplate 110 and lower endplate 112 disassembled from the expandable intervertebral implant 100. FIG. 3A also illustrates the proximal wedge 114, distal wedge 116, and screw member 118 and their positions relative to each other when the expandable intervertebral implant 100 is in a collapsed configuration.	67	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 2J is a top view of the expandable intervertebral implant 100 of FIG. 1A in an expanded configuration and FIG. 2K is a bottom view of the expandable intervertebral implant 100 of FIG. 1A in an expanded configuration. FIGs. 2J and 2K are comparable to FIGs. 1G and 1H. In FIGs. 1G and 1H, the proximal wedge 114 and distal wedge 116 can be seen because the expandable intervertebral implant is in a collapsed configuration. In FIGs. 2J and 2K, the proximal wedge 114 and distal wedge 116 cannot be seen because the expandable intervertebral implant is in an expanded configuration. Also, FIGs 1G and 1H illustrate threads 240 of the screw member 118 because the expandable intervertebral implant is in a collapsed configuration. FIGs 2J and 2K do not illustrate threads 240 of the screw member 118 because the expandable intervertebral implant is in an expanded configuration (the threads are hidden by the barrel 234).	66	Added by DJM 2 2021	2/18/21, 12:00 AM
