View Edit Delete	FLO-5PROV	During a procedure, when a user rotates the driver handle 560 the drive member 580 rotates the screw member 118 to expand or collapse the expandable intervertebral implant. As the driver handle 560 rotates about the longitudinal axis 460, the shoulders 526 cooperate with the tabs 528 to retain the proximal wedge 114 such that the screw member 118 rotates but the proximal wedge 114 and expandable intervertebral implant do not rotate.	87	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	FIG. 5 illustrates in the exploded view that the driver 440 is configured to fit within the longitudinal opening 530 of the inserter fork 430. When installed within the inserter fork 430, the shaft 570 is long enough that the driver handle 560 remains outside the longitudinal opening 530 and the drive member 580 sits between the protrusions 522. With the protrusions 522 seated within the recesses 524 of the proximal wedge 114 of an attached expandable intervertebral implant, the expandable intervertebral implant is securely attached to the inserter 400.	86	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The drive member 580 is configured to engage a drive recess 244 (See FIG. 2H) of a screw member 118. Accordingly, the drive member 580 is configured to have a shape and configuration that matches the type of drive recess 244 of the screw member 118. Depending on the type of recess 244, the drive member 580 has a corresponding type and shape such as a slot to fit a slotted recess 244, a torx end to fit a torx recess 244, a Philips end to fit a Philips recess 244, and the like. Of course, those of skill in the art recognize that the shape and configuration of the drive member 580 and the recess 244 can be reversed and thus comprise an embodiment within the scope of the present disclosure. The drive member 580 is configured to connect to the shaft 570 and fit within the inserter fork 430 such that the drive member 580 seats within the drive recess 244 when the expandable intervertebral implant is attached to the inserter 400.	85	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The shaft 570 can be a solid piece of material that connects the driver handle 560 and the drive member 580. The shaft 570 can have a circular cross section and is sized to fit within the longitudinal opening 530.	84	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	The driver 440 includes a driver handle 560, a shaft 570, and a drive member 580. In an exemplary embodiment, the driver handle 560 can be connected to, or coupled to, the shaft 570. The driver handle 560 enables a user of the inserter 400 to rotate the shaft 570 and drive member 580 during a surgical procedure. The driver handle 560 has a circular cross section and is sized for convenient rotation in either direction about the longitudinal axis 460.	83	Added by DJM 2 2021	2/18/21, 12:00 AM
View Edit Delete	FLO-5PROV	In certain embodiments, the inserter fork 430 can be splayed prior to assembly (for example by way of the the bias member 540) and insertion of the inserter fork 430 within the arm 414. Thus, assembling the inserter fork 430 within the arm 414 brings the prongs 520 closer together and movement of the inserter fork 430 to an extended position results in the prongs 520 moving further apart, which can release an attached expandable intervertebral implant 100.	82	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	In the illustrated exemplary embodiment, the pair of prongs 520 are configured to engage with an expandable intervertebral implant. 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
