Claim 17:
18. A system comprising an intervertebral implant and a non-implantable device to insert the intervertebral implant into a body, the intervertebral implant comprising a top surface, a bottom surface, a central axis extending between the top surface and the bottom surface, and a side wall extending between the top surface and the bottom surface, the intervertebral implant defining an internal hollow space with at least a portion having a spherical segment shape and that is accessible through an elongate opening extending through a portion of the side wall, wherein a height of the hollow space measured in a direction of the central axis is greater than a maximum height of the elongate opening measured in the direction of the central axis, wherein the device comprises:
a drive shaft having a longitudinal axis and comprising an engagement portion with at least a portion having a spherical segment shape, wherein the drive shaft is configured to engage the hollow space of the intervertebral implant; and
a sleeve positioned around at least part of the drive shaft and movable along the longitudinal axis relative to the drive shaft;
wherein when the engagement portion of the drive shaft is in the hollow space, the spherical segment shape of the hollow space in the intervertebral implant forms an abutment against which part of an end face of the engagement portion of the drive shaft having the spherical segment shape is configured to abut, while an angular position between the intervertebral implant and the device is adjustable, and is configured to be held when a distal end of the sleeve engages the first portion of the side wall of the intervertebral implant.
