An intervertebral implant configured to be fixed in an intervertebral space defined by a first vertebral body and a second vertebral body, the intervertebral implant comprising: an implant body sized to be inserted into an intervertebral space; and a fixation assembly configured to be attached to the implant body, the fixation assembly including: a housing defining a first vertebral body facing surface and a second vertebral body facing surface spaced from the first vertebral body facing surface along a transverse direction, and a proximal end and an opposed distal end that is spaced from the proximal end along a longitudinal direction angularly offset with respect to the transverse direction; at least one fixation member supported by the housing and movable from a retracted position to an extended position, whereby in the extended position the fixation member extends out from the housing and into one of the vertebral bodies(12a, 12b); and an actuator configured to iterate the fixation member from the retracted position to the extended position, characterized in that the at least one fixation member is movable from the retracted position to the extended position along a direction having a longitudinal directional component. an implant body sized to be inserted into an intervertebral space; and a fixation assembly configured to be attached to the implant body, the fixation assembly including: a housing defining a first vertebral body facing surface and a second vertebral body facing surface spaced from the first vertebral body facing surface along a transverse direction, and a proximal end and an opposed distal end that is spaced from the proximal end along a longitudinal direction angularly offset with respect to the transverse direction; at least one fixation member supported by the housing and movable from a retracted position to an extended position, whereby in the extended position the fixation member extends out from the housing and into one of the vertebral bodies(12a, 12b); and an actuator configured to iterate the fixation member from the retracted position to the extended position, characterized in that the at least one fixation member is movable from the retracted position to the extended position along a direction having a longitudinal directional component. a housing defining a first vertebral body facing surface and a second vertebral body facing surface spaced from the first vertebral body facing surface along a transverse direction, and a proximal end and an opposed distal end that is spaced from the proximal end along a longitudinal direction angularly offset with respect to the transverse direction; at least one fixation member supported by the housing and movable from a retracted position to an extended position, whereby in the extended position the fixation member extends out from the housing and into one of the vertebral bodies(12a, 12b); and an actuator configured to iterate the fixation member from the retracted position to the extended position, characterized in that the at least one fixation member is movable from the retracted position to the extended position along a direction having a longitudinal directional component.
