1. An apparatus, comprising:
- a guide shaft;
an expansion member coupled to the guide shaft, the expansion member being configured to impart a force from within an interior of an implant to deform the implant; and
an actuator coupled to the expansion member, the actuator configured to move the expansion member from a first position to a second position.

Abstract
An apparatus includes a guide shaft, an expansion member coupled to the guide shaft, and an actuator. The expansion member is configured to impart a force from within an interior of an implant to deform the implant. The actuator is coupled to the expansion member, the actuator is configured to move the expansion member from a first position to a second position.

17. An apparatus, comprising:
-
an expansion device movable between a first configuration and a second configuration, the expansion device in the second configuration configured to deform the spinal implant;
a guide shaft configured to be inserted in a spinal implant when the expansion device is in the first configuration; and
an actuator rotatably coupled with respect to the guide shaft and configured to move the expansion device between the first configuration and the second configuration. - View Dependent Claims (18, 19)

20. A method, comprising:
-
moving an expansion device from a first configuration to a second configuration while disposed within a spinal implant, the expansion device in the second configuration configured to deform the spinal implant; and
moving the expansion device from the second configuration to the first configuration after the moving from the first configuration, the expansion device in the first configuration being substantially disengaged from the spinal implant, the spinal implant remaining deformed after the moving from the first configuration and after the moving from the second configuration. - View Dependent Claims (21)
