Abstract
Systems, devices and methods relating to a spinal implant for placement in a disc space of a spine are described. A spinal implant (1) can include a plurality of wedge members including a leading wedge (22), a trailing wedge (28), and one or more intermediary wedges (26) therebetween. The spinal implant (1) can be configured to have a first linear configuration in which the plurality of wedge members are in a linearly expanded form and a second circular configuration in which the plurality of wedge members are positioned circumferentially relative to a center axis. In its first configuration, the spinal implant (1) can be delivered to a disc space, whereby it can assume its second configuration within the disc space, thereby forming a replacement nucleus. The spinal implant (1) can be kept in its first configuration by a rod member (41) received as through the plurality of wedge members. The wedge members can be slidably removed off of the rod member (41) and can assume the second configuration.
