Spinal repair
First Claim
1. An implant for insertion into the spinal region of a subject, comprising:
- a plurality of interlockable segments, deployable from a delivery configuration into a deployed configuration;
wherein, when the implant is in the delivery configuration, the implant comprises a linear array of the segments that are flexibly connected, and when the implant is in the deployed configuration, the segments are interlocked into a stable structure so that each segment is adjacent to and interlocked with at least two other segments.

Abstract
A spinal implant for repairing a region of a subject'"'"'s spine may have a plurality of interlockable segments that can be deployed from a delivery configuration (e.g., a linear array) into a deployed configuration. When the implant is in the delivery configuration, the implant comprises a linear array of the segments that are flexibly connected, and when the implant is in the deployed configuration, the segments are interlocked into a stable structure so that each segment is adjacent to and interlocked with at least two other segments. in the deployed configuration, the implants may have a greater strength (e.g., crush strength) and may help maintain the stability of the body region. The implant may be inserted into the spinal region by an applicator from the posterior region of the subject in the delivery configuration and assembled within the body to form the deployed configuration.
