摘要:
Systems and methods for implanting a spinal implant in a spinal column are disclosed. In one example, an illustrative system may include a delivery device including a proximal end region and a distal end region, a spinal implant releasably coupled to the distal end region of the delivery device, and a sleeve disposed about the spinal implant and at least a portion of the delivery device. In some cases, a distal portion of the sleeve may include a predetermined weakened region that may be configured to separate when a force is applied to the weakened region, which in some cases, may be applied with a pull string. In another example, a distal portion of the sleeve may be reverse folded upon itself such that the retractable sleeve rolls off of the spinal implant when the retractable sleeve is retracted.
