Abstract
Intervertebral inflatable distractors employing thecal sac retractors, and related systems and methods are disclosed. Adjacent vertebrae are spaced apart or distracted to prepare for the installation of intervertebral cages during spine surgery. An intervertebral inflatable distractor may include a inflatable portion having first and second inflation modes. In the lower-volume first mode, the inflatable portion may be efficiently received within the intervertebral space, then the higher-volume second mode may be used to abut against vertebrae endplates to urge them apart and thereby provide space to receive the cages. A thecal sac retractor of the intervertebral inflatable distractor may also be used to abut against the thecal sac to provide space for larger cages. In this manner, an interbody cage may be efficiently installed between vertebrae while minimizing injury to the vertebrae and the thecal sac.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
