Abstract:

A system for performing a procedure on a spine of a patient includes a curved tissue distractor, a curved housing, and an exterior channel. The curved tissue distractor includes a first distractor ramp and a second distractor ramp. The curved housing is configured to slide between the first and second distractor ramps. The curved housing includes a distal end, a proximal end, and an interior channel disposed between the distal end and the proximate end. The exterior channel is disposed on an outside surface of the curved housing and between the distal end and the proximal end. The curved housing is configured to slide between the first and second distractor ramps to provide access through the interior channel to the spine.
