Abstract:
1. A system for assessing an intervertebral disc space comprising: an elongated catheter with proximal and distal ends; an expandable body carried at the distal end of the elongated catheter and including a distal cap portion; a mandrel extending through the elongated catheter and the expandable body and fixedly attached to the distal cap portion such that the mandrel is configured to adjust a length of the expandable body by movement of the distal cap portion in a first direction to increase a distance between the distal end of the elongated catheter and the distal cap portion from a first distance to a second distance when the expandable body is in an uninflated state and maintain the second distance between the distal end of the elongated catheter and the distal cap portion when the expandable body is in an inflated state, wherein the mandrel is movable within the elongated catheter and the expandable body to reposition the distal cap portion relative to the distal end of the elongated catheter while the expandable body is positioned within the intervertebral disc space.
