Abstract
An inflatable bone tamp for performing a minimally invasive surgical procedure includes an outer shaft defining an internal lumen, an inflatable structure coupled to the outer shaft, and an inner shaft movably disposed within the internal lumen and coupled to a distal end region of the inflatable structure. The internal lumen is sized to receive the inflatable structure, such that by moving the inner shaft relative to the outer shaft, the inflatable structure can be retracted into the internal lumen (and likewise can be extended from within the internal lumen for deployment in bone). This retraction capability can beneficially protect the inflatable structure during positioning/removal, and can also enhance recovery from radial tears of the inflatable structure.
