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.
Claims20
A device for performing a surgical procedure, the device comprising:
- an elongate shaft defining an interior lumen;
- an inflatable structure coupled to the elongate shaft;
- and
- an inner shaft at least partially disposed within the interior lumen, wherein the inner shaft is movable with respect to the elongate shaft to retract the inflatable structure into the interior lumen.
A system for performing a surgical procedure, the system comprising:
- a cannula defining an access lumen;
- and
- an inflatable bone tamp, the inflatable bone tamp comprising an elongate shaft defining an interior lumen, an inflatable structure coupled to the elongate shaft, and an inner shaft at least partially disposed within the interior lumen,
- wherein the inner shaft is movable with respect to the elongate shaft to retract the inflatable structure into the interior lumen, and
- wherein the elongate shaft is sized to fit through the access lumen.
A method comprising:
- establishing an access path to a bone;
- driving an inflatable structure through the access path using an elongate shaft;
- inflating the inflatable structure to manipulate the bone;
- deflating the inflatable structure;
- retracting the inflatable structure into the elongate shaft;
- and
- withdrawing the elongate shaft from the access path.
