Abstract:
1. A system for performing a surgical procedure, the device comprising: a cannula comprising a sidewall, the sidewall defining an open proximal end, an open distal end, and an inner lumen between the open proximal end and the open distal end, wherein the sidewall further defines a partial circumferential opening between the open proximal end and the open distal end; a material delivery nozzle sized to fit at least partially through the cannula; and an expandable bone tamp defining a longitudinal axis and comprising an elongate shaft carrying an expandable structure and an elongate distal tip defining a length along the longitudinal axis, the expandable structure defining a length along the longitudinal axis, wherein the length of the elongate distal tip is at least half of the length of the expandable structure, wherein the expandable structure is sized to fit through the inner lumen when in an unexpanded state, wherein the elongate shaft is sized to deliver the expandable structure from the open proximal end, through the inner lumen, and out the open distal end, and wherein the material delivery nozzle comprises a closed distal tip and at least one sidewall opening to allow passage of bone filler material out from within the material delivery nozzle.
