Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time.

Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.

[ We claim:] [1.]1. A method for treating bone comprising the steps ofselecting a body comprising an expandable wall,selecting a nozzle for discharging a material,inserting both the body and the nozzle through an access path in cortical bone into an interior bone volume occupied, at least in part, by cancellous bone,locating the nozzle in the interior bone volume distally of the body such that the body lays between the nozzle and the access path,causing the body to assume an expanded geometry while occupying the interior volume in the presence of the nozzle to compact cancellous bone and form a cavity in the interior volume, andconveying a material for discharge through the nozzle into the cavity distally of the body at least partially while the body occupies the interior volume.
