Methods and devices for treating fractured and/or diseased bone

摘要

An expandable body is inserted into an area of cancellous within a vertebral body through a percutaneous access path. A bone filler is conveyed into the expandable body to expand the expandable body and displace cancellous bone and create a cavity occupied at least in part by the expandable body and the bone filler. The expandable body and the bone filler are left within the cavity to strengthen the vertebral body.
