Abstract:
1. A method for treating a vertebral body, the method comprising: creating an access passage to an interior volume of the vertebra through a pedicle of the vertebral body, wherein creating the access passage comprises placing a cannula in contact with the pedicle; inserting an expandable structure into the interior volume of the vertebra through the access passage, the expandable structure including an interior tube having an interior lumen that passes through the expandable structure; expanding the expandable structure to compact cancellous bone and create a laterally offset cavity in the interior volume of the vertebra by delivering an inflation fluid into the expandable structure; passing fluid through the interior lumen to flush a distal region of the expandable structure and aspirate an interior of the vertebral body; and introducing a first volume of filling material into the laterally offset cavity.
