Devices for creating voids in interior body regions and related methods

A method of creating a void in bone comprising

• establishing a percutaneous access path leading into a bone,
• introducing through the access path a first tool having a cutting tip that extends radially from the access path to contact bone,
• manipulating the cutting tip in cancellous bone to create a void in the cancellous bone,
• withdrawing the first tool,
• introducing an expandable structure through the access path, the expandable structure being adapted to undergo expansion in cancellous bone to compact cancellous bone to create a void in the cancellous bone,
• expanding the expandable structure in the cancellous bone to enlarge or further define the void,
• withdrawing the expandable structure,
• introducing through the access path a second tool having a cutting tip that extends radially from the access path to contact bone, and
• manipulating the cutting tip of the second cutting tool in the cancellous bone to enlarge or further define the void.
