1. A method of creating a void in bone comprisingestablishing a percutaneous access path leading into a bone,introducing through the access path a 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 tool,introducing a first 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 first expandable structure in the cancellous bone to enlarge or further define the void,withdrawing the first expandable structure, introducing a second expandable structure through the access path, andexpanding the second expandable structure in the cancellous bone to enlarge or further define the void.

Abstract
Several embodiments of cutting tips for tools for creating voids in interior body regions are provided. The cutting tips provide for rotational and translational cutting. An actuator mechanism for deploying a cutting tip converts the rotational movement of a wheel into translational movement of a plunger rod. The actuator mechanism provides positive cutting action as the cutting tip is moved from a first, non-deployed position to a second, deployed position and from the second, deployed position to the first, non-deployed position. Methods of creating a void in bone provide one or more mechanical cutting tools that may be used in combination with one or more expandable void-creating structures to form a void of a desired size and configuration.

1. A method of creating a void in bone comprising
establishing a percutaneous access path leading into a bone, introducing through the access path a 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 tool, introducing a first 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 first expandable structure in the cancellous bone to enlarge or further define the void, withdrawing the first expandable structure, introducing a second expandable structure through the access path, and expanding the second expandable structure in the cancellous bone to enlarge or further define the void.

8. 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.

14. 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 of the first tool in cancellous bone to create a void in the cancellous bone, withdrawing the first tool, introducing through the access path a second tool having a cutting tip that extends radially from the access path to contact bone, manipulating the cutting tip of the second tool in the cancellous bone to enlarge or further define the void, withdrawing the second 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, and expanding the expandable structure in the cancellous bone to enlarge or further define the void.

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

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

34. A method of creating a void in bone comprising
establishing a percutaneous access path leading into a bone, 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, 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 the cancellous bone to enlarge or further define the void, withdrawing the first tool, 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 tool in the cancellous bone to enlarge or further define the void.
