Abstract
A method provides a void creation device including an expandable structure adapted to undergo expansion in the cancellous bone volume of a bone selected for treatment. The expandable structure has at least one dimension so that the expandable structure will assume a predetermined shape and size when substantially expanded that compacts only a first volume of the cancellous bone volume to form a void, leaving a second volume of the cancellous bone volume substantially uncompacted by the expandable structure. A filling material is placed within the void through the percutaneous access path.
Claims7
A method comprising
- selecting a bone for treatment having a cortical wall enclosing a cancellous bone volume,
- providing a void creation device adapted to be manipulated in the cancellous bone volume to form a void within cancellous bone, the void creation device comprising an expandable structure and a tube enclosed by and passing within the expandable structure,
- introducing the void creation device into the cancellous bone volume through a percutaneous access path along an access axis,
- deflecting the tube in the cancellous bone volume relative to the access axis after the void creation device has been introduced into the cancellous bone volume,
- expanding the expandable structure in the cancellous bone volume while the tube is deflected to create a void offset from the access axis and having a volume less than the cancellous bone volume, and
- placing a filling material within the void through the percutaneous access path,
- wherein the tube includes an interior lumen, further including providing a stylet having a preformed bend, and wherein deflecting the tube includes inserting the stylet into the interior lumen to bend the tube.
