Disclosed herein are devices for use through a cannula to create cavities within interior body regions. When deployed, the distal end of several such devices extend beyond the distal end of the catheter and can then be selectively curved into a shaped compression surface that, when articulated, creates a void within the interior body. This compression surface may then be withdrawn back into the cannula for removal and to make way for bone cement that, in certain instances, may be introduced through the same cannula. |
