Abstract:
A device for insertion into a vertebral body to apply a force capable of compacting cancellous bone and moving fractured cortical bone, the device including a catheter extending along an axis and having a distal end sized and configured for insertion through a cannula into the vertebral body, the catheter carrying near its distal end an inflatable body having a wall sized and configured for passage within the cannula into the vertebral body when the inflatable body is in a collapsed condition, the wall being further sized and configured to apply the force in response to expansion of the inflatable body within the vertebral body, the wall including opposed side surfaces extending along an elongated longitudinal axis that is substantially aligned with the axis of the catheter, the wall including changes in wall thickness which restrain the opposed side surfaces from expanding beyond a substantially flat condition along the elongated longitudinal axis.
