发明名称 Spinal grooved director with built in balloon
摘要 The present invention is directed toward a grooved director with a built in balloon which is inflated by a pump to a predetermined pressure to expand the walls of a collapsed vertebra. The device is inserted into the body of the compressed vertebra and the grooved director is positioned and aimed in a direction under the compressed superior end plate of the vertebral body. The balloon inside of the grooved director is inflated and the force and direction of balloon inflation restores the height of the fractured vertebrae. The balloon is deflated and the grooved director is circumferentially rotated while intermittently inflating and deflating the balloon to creates a symmetrical space within the center of the vertebral body. The balloon is deflated and the grooved director device with balloon is removed leaving a rebuilt vertebra which may be filled with a biocompatible material.
