ABSTRACT:
An implantable distractor that provides controlled forceful movement either to facing bone ends created by osteotomy or across cranial sutures for the purpose of fostering bone deposition to support bone growth (distraction osteogenesis). The improved Distractor adjusts separation of such through precise, forceful, incremental movements. The mechanism has an actuator powered by intermittent electrical current flow through a shape-memory-effect (SME) actuation component. The SME component deforms forcefully. This force is amplified to result in incremental separation of two plates affixed to bone on either side of the osteotomy or suture.
