Pectus Excavatum requires multiple procedures as a person outgrows the Nuss bar that holds up their sternum. Our project eliminates the need to take out and replace the Nuss bar. It creates a bar that grows along with the patient through a robotically extended bar. The extension method is through telescoping, where the bar is broken up into pieces that fit into each other. The success of this project would revolutionize this procedure since the new procedure would be significantly less invasive.
