Magnetic Mini-Mover Procedure to Treat Pectus Excavatum

This is a medical research study. The study investigators have developed a method to gradually repair pectus excavatum (sunken chest) deformity by placing a magnet on the sternum (breastbone) and then applying an external magnetic force that will pull the sternum outward gradually. Potential candidates for this study are children and adolescents with a previously diagnosed congenital pectus excavatum (sunken chest) deformity who are otherwise healthy and are seeking corrective surgery for their condition. They will be residents of the U.S. and between the ages of 8 and 14 years of age. Potential candidates and their families will have already been counseled about this condition and about the standard way to repair this deformity. The purpose of this study is to test what effects, good and/or bad, placing an external/internal magnetic device has on correcting pectus excavatum deformity in children, and the safety of using such a device for treatment.
