The Prevena™ IMS is intended to manage the environment of closed surgically incision and surrounding intact skin for patients with an increased risk for developing post-operative complications such as infection.The purpose of this study is to compare the use of Prevena™ Incision Management System (IMS) versus standard wound care for the incision in subjects undergoing a sternal midline incision (sternotomy). The subjects targetted for the study are at high risk for surgical complications (like infections) around the environment of the incision.
