Evaluation of SOMAVAC 100 Sustained Vacuum System

Participants will undergo a screening that includes medical history review. Once screening is complete, participants will undergo immediate breast reconstruction per the surgeon's typical protocol. Surgeon will place up to two (2) drain(s) per breast as customary without changing their technique at the end of the surgical procedure. SOMAVAC® 100 Sustained Vacuum System will be attached to the end of the drain(s) on one side of the subject and standard of care manual suction bulbs attached to the other side. Subjects will return to the clinic every 72 hours for visits for the first 1 to 2 weeks, until the drain drops below 25mL, or as instructed by the physician. Each visit will take about 30 minutes. Subjects will have routine phone calls with the clinic to provide their drain output information to help determine when the drains should be removed. This is a study where the standard techniques of closed suction drainage are used for the removal of fluid from a surgical site. Hence, an increased risk related to post-operative care is not anticipated.
