Dr. Rogers says that the female victim had breast implants and that they can use the model number on them to determine which surgeons in the area had implanted that model recently. However all implantable medical hardware, whether it be a artificial joint, plate, rod, screw, pin or silicone breast implant have serial numbers on them that identify the name and date-of-birth of the patient as well as the name of the surgeon that did the implantation. The main reason this is done is so that patients can be easily and quickly identified in the event of a product recall.
