MarginProbe, a Device for Intraoperative Assessment of Margin Status in Breast Conservation Surgery

The study is a prospective, multi-center, randomized, double arm study demonstrating the
effectiveness of the device in adjunctive use for locating the tissue for additional
excision following primary specimen excision. One arm is a "Standard of Care" (SOC) Control
group and the other arm a "Device+SOC" group.In the "Device +SOC" group the surgeon will use
the MarginProbe device on the tissue specimen removed during the surgical procedure.The
surgeon will use the results derived from the device and other routine assessments to decide
if it is necessary to remove some additional breast tissue.
