We will provide information after the April meeting as is appropriate in cooperation with the FDA in order to reactivate the currently stalled development plan for RIGScan CR49", concluded Bupp. ABOUT NEOPROBE Neoprobe develops and provides innovative surgical and diagnostic products that enhance patient care by meeting the critical decision making needs of healthcare professionals.
