December 12, 2011 - CardioMEMS announced that the U.S. Food and Drug Administration's (FDA) Circulatory Systems Devices advisory panel voted against the Champion heart failure monitoring system. It is the first wireless, permanently implantable device that allows cardiologists to monitor heart failure (HF) patients from their homes. While the panel agreed with a 9-1 vote that the CardioMEMS technology is safe, the majority did not vote positively that the system is effective and that reasonable assurance of the risks associated with the device outweigh the potential clinical benefits of the technology.
