Scoop: The Atlanta-based company received $37.88 million in new funding from existing investors in June 2010. The funds went towards completing the company's CHAMPION trial of its heart failure pressure measurement system. The device is about the size of a Tylenol pill capsule. Later that year, CardioMEMS received a $60 million investment from St. Jude Medical, which could spark a potential $375 million buyout in the future.
