EVAHEART MEDICAL USA, INC. (EMUSA) was established in October, 2002 in Pittsburgh, PA as a wholly owned subsidiary of SUN MEDICAL TECHNOLOGY RESEARCH CORPORATION (Sun Medical) in order to prepare for clinical trials in the United States for Sun Medical’s EVAHEART LVAS (Left Ventricular Assist System). Once the device is approved by the FDA, the company will function as a distributor and provide customer support for the EVAHEART LVAS in the US.

Sun Medical was established in 1991 in Suwa City, Nagano, Japan to develop the EVAHEART LVAS under the license of Dr. Kenji Yamazaki of Tokyo Women’s Medical University. The company, along with Dr. Yamazaki, collaborated with the University of Pittsburgh on a series of animal experiments to verify system performance and design improvements. Because of its relationship with the University, it was natural for the company to establish in Pittsburgh.

In August 2008, Sun Medical completed its EVAHEART LVAS clinical trial in Japan.
