The Evaheart Pump

 The Evaheart pump is no larger than a small fist. The impeller equipped with swept-back vanes (40mm diameter) uses centrifugal force to circulate the blood. A cable links the pump to an external controller that operates the system.

Live a normal life now possible with next generation heart assist system. Many heart patients in the World are reported to be waiting for a heart transplant, and until they receive it they are attached to an artificial heart-assist system. These types of systems are being steadily improved in World, and a next-generation advance, the Evaheart, is a heart assist system developed in Japan by a project headed by Dr. Yamazaki Kenji. He is a professor at Tokyo Women's Medical University, and director of the Department of Surgery there. The main components of the Evaheart system are: a pump attached to the left ventricle of the poorly functioning heart to send blood through the main artery; external compact batteries and a controller to operate the system.

Patients using other heart assist system may experience problems such as an erratic pump that forces them to remain in the hospital for a long time. The Evaheart avoids this with two distinctive features: its pump is highly reliable and durable thanks to a rotating impeller with swept-back vanes; and it is made with precision technology that helps prevent blood vessels from becoming blocked. So patients do not have to be hospitalized for a long time, and can go about their lives as they normally would.
