Evaheart, Inc. (EVI) products

EVAHEART®2 LVAD hydraulically suspended open-vane impeller system provides flat PQ curve pump performance. This next generation technology supports extraordinary augmentation of Pulsatility by supporting wide-ranged flow capacity at high peak flow, benefiting end organ function and microcirculation.

The fully integrated controller is the external wearable component that controls pump speed and CSU (Cool Seal Unit) water pressure. The controller features 2 external battery slots for continuous support and an emergency battery installed as a backup power source. The controller features 2 screens: a display panel and controller screen. The display panel features LED indicators for charge indicators and a status indicator. The controller screen is a touch screen with 4 different tabs for instantaneous pump speed information, CSU parameters, battery indicators, and device settings.

The CSU (Cool Seal Unit) provides a reservoir and filter for continuous circulation of sterile water into the pump to levitate the impeller. This feature paired with the impeller’s wide flow gaps allow the device to operate at low speeds while maintaining high blood flow.

The emergency controller is a backup circuitry for the main controller. Requiring only two connections, an external battery and the blood pump cable, the blood pump automatically powers the controller at a fixed speed.
