Abstract

Bellows Coils Delay effects Dogs Heart Hydraulic drives Public healthcare Solenoids Transducers
During the past few years, a number of left ventricular assist devices for diastolic augmentation have been developed which incorporate pneumatically driven pulsating pumps. The driving systems for these devices synchronize the pump to the cardiac cycle, provide any required time delay, and generate an appropriate pneumatic waveform.
