title: An electrohydraulic ventricular assist system with a linear actuator.
abstract: An electrohydraulic ventricular assist system with a linear actuator was developed, and in vitro and in vivo evaluations were performed. During in vitro evaluations this system could yield 5.6 L/min of pump flow against a mean afterload of 100 mmHg. Durability tests were performed for more than 4 months. The system was implanted in three goats and a maximum pump flow of 4.2 L/min was obtained against a mean afterload of 100 mmHg, and 3.2 L/min against 130 mmHg. These evaluations have proven that the system can maintain stable hemodynamics under various conditions.
