Mock Circulatory System for Intra-Aortic Balloon Testing

A mock circulatory system (MCS) was constructed for testing intra-aortic balloon (IAB) temporary heart-assist devices. The MCS consists of a left heart analog, compliant arteries, peripheral resistance, and venous return. Design objectives and operating characteristics of the MCS are presented. The results of a number of studies to determine the effectiveness of intra-aortic balloon devices under conditions of simulated cardiogenic shock are reported.
