Development of Intra-Aortic Balloon Pump with Vascular Stent and Vitro Simulation Verification

Intra-aortic balloon pump (IABP) has been widely used in the rescue and treatment of patients with cardiac insufficiency and heart failure, but IABP is not effective in increasing cardiac output. In this study, an aortic balloon pump with a vascular stent was developed, and an experimental bench for simulating heart failure in vitro was built to study the effect of a balloon pump with a vascular stent on hemodynamic changes. Experiment results have shown that compared with the traditional balloon pump, a balloon pump with a stent has higher cardiac output and counterpulsation pressure, lower systolic and diastolic blood pressure, and therefore has better performance in heart failure treatment.
