Design and Control of a Peristaltic Pump to Simulate Left Atrial Pressure in a Conductive Silicone Model
Date of Graduation
Bachelor of Science in Mechanical Engineering
According to the CDC, atrial fibrillation is responsible for more than 454,000 hospitalizations and approximately 158,000 deaths per year. A common treatment for atrial fibrillation is catheter ablation, a process in which a long flexible tube is guided through the femoral artery and to the source of arrhythmia in the heart, where it measures the electrical potential at various locations and converts problematic heart tissue to scar tissue via ablation. This paper details the design and control of a low-cost ($400) peristaltic pump system using repetitive control to replicate blood pressure in the left atrium in a conductive silicone model for use in modeling catheter ablation. Using repetitive control, an average root-mean-square error of 0.038 psi was achieved.
