Considerations to Achieve Pulsatility for Left Ventricular Assist Devices through BLDC Motor by Open Loop Control System

Abstract

Abstract: Ventricular Assist Devices (VADs) and Total Artificial Heart (TAH) are used to replace the diseased heart and play a major role in saving the lives of the people. Left Ventricular Assisting Devices are the mechanical circulatory devices which play a key role in assisting patients who are suffering from different heart problems. In earlier stages, pulsatile flow devices are used, and later they are switched to continuous-flow devices. Though these devices have several advantages they have reported several complications during working. To avoid these complications, several trails were being conducted. In this paper, the work is done on achieving the pulsatility in Ventricular Assisting Devices. The open-loop control system has been implemented which is used to get different speeds of the BLDC motor to achieve the pulsatile flow in the device. The results are compared to the earlier experiment results and are tabulated.
