The aim of this dissertation is to design, model, and simulate a specific type of extra-aortic cardiac assist device using the Arduino. This cardiac aid device is for patients who have a weak ventricle and low efficiency to pump blood to the circulatory system in a normal way. Part of this device is in contact with the cardiac system, which is located around the ascending or descending aorta and is filled and emptied alternately by applying pressure by the pump unit and controlling the device, which increases the energy of the patient's blood flow in diastolic and systolic phases, respectively. As a result, better blood is pumped to the circulatory system. Aortic network model with branches that include (brachiocephalic vessels, carotid arteries, etc.) are extracted through medical imaging for modeling. They are selected against high temperature environments. Blood fluid is considered to be a viscous, Newtonian fluid, slightly compressible, with quiet and turbulent assumptions. This device can increase blood energy in the diastole phase by up to 70%. The present cardiac aid device increases blood flow by 1.5 times compared to the patient without the device. This leads to better blood flow to the heart tissue itself.
