ABSTRACT
ABSTRACT: The results of the studies of hemodynamic characteristics of the Artificial Ventricles of the heart (AV) implantable circulatory support systems and artificial heart pulsating type. A general approach to research individual housing through Computer-Aided Design (CAD) algorithm for finding the index of hemolysis obtained practical results
1 INTRODUCTION
Increased hemolysis and thrombus formation are the main problems impeding the use of implantable Left Ventricle Assist Device (LVAD) in clinical practice [1], [4]. The LVAD include an implantable unit consisting of a pump with control system and power supplies and an Artificial Ventricle (AV) with valves and connecting pipes [5-10]. Blood in such system is contacted with the inner surfaces of AV, valves, and connecting pipes. The degree of hemolysis and thrombus formation are determined by three main factors: individual housing hemocompatibility of artificial materials, valves and connecting pipes; the physiological characteristics of a person; hemodynamic characteristics of individual housing construction, valves and connecting pipes. The first factor is investigated in detail in [1] and is determined by the material, manufacturing technology, and a number of other reasons. The second problem is one of the most important in human physiology [2]. Effect of the third factor can be minimized at the design stage of new constructions in the private housing construction through CAD. In this case we take into account the geometrical design parameters and its hemodynamic properties.
