TECHNICAL ASPECTS OF TOTAL ARTIFICIAL HEART DEVELOPMENT

Résumé fourni par la source

Highlights The development of a Total Artificial Heart (TAH) represents a complex engineering challenge aimed at creating a long-term replacement for the terminally failing heart. Primary efforts focus on ensuring reliable pump function and biocompatibility. The article examines key technical aspects of TAH, including pump design, material selection, and control systems, based on an analysis of current developments and scientific literature. Particular attention is paid to addressing hemocompatibility issues. One of the major technical challenges in creating a TAH remains ensuring efficient and safe long-term energy supply for the implanted device. Finding solutions in this area is critically important for the success of the technology. Abstract The article examines critical engineering aspects: the design of miniature, highly reliable pump systems (rotary/pulsatile); the development of exceptionally biocompatible materials preventing thrombosis and calcification; the creation of efficient blood flow control systems with autonomous adaptation to patient needs; and the integration of advanced energy sources and wireless transmission systems. Particular attention is paid to minimizing hemolysis and achieving hemodynamic compatibility.
