Abstract
AbstractThe biomedical materials that have been used in the structure of heart pumps are classified as biocompatible, and these can be metals, polymers, ceramics, and composites. Their positions in the pump vary according to the part’s function. Whereas various materials have different properties, all biomaterials chosen for cardiovascular applications should have excellent blood biocompatibility to reduce the likelihood of hemolysis and thrombosis. There are two major categories of the heart pumps; pulsatile and rotary blood pumps (axial and centrifugal) and the features of some of these materials allow them to be used in both. Rotary and pulsatile blood pump devices have to be fabricated from materials that do not result in adverse biological responses. The purpose of this review is to study the available biocompatible materials for the pulsatile and rotary blood pumps as clinically-approved materials and prototype heart pump materials. The current state of bio-compatible materials of rotary and pulsatile blood pump construction is presented. Some recent applications of surface amendment technology on the materials for heart assist devices were also reviewed for better understanding. The limitations of heart assist devices, and the future direction of artificial heart elements have been considered. This review will be considered as a comprehensive reference to rapidly understanding the necessary research in the field of biocompatible materials of pulsatile and blood rotary pumps.
Highlights
The devices that have predominantly been developed to improve the pumping function of the heart in the event of a failure are Ventricular Assist Devices (VADs) and the Total Artificial Heart (TAH)
The significant aspects that must improve on blood pumps include the miniaturization of the instrument, reducing the effect of thrombosis, and upgrading the valve materials and design
Route of manufacturing the entire artificial organs from nano-technology materials or polymer composites allow to the devices gain more adaptable properties and better efficiency in term of the mechanical properties, biocompatibility, thermal properties and destruction reducing of the pump
Summary
The devices that have predominantly been developed to improve the pumping function of the heart in the event of a failure are Ventricular Assist Devices (VADs) (pulsatile and blood rotary pumps) and the Total Artificial Heart (TAH). Transplantation is the right way for everyone having a weakened heart, or congestive heart failure to covering these cases. It is most frequently using a suitable heart pump in the left ventricle because of the most typical case of heart failure. VADs have become an increasingly useful option for patients with heart failure [1] Basing on their properties, rotary blood pumps have proved to be stronger than pulsatile pumps; these use either an axial circulation pump or a centrifugal pump. Rotary blood pumps have proved to be stronger than pulsatile pumps; these use either an axial circulation pump or a centrifugal pump Both types contain a core rotor comprising everlasting magnets. The rotors are shaped to boost the
