The first ventricular assist devices (VADs), created in 1960s, were intended for lessening insuficiency of biological heart. These pumps were heavy and of large dimensions. They pumped blood from the left ventricle through an intake valve and moved it to aorta even at a flow of 10L per minute, i.e. at a full capacity of a healthy heart.
Tiny, handy and compact ventricular assist device is smaller than a type-C battery. Its welded titanic body is equipped with a DC motor and a screw, supported by two ceramic bearings, which are the only moving parts: a rotating small titanic screw, which pumps blood from the heart to the aorta at a flow of apprx. 8.5L per minute. Ventricular assist devices increases cardiac output of a weak heart and assists to restore a normal blood flow in the whole body. Any muscle trained too little loses its “shape”, and the heart is not an exception. Consequently, this device helps patient’s heart to continue its operation and training in order to restore after diseases or surgeries.
Ventricular assist devices has been designed for decreasing patient’s dependency on mechanical support, eliminating the risk and offering a patent an opportunity of getting well as quickly as possible.
