Abstract

The long-term application of blood pump systems on the basis of conventional displacement concepts involves many insufficiencies due to unavoidable characteristics of the mechanical function which provoke inevitable material wear and embrittlement. The consequent desire to avoid all sorts of material loading has led to the new concept of the free-floating, magnetically suspended rotor blood pump [1–3]. This concept has found application in some laboratory models of blood pump, and in vitro results with these pumps have been published [4, 5]. In the following, we discuss the characteristics of these types of pump operating on a circulatory system and the advantages displayed in vitro.
