This article on continuous-flow device technology engages in an in-depth discussion on the engineering aspects of continuous-flow devices. The authors examine the energy transfer mechanics of centrifugal versus axial devices, and the impact of novel noncontact pump bearings. Furthermore, this article reviews the relationship between continuous-flow pump speed, flow, and pressure gradients across the device. Potential future advances in pump design with greater algorithmic responses to changes in patient physiology are also considered.
