Controller for an Axial Flow Blood Pump

Artificial Organs, 1996
Abstract: A rotary blood pump inherently provides only one noninvasive “observable‘” parameter (motor current) and allows for only one “controllable” parameter (pump speed). To maintain the systemic circulation properly, the pump speed must be controlled to sustain appropriate outlet Hows and perfusion pressure while preventing pulmonary damage caused

Numerical Simulation of an Axial Blood Pump

Artificial Organs, 2007
Abstract:  The axial blood pump with a magnetically suspended impeller is superior to other artificial blood pumps because of its small size. In this article, the distributions of velocity, path line, pressure, and shear stress in the straightener, the rotor, and the diffuser of the axial blood pump, as well as the gap zone were obtained using the ...

Characteristics of a Blood Pump Combining the Centrifugal and Axial Pumping Principles: The Spiral Pump

Artificial Organs, 1996
Abstract: Two well‐known centrifugal and axial pumping principles are used simultaneously in a new blood pump design. Inside the pump housing is a spiral impeller, a conically shaped structure with threads on the surface. The worm gears provide an axial motion of the blood column through the threads of the central cone.

Off-pump Replacement of the INCOR Implantable Axial-flow Pump

The Journal of Heart and Lung Transplantation, 2009
Owing to the actual increase of mechanical circulatory support durations, total or partial replacement of ventricular assist devices (VADs) will most certainly have to be performed with increasing frequency. Herein we report the case of a patient in whom an INCOR (Berlin Heart AG, Berlin) implantable axial-flow pump was replaced without the use of ...
