Initial hydrodynamic study on a new in axial flow pump: Dynamic aortic valve

摘要

Rotary blood pumps have been researched as implantable ventricular assist devices for years. To further reduce the complex of implanted axial pumps, the authors proposed a new con- cept of intraaortic axial pump, termed previously as "dynamic aortic valve (DAV)". Instead of being driven by an intraaortic micro-electric motor, it was powered by a magnetic field from outside of body. To ensure the perfusion of coronary artery, the axial flow pump is to be implanted in the posi- tion of aortic valve. It could serve as either a blood pump or a mechanical valve depending on the power input.
