Maintaining the patency of indwelling drainage devices is critical in preventing further
complications following an intraventricular hemorrhage (IVH) and other chronic disease …

Here we report on the development of polyimide-based flexible magnetic actuators for
actively combating biofouling that occurs in many chronically implanted devices. The thin …

The degree of hemolysis as a function of surface roughness value and roughened area
under shear flow conditions was investigated using a rotational shear stressor. The shearing …

We developed a simple in vitro antithrombogenic testing method using a mock circulation
system as used in the hemolysis tests to evaluate the antithrombogenicity of centrifugal …

Visualization of a thrombus is very important in the development of various artificial organs
and extracorporeal circulation devices. This paper presents an application of electrical …

Mechanical shaft seal bearing incorporated in the centrifugal blood pumps contributes to
hemolysis and thrombus formation. In addition, the problem of durability and corrosion of …

Secondary flow in the centrifugal blood pump helps to enhance the washout effect and to
minimize thrombus formation. On the other hand, it has an adverse effect on pump efficiency …

In order to investigate the internal flow field of an axial blood pump, two‐dimensional (2D)
particle image velocimetry (PIV) was applied to test the blood pump under three different …

We have developed a microporous covered stent (MCS) for the treatment of intracranial
aneurysms (IAs). MCS promotes intentional thrombosis in the IA by blood stagnation and …

The National Institute of Advanced Industrial Science and Technology (AIST) monopivot
magnetic suspension centrifugal pump (MC105) was developed for open‐heart surgery and …
