Abstract

See full text

A blood-pumping device comprises a cavity with a U-shaped wall comprising two straight regions connected by an arch-shaped region and a U-shaped tube aligned with the U-shaped wall of the cavity to provide a support for the U-shaped tube, wherein the U-shaped tube comprises two straight regions connected by a semicircular region. The blood-pumping device further comprises an arm rotatable about a center point of the semicircular region, wherein the arm holds two wheels a distance from each other such that upon rotation of the arm the wheels roll along the U-shaped tube while putting pressure on the U-shaped tube, wherein the arch-shaped region of the U-shaped wall of the cavity comprises a recessed portion so that the wheels of the arm impose less pressure on the tube at the recessed portion and upon rotation of the arm generates a pulsating blood flow.
