Analysis on the effects of pulsation induced flow in mechanical circulatory support system / Nazirul Izzati Rosli

Impedance pump is a valve less pump emerging from the blood circulatory system of human that function without blade or propeller to transfer fluid. The impedance pump offers good characteristics as valve less pump to overcome clinical issues such as blood cell damaged by the rotational blades used i...
