Abstract
Described are pumps structured for moving fluids with pulsatile flow. The pumps lack valves and pistons and provide pulsatile flow through the gentle rotation of a single, one-piece, sliding vane. The vane is situated inside a slot of a rotary cylinder positioned in a hollow central opening of a housing. Generally, the vane makes minimal contact with the walls of the housing. A gap positioned between the vane and the walls and provides pulsatile fluid movement through the pump with low shear stress on the fluid. Also described are fluidic systems connected to the pumps and methods of operating the pumps and systems.
