MiFlow™ VAD

System Configuration

The MiFlow™ VAD is a mixed flow pump with axial symmetry. It utilizes the similar pump and magnetic levitation principles as the larger predecessor Levacor® VAD, however, in a geometric configuration that is optimized for its anatomic location and maximum flow rate.

The pump flow path is shown below:

The pump is configured to have a single flow path, with no secondary flow paths. Impeller blades are mounted on the rotor while stator blades to straighten out the flow are mounted on the housing at the outlet side (right side of figure).

The rotor is fully magnetically levitated using only one single axis of active control (along the axis of blood flow), with the rest of the axes (radial, tilt) being passively levitated with a unique arrangement of permanent magnets.
