Abstract
A method of controlling an implantable blood pump including a housing having a proximal portion including an inlet, a distal portion including an outlet, and an impeller therein, the method including detecting when a pressure in the housing exceeds a pressure threshold and executing a first vector control command to displace the impeller axially in a distal direction from a primary position to a secondary position different than the primary position in response to the pressure exceeding the pressure threshold.
