Abstract: An implantable blood pump includes a housing defining an inlet and an outlet and a flow path therethrough. A rotor is disposed within the housing. A stator is disposed within the housing, the stator being configured to rotate the rotor when a current is applied to the stator. A volute is disposed distal to the rotor proximate the outlet, the volute including a tongue composed of a piezoelectric material.

Abstract: A method of controlling a blood pump including executing a control command to temporarily displace an impeller of the blood pump within a pump housing from a first axial position relative to the pump housing to a second axial position a distance away from the first axial position using a vector control method, and causing the impeller to move from the second axial position to a third axial position, the third axial position including a positive and a negative displacement of the impeller relative to the first axial position.

Abstract: A method of responding to an adverse event associated with an implantable blood pump including detecting the adverse event, reducing a pump speed of the blood pump relative to a set pump speed in response to the detected adverse event, and determining whether at least one of a group consisting of the adverse event and a second adverse event is present following the reducing of the pump speed of the blood pump. If the at least one of the group consisting of the adverse event and a second adverse event is not present, the method includes increasing the pump speed to the set pump speed and if the at least one of the group consisting of the adverse event and a second adverse event is present while increasing the pump speed to the set pump speed, the method includes reducing the pump speed to a maximum safe operating speed.
