Percutaneous blood pump with articulating rigid length

A blood pump comprising:

• an impeller assembly comprising a first magnet, an impeller shaft coupled with the first magnet, an impeller coupled with the impeller shaft, and an impeller housing that houses the first magnet, the impeller shaft, and the impeller;
• a motor assembly comprising a second magnet, a drive shaft coupled with the second magnet, a motor coupled with the drive shaft, and a motor housing that houses the second magnet, the drive shaft, and the motor;
• and
• a resilient connector coupling the impeller housing with the motor housing and configured to bias the impeller housing and the motor housing to an axial configuration and allow the impeller housing and the motor housing to articulate relative to one another.

A method of using a blood pump, the method comprising:

• inserting the blood pump into vasculature of a patient, the blood pump comprising a motor housing and an impeller housing configured to articulate relative to one another;
• advancing the blood pump through the vasculature, wherein the motor housing and the impeller housing are configured to articulate relative to one another around curvatures in the vasculature;
• and
• positioning the blood pump at a location proximate an aortic valve of the patient, wherein the motor housing and the impeller housing are configured to axially align with one another at the location proximate the aortic valve.
