Systems and methods for making and using percutaneously-delivered pumping systems for providing hemodynamic support

A percutaneous pumping system, for providing hemodynamic support to a patient, the percutaneous pumping system comprising:

• a pumping sleeve having a length, a distal end, and a proximal end, the pumping sleeve defining a lumen extending along the length of the pumping sleeve from the proximal end to the distal end, the pumping sleeve configured and arranged for insertion into patient vasculature;
• at least one rotatable magnet disposed in the pumping sleeve, wherein the at least one first magnet is configured and arranged to be driven to rotate by a magnetic field generated external to the pumping sleeve;
• at least one impeller coupled to the at least one magnet, wherein rotation of the at least one magnet causes a corresponding rotation of the at least one impeller;
• an anchoring arrangement coupled to the pumping sleeve, the anchoring arrangement configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature;
• and
• at least two magnetic field windings disposed external to the patient during operation of the percutaneous pumping system, the windings configured and arranged to provide the magnetic field.
