Patent ID: 8734508

Claim:
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; a stator spaced apart from the pumping sleeve; and 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.
