摘要：
A percutaneous pumping system for providing hemodynamic support to a patient includes a pumping sleeve that defines a lumen extending along the length of the pumping sleeve. The pumping sleeve is configured and arranged for insertion into patient vasculature. At least one rotatable magnet is disposed in the pumping sleeve. 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 is coupled to the at least one magnet. Rotation of the at least one magnet causes a corresponding rotation of the at least one impeller. An anchoring arrangement is coupled to the pumping sleeve. The anchoring arrangement is configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature.
