A hemodynamic flow assist device includes a miniature pump, a basket-like cage enclosing and supporting the pump, and a motor to drive the pump. The device is implanted and retrieved in a minimally invasive manner via percutaneous access to a patient's artery. The device has a first, collapsed configuration to assist in implantation and a second, expanded configuration once deployed and active. The device is deployed within a patient's aorta and is secured in place via a self-expanding cage which engages the inner wall of the aorta. The device includes a helical screw pump with self-expanding blades, sensors, and anchoring structures. Also disclosed is a retrieval device to remove the hemodynamic flow assist device once it is no longer needed by the patient and an arterial closure device to close the artery access point after implantation and removal of the hemodynamic flow assist device. The hemodynamic flow assist device helps to increase blood flow in patients suffering from congestive heart failure and awaiting heart transplant.
