ABSTRACT:
An inflatable balloon pump can be anchored with respect to a wall of the aorta for endoscopic surgical positioning with respect to the aorta of the patient. After engagement of the anchor member in an endoscopically selected location of the aorta, the inflatable balloon pump can be cyclically inflated and deflated to assist the cardiac function based on measured clinical parameters of the patient. The balloon pump can include tapered longitudinal ends and/or be segmented into a plurality of pumping chamber subsegments, each pumping chamber subsegment separated by a flexible power conduit link, where the diameter of the pumping chamber subsegments are independent of one another. Anchor members can be provided located adjacent at least one longitudinal end of the pump, or each longitudinal end of each inflatable chamber defining the pump, or sheathing at least one of the inflatable chambers defining the pump.
