ABSTRACT:
Disclosed herein are embodiments of long-term ambulatory intra-aortic balloon pump systems for providing left ventricular cardiac assistance to a patient. The systems can comprise an external drive system for supplying a compressed fluid, the drive system operating in accordance with a control program stored in memory, an intra-luminal balloon pump having an elongate inflatable chamber positionable to be lying completely within a descending aorta of the patient, and a percutaneous access device. The percutaneous access device can be a biocompatible implantable portal comprising a communicative passage through an interior bore and an exterior having a neck region adapted to promote autologous cell growth thereon in an implantable region, the neck region having a plurality of channels extending about the neck region.
