Abstract
A balloon pump system including catheter-mounted pumping balloon configured to be positioned within a desired body passageway to pump a fluid through the body passageway. A stent is percutaneously deployed within the body passageway. The pumping balloon is percutaneously deployed within the stent such that the stent is interposed between the pumping balloon and the walls of the body passageway. The stent substantially limits the compliance of the body passageway, preventing the passageway in the vicinity of the pumping balloon from significantly expanding or contracting in response to forces generated by inflation and deflation of the pumping balloon. As a result, a volume of fluid substantially equivalent to a change in volume of the pumping balloon is displaced when the pumping balloon is inflated or deflated.
