Abstract
An intra-aortic balloon pump condensation prevention system comprising a water vapor extracting element. In one embodiment, the water vapor extracting element may comprise a Nafion tube. Said Nafion tube absorbs water vapor in the intra-aortic balloon catheter shuttle gas. The water is then extracted from the Nafion tube by means of a vacuum supply or a dry purge gas. In another embodiment, the water vapor extracting element may comprise a cooled coiled section of tubing. Water vapor which condenses in said coiled section of tubing migrates towards a sump as a result of the intermittent one-way flow of shuttle gas through the water vapor extraction element.
