Abstract:
1. A balloon catheter comprising a balloon inflation system, the balloon inflation system comprising a side branch balloon structure, capable of at least partially expanding a side branch structure of a bifurcated stent, wherein: the side branch balloon structure has an inflated configuration having a radial end, a luminal end and a side wall there between, where the radial end is distal from the luminal end and the luminal end is abutting the balloon catheter and; an un-inflated configuration and when in the un-inflated configuration the side branch balloon structure is in-folded in a pleated or overlapping fold pattern from a cup fold where the radial end is flush with the luminal end and the side wall extends entirely around a cavity having an open end opposite the radial end, wherein the pleated or overlapping fold pattern permits orderly unfolding when the side branch is inflated; wherein the side branch balloon structure is in the un-inflated configuration.
