摘要：A balloon fold design for efficient expansion of a side branch assembly in abifurcated stent. The design involves forming a cup allangement by folding the radial end

of the side branch balloon structure into the luminal end of the side branch balloonstructure and then folding the cup down into an orderly discus arrangement. The foldingpattern allows for the side branch balloon structure to inflate in a sweeping rotationalmanner efficiently pushing the side branch assembly petals out and away from the mainbody of the stent with a low risk of the balloon becoming entangled or damaged by itscontact with the petals. The design also allows for the expansion force to be applied atthe appropriate time in the optimally needed direction by initially being oriented in apredominantly circumferential direction which is gradually shifting to a predominantlyradial direction. In addition, the fold design reduces the overall volume and profile of theside branch balloon structure.
