Abstract: A stent delivery catheter for positioning a stent across a lesion of a blood vessel is disclosed. The catheter includes an inflation balloon coupled to a distal region of the elongate shaft of the catheter and a stent loaded on the inflation balloon. The catheter may also include an occlusion balloon having a proximal waist secured to the elongate shaft and a distal waist secured to the elongate shaft. The occlusion balloon includes a first folded-over portion extending distal of the distal waist to a distalmost extent of the occlusion balloon and a second folded-over portion extending proximal of the proximal waist to a proximalmost extent of the occlusion balloon. The catheter further includes a fluid discharge port located distal of the occlusion balloon for discharging a lubricious fluid exterior of the elongate shaft toward the stent to facilitate advancing the stent across an occlusion.
