Abstract
A stent delivery system which has a stent, a catheter, and a tether. The catheter has a balloon with at least one fold. The balloon and the stent both have unexpanded configurations with smaller diameters and expanded configurations with greater diameters. The tether defines a length and has a first end connected to the unexpanded stent and a contacting span enwrapped within the fold of the unexpanded balloon. The tether holds the unexpanded stent to the unexpanded balloon and releases the expanded stent from the expanded balloon.
