Abstract
A stent deployment system and method wherein a two balloon catheter is used to expand the stent within a body lumen. The balloons are concentrically arranged about a dual lumen catheter wherein the inner balloon is smaller than the outer balloon. By first inflating the smaller balloon to expand only the center section of the stent, the stent undergoes substantially all of its longitudinal contraction before the ends make contact with the lumen tissue upon inflation of the larger outer balloon.
