Abstract
A method for manufacturing a stent delivery catheter includes the step of crimping an expandable stent over an inflatable balloon to create a balloon-stent assembly. The balloon-stent assembly is then constrained by a covering tube and a shrink wrap which act together to prevent expansion of the stent when the balloon is pressurized. Next, the balloon is pressurized. In this configuration, the assembly is heated to permanently deform the balloon by embedding the stent into the balloon surface. The result is a stent delivery catheter system in which protrusions that are formed on the balloon surface are inserted into openings in the stent wall to enhance the retention forces acting between the balloon and the stent.
