Abstract
A low profiled stent delivery system includes a balloon catheter with a balloon mounted at a first location, and a balloon expandable stent crimped about the balloon catheter at a second location. The stent expands from a crimped state to a less than fully expanded state responsive to movement of an auxiliary expander from a first configuration to a second configuration. An inner diameter of the stent in the less than fully expanded state is greater than an outer diameter of the balloon in a deflated state. After repositioning the balloon within the less than fully expanded state, the balloon is inflated to fully expand the stent.
