Abstract
A device for implanting a radially expandable stent that includes a balloon catheter having a balloon formed of a material having a memory so that when inflated to a first pressure the two end sections of the balloon expand to a first diameter as the waist therebetween expands to a lesser diameter. The stent is mounted over the waist section of the balloon and is thus locked between the two end sections during initial inflation to the first pressure. Once locked in place, the pressure inside the balloon is raised to a second higher level whereby the entire balloon expands to a larger diameter thus radially expanding the stent.
