Abstract
A catheter assembly is provided for use in delivering and implanting a stent in a body lumen, such as in a coronary artery. An elongated catheter body includes an expandable member or balloon having a folded configuration and an expanded configuration wherein a plurality of pre-formed grooves extending generally circumferentially around the balloon when the balloon is in its folded configuration. An intravascular stent is removably crimped over the balloon and is at least partially retained on the balloon by the grooves. Upon inflation of the balloon, the grooves will flatten out thereby releasing the stent and allowing the stent to expand radially outwardly into contact with the body lumen or coronary artery.
