The stent is supported in a reduced radius delivery state to facilitate delivery to a treatment site in a body lumen, by advancing the device over a previously positioned guidewire. An opening at the distal end of the device receives the guidewire into a guidewire lumen (46) of the interior catheter (38). A second opening (52) through the catheter wall just proximally of the support region allows passage of the guidewire to the exterior of the catheter, whereby the guidewire is contained within the device only along the distal end region. The retaining means (20) can include an exterior catheter (20) surrounding the interior catheter (38) and stent, and moveable axially relative to the interior catheter (38). A portion of the guidewire proximally of the second opening (52) is contained between the catheters, and can be removed from the exterior catheter (20) through a slit (53) running axially along the exterior catheter (20). Alternatively, the retaining means can include a pair of spaced apart sleeves (124, 126) integral with the interior catheter (112) and frictionally retaining opposite ends of the stent, to maintain the stent in the delivery state. In this case the catheter further supports a dilatation balloon (122) surrounded by the stent. The balloon (122) is expanded to free the stent from the sleeves (124, 126).
