Abstract
The balloon portion of a balloon catheter for implanting a stent structure is at least initially retained laterally to a guide wire by passing the guide wire axially along the balloon inside the stent structure but not through the interior of the balloon or any permanent guide wire lumen at the location of the balloon. The initially deflated balloon may be folded laterally into a plurality of folds, and the guide wire may pass between the folds or outside the folds as desired. Guide wire lumens may be provided distally and/or proximally of the balloon. An elastic sleeve may be provided around the balloon to help keep the balloon folded prior to inflation and to help refold the balloon during and after deflation. If an elastic sleeve is provided, the guide wire may pass along the balloon inside the sleeve.
