Abstract
A deployment system and method for an expandable stent are described. The deployment system includes an expandable stent in an unexpanded state and a first tubular sheath having one or more first flaps extending from a distal end thereof. The one or more first flaps overlie one or more first longitudinal portions of the stent. A second tubular sheath may overlie the first tubular sheath. The deployment method includes advancing a deployment system including an expandable stent in an unexpanded state to a treatment site in a body vessel. At the treatment site, one or more second longitudinal portions of the stent are radially expanded to partially deploy the stent, and then one or more first longitudinal portions of the stent are radially expanded to fully deploy the stent. Each of the first and second longitudinal portions preferably extends from a proximal end to a distal end of the stent.
