Abstract
Apparatus and methods for stent delivery provide for dilatation at a treatment site as well as stent delivery, using the same stent delivery apparatus. Apparatus generally include a catheter having at least one expandable member, at least one stent positionable thereon, and a sheath disposed over the expandable member and the stent. Some embodiments include separate expandable members for dilatation of a lesion and for stent expansion, while other embodiments use the same expandable member for both. In some embodiments a stent includes multiple separable stent segments. In various embodiments, self-expanding stents may be used. Methods involve positioning a stent delivery device at a treatment site, expanding an expandable member to dilate at least a portion of a lesion at the treatment site, and expanding (or allowing to expand) a stent at the treatment site.
