Abstract
Blood vessels and other body lumens are stented using multiple, discrete stent structures, or continuous coiled or mesh stent structures. Stent structures may be a balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sites. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having a deployment mechanism for deploying one or more stents of selectable length into the vessel.
