Abstract
Delivery systems for expandable elements, such as stents or scaffolds having spikes, flails, or other protruding features for penetrating target tissue and/or delivering drugs within a human patient are described along with associated methods for using such systems. The delivery systems can be provided with a stent that is positioned over an inflatable balloon for expansion and delivery of the stent to a target delivery location. By positioning the stent over and about the inflatable balloon, the stent is ready to be expanded by the balloon immediately upon unsheathing with respect to the outer shaft. Additionally or alternatively, a stent can be positioned in an axially offset arrangement with respect to a balloon to reduce the need for space required by overlapping components.
