Abstract: A stent includes an expandable, generally tubular wall structure that can be radially expanded between a collapsed tubular configuration and an expanded and supportive tubular configuration. The stent defines a longitudinal axis. At least one penetrating projection (defining a projection axis) is attached to the wall of the stent. The penetrating projection supports a treatment drug and is pivotal between a stowed position, wherein the projection axis lies generally parallel to the longitudinal axis of the stent, and a penetrating position, wherein the projection axis lies generally perpendicular to the longitudinal axis of the stent and directed radially outward. The penetrating projection is in it's stowed position when the stent is in it's collapsed tubular configuration and moves to it's penetrating position when the stent expands to it's expanded and supportive tubular configuration.
