摘要： The present invention includes systems, methods and apparatus. A system in accord with the present invention may include an intraluminal patch sized to fit within a lumen and an expandable therapeutic delivery device. The patch in this embodiment may have an adhesive region on an exposed surface and a drug reservoir region in communication with the exposed surface. By comparison, a method employing the present invention may include placing an intraluminal patch over an expandable delivery device, advancing the delivery device and the expandable patch to a target site, expanding the delivery device so that the patch adheres to the target site, and contracting and withdrawing the delivery device. In so doing the patch may remain to emit a drug to the target site over a sustained period of time.
