Polymeric endoluminal paving. A family of evolving methods for extending endoluminal therapeutics beyond stenting.

This article briefly reviews the background and rationale for the development of polymer paving. The process of endoluminal paving is described both in its generic form as well as in three experimental embodiments. Several experimental studies with two forms of paving, solid paving and gel paving, are reviewed. Finally, the envisioned future clinical role for both solid and gel paving is described.
