Improved exterior stent and its use

摘要

A support apparatus and its use is provided comprising a substantially support layer with an inside surface and an outside surface; and a securing element for securing the support layer to the exterior of a body lumen. The method for implanting the support to the exterior of a body lumen comprises providing for an exterior support, inserting the stent around a desired location on the exterior of the lumen, and providing for controlled expansion of the lumen such that it contacts the support sufficiently to secure it to the lumen.
