Abstract

A stent comprised of a valve and a scaffolding structure having components configured to allow at least a portion of the stent to decrease in diameter in response to an axial force applied to the stent. Further, the components and elements of the stent may be configured to balance transverse forces applied to the stent, thus reducing the incidence of infolding.
