Abstract
A stent is disclosed that generates an elevated degree of scaffolding to a bodily vessel while retaining a highly flexible structure. In one embodiment, a stent includes an essentially tubular body formed by a web structure that is configured to expand from a contracted delivery configuration to an expanded deployed configuration and that is composed of a plurality of longitudinally adjacent web rings. Those web rings are formed by a plurality of web elements disposed circumferentially around the longitudinal axis of the stent and adjoined one to the other with a junction bend. Each junction bend in a first web ring is coupled to another junction bend in a neighboring ring with as-shaped connector, and the coupled junction bends are not longitudinally aligned but are instead laterally offset.
