Abstract
A stent is deployed within a body passageway. The stent is configured to curl a varying degree upon itself as the stent is inserted into the passageway depending on the size of the passageway. In this way a single size stent may be employed in different size passageways. The stent may have a generally rectangular shape or other shape. The stent may be made of one or more materials. For example, a spine of the stent may be made of a material different than a material used for the outer edges of the stent. The edges of the stent curl towards the spine during insertion into the passageway without any further manipulation of the stent or by application of any additional mechanical means. The stent may have a varying thickness and/or width along the longitudinal axis of the stent.
