ABSTRACT:
An expandable, implantable medical device, such as an intraluminal stent (10) fabricated from polymeric materials, includes a plurality of elongated struts (16) in consecutive series and alternating stress concentration junctions (18) interconnecting ends of adjacent struts (16). When the stent (10) is in an expanded condition, the adjacent struts (16) form expanded substantial V-shapes and stresses are concentrated within the junctions (18). The junctions (18) define pivot points (P) for the respective attached, adjacent struts (16). Each of the pivot points (P) is located substantially on a line bisecting the V-shapes formed by the struts (16), when the stent (10) is expanded.
