Abstract:
1. A stent comprising a length of helically wound serpentine wire extending continuously between opposing ends of the stent wherein multiple revolutions of the wire about a longitudinal axis of the stent result in a generally tubular form, said serpentine wire incorporating a plurality of apices along the length of the wire that are oriented alternately to point toward opposite ends of said stent, with a space between adjacent revolutions of the helically wound serpentine wire wherein one revolution has a first apex that is oriented to point to one end of said stent, and an adjacent revolution has two adjacent apices that are oriented to point toward the opposite end of the stent wherein first apex points between the two adjacent apices, wherein the first apex is interconnected by a pair of film webs to the two adjacent apices, wherein the film webs serve to limit axial elongation of the stent, and wherein the film webs have a length extending between the apices that they interconnect and wherein the film webs are of narrower width at the middle of their length than at ends of their length.
