摘要:
A radially expandable stent comprising a plurality of spaced band-like elements and intersecting links is disclosed. The band-like elements have a generally serpentine configuration to provide continuous waves of generally sinusoidal character to each band-like element. The waves are characterized by a plurality of peaks and troughs taking a generally longitudinal direction along the cylinder such that the waves in the band-like elements open as the stent is expanded from a first diameter to a second diameter. The intersecting links are substantially U-shaped and terminate in first and second shanks. The first shank of a link emanates from a region between a peak and trough on a band-like element and the second shank of the link emanates from a region between a peak and trough on an adjacent band-like element.
