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.
A stent comprising a plurality of serpentine tubular segments having alternating peaks and troughs, serpentine tubular segments which are adjacent one another connected by a plurality of connectors, each connector having a first end which extends from a position substantially midway between a peak and a trough on one serpentine tubular segment, a second end which extends from a position substantially midway between a peak and a trough on an adjacent serpentine tubular segment, and a central loop portion between the first and second ends, at least a portion of each loop portion disposed between one of the peaks on one tubular segment and one of the troughs on an adjacent tubular segment.
