Stent
First Claim
1. A stent, the stent comprising a plurality of bands interconnected by U shaped links forming a plurality of rows, adjacent rows of U shaped links being 180°
- out of phase with one another, each U shaped link having a first end extending from a region of attachment on one band and a second end extending from a region of attachment on another band, wherein the region of attachment on the one band and the region of attachment on the another band are circumferentially offset from one another by one half wavelength.

Abstract
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.
