Abstract:
The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member comprised of a link and a U-shaped member has relief dimples formed in the curved portion of a valley to reduce localized stress and thereby reduce fatigue failure that can lead to link structure failure.

Claim (Index 1):
A longitudinally flexible stent for implanting in a body lumen, comprising:\n a first cylindrical ring, a second cylindrical ring, a third cylindrical ring, up to an Nth cylindrical ring, the cylindrical rings being generally independently expandable in the radial direction and generally aligned on a common longitudinal axis; each of the cylindrical rings having an undulating pattern of peaks and valleys, the undulating pattern of each of the cylindrical rings being in phase with the undulating pattern of each of the adjacent cylindrical rings; each of the cylindrical rings being interconnected by links to one of the adjacent cylindrical rings so that the cylindrical rings form a longitudinally flexible stent; and a Y-shaped member is formed by one of the links connecting to a curved portion of valley, a first relief dimple and a second relief dimple are formed in the curved portion of the valley.
