Abstract
The present invention relates to tissue-supporting medical devices and drug delivery systems, and more particularly to tubular flexible stents that are implanted within a body lumen of a living animal or human to support the organ, maintain patency and/or deliver drugs or agents. The tubular flexible stent has a cylindrical shape defining a longitudinal axis and includes a helical section having of a plurality of longitudinally oriented strut members and a plurality of circumferentially oriented hinge members connecting circumferentially adjacent strut members to form a band. The band is wrapped about the longitudinal axis in a substantially helical manner to form a plurality of helical windings. At least one connector member extends between longitudinally adjacent helical windings of the band.
