Abstract

A stent graft (5) comprises a tubular graft member (4), and a plurality of sloping stent members (3) substantially coaxial with and coupled to the tubular graft member (4). Each of the sloping stent members (3) comprises multiple uneven apexes characterizing a round tubular configuration with a distal end and a proximal end disposed about a longitudinal axis. The distal apexes of the sloping stent member (3) are arranged in substantially the same plane substantially horizontal to the longitudinal axis of the sloping stent member and the proximal apexes are arranged in a sloping plane oblique to the longitudinal axis.
