Abstract:
1. A stent anchoring system for deployment in a lumen of a vessel, the system comprising: an expandable tubular member having a proximal end, a distal end, a longitudinal axis extending through the proximal and distal ends, an inner surface, an outer surface, a thickness between the inner surface and the outer surface, and a circumference in a plane perpendicular to the longitudinal axis; and a plurality of cleats extending outwardly from the outer surface of the expandable tubular member, each cleat having an outer surface, a first lateral surface, a second lateral surface, and end surfaces, wherein the first and second lateral surfaces are longer than the end surfaces, the plurality of cleats defining flow passages therebetween, wherein each cleat is positioned at a non-parallel angle to the longitudinal axis of the expandable tubular member, and each cleat is spaced apart both axially and circumferentially from an adjacent cleat and further wherein each cleat is symmetrical to each circumferentially adjacent cleat about the longitudinal axis of the tubular member.
