1. An interventional device, comprising:
an elongated member having a wall and an interior lumen, the elongated member including a plurality of fenestrations extending through the wall and exposing the lumen, the plurality of fenestrations defining a plurality of axially extending beams and a plurality of circumferentially extending rings arranged in an imperfect ramp pattern,
wherein no set of three successive segments within the imperfect ramp pattern are spaced according to the same rotational offset, and
wherein the imperfect ramp pattern includes an imperfect rotational offset from one segment to the next, the imperfect rotational offset being equal to a constant value±a variable modifying value,
wherein the elongated member is formed from a succession of segments, each segment including a first pair of circumferentially opposed beams and a second pair of circumferentially opposed beams which are rotationally offset by about 90 degrees from the first pair of beams.
