摘要： An infusion device (10) for use in delivering an infusate from an elongated infusion segment (18) along an elongated section of a body vessel with either a relatively symmetric infusate distribution profile (70) or asymmetric infusate distribution profile (70) that concentrates infusate delivery proximally or distally along the infusion segment (18). The infusion segment (18) is formed with an infusate distribution manifold (37) having proximal and distal manifold end openings (52, 54) to which infusate is delivered in equal amounts to effect the relatively uniform infusate distribution profile (70) or in relative proportions to effect the asymmetric infusate distribution profile (70). In differing embodiments, the infusate delivery is either fixed or may be adjusted by a proximal adjustable valve mechanism (58, 60). The infusate is delivered to the proximal and distal manifold end openings (52, 54) through first and second separate infusion lumens (42, 37).
