ABSTRACT:
A catheter includes a segment having a longitudinal axis. The segment includes a polymeric tube having interior and exterior surfaces separated by a wall thickness. The interior surface defines a catheter lumen which extends coaxially with the longitudinal axis. The exterior surface is sized for the tube to be passed through a patient's vasculature system. The segment further includes a substantially straight, flexible guide member disposed within the tube's wall thickness. The guide member has a longitudinal dimension extending parallel to and radially spaced from the segment's axis. The guide member is plastically deformable when bent around a bending axis perpendicular to the longitudinal dimension beyond a bending limit.
