摘要：
A tube for insertion into a body passageway of a patient includes a generally elongated tubular member having a proximal portion, a distal portion, a lumen extending between the proximal portion and the distal portion, and at least one aperture at the distal portion sized and positioned for passage of fluid material therethrough from the lumen to a target area in the body passageway. The tubular member is structured such that the distal portion is selectively movable between the generally elongated configuration and a shaped configuration. A length of the distal portion is provided with one or more echogenic members disposed therealong such that the distal portion length is visible under ultrasound visualization when in the shaped configuration.
