摘要：
A catheter includes an elongate shaft having proximal and distal end portions defining a longitudinal axis, and first and second tip segments. The elongate shaft and the first and second tip segments define respective first and second lumens. Each tip segment includes a proximal portion fixed relative to the distal end of the elongate shaft, and a distal portion. Each tip segment defines a side opening in fluid communication with a respective one of the first and second lumens. Each tip segment is movable between a straight configuration in which each respective tip segment is substantially parallel to the longitudinal axis, and a curved configuration in which each tip segment has a concave portion with respect to the longitudinal axis. The side openings face each other along the concave portions.
