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.

摘要： The present disclosure is directed to a method of manufacturing a catheter wherein a dual lumen catheter body and at least one distal tip member are separately formed and the at least one distal tip member is subsequently assembled to the dual lumen catheter body. The components may be assembled using a heating process or, alternatively, using adhesives.
