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： A catheter hub includes a hub body defining a first lumen and a second lumen. At least a portion of the first lumen defines a first longitudinal axis, and at least a portion of the second lumen defines a second longitudinal axis. A cap coupled to the hub body is configured and arranged in a non-intersecting orientation relative to the first and second longitudinal axes. A first arm and a second arm each includes a distal portion coupled to the hub body, and a proximal portion which is movable, in a direction toward a respective longitudinal axis, into releasable engagement with the cap.

摘要： A catheter assembly includes an elongate member and a balloon. The elongate member defines at least one lumen and an outer surface. The outer surface defines at least one opening in fluid communication with the at least one lumen. The balloon is disposed within the at least one lumen. The balloon is inflatable such that a portion of the balloon expands from the at least lumen through the at least one opening. The expansion of the balloon increases the flow restriction through the at least one opening compared to the flow restriction through the at least one opening when the balloon is in a deflated condition. Methods for using a catheter assembly to remove occlusive material from a catheter are also described.
