摘要： A multi-lumen catheter comprising a loop-like structure at the distal portion of the catheter is disclosed herein. In one variation, the loop-tip catheter comprises a dual lumen catheter and a loop-like structure at the distal end of the catheter. The loop-like structure includes at least one lumen, which is in fluid communication with at lease one of the two lumens in the dual lumen catheter. One or more ports are provided on the loop-like structure for accessing the lumens within the loop. In another variation, the loop-tip catheter is configured with an arterial inlet positioned on an inner surface of the loop, while a venous outlet is positioned on an outer surface of the loop. Methods for making and using variations of the loop-tip catheter are also disclosed herein.

摘要： A catheter assembly includes a catheter, a tubular structure affixed to an exterior surface of the catheter, and a stabilizing cuff affixed to, and at least partially embedded within, the tubular structure. The tubular structure may include a tapered surface extending from an end of the tubular structure to an exterior surface of the catheter. A method of manufacturing a catheter assembly may include positioning a tubular structure about a catheter, positioning a stabilizing cuff near the tubular structure, and partially embedding at least a portion of the stabilizing cuff within the tubular structure while shaping the tubular structure to form a tapered surface. A temporary sleeve may be positioned about the tubular structure prior to shaping the tubular structure. The tubular structure may also be preformed to include a tapered end prior to positioning the tubular structure about the catheter.

摘要： A split-tip catheter for placement within the vasculature of a patient and for use in hemodialysis or other suitable procedures is disclosed. In one embodiment, the split-tip catheter includes a catheter body that defines a first lumen and a second lumen. The catheter body further comprises a split distal region, including a venous segment that defines a distal portion of the first lumen and an arterial segment that defines a distal portion of the second lumen. The venous segment includes a recess extending proximally of a nose portion; and a lateral opening in fluid communication with the first lumen. The arterial segment is separate from the venous segment and is removably seatable in the recess provided by the venous segment such that it “nests” therein. The arterial segment also includes a lateral opening in fluid communication with the second lumen.
