A catheter assembly is disclosed comprising a catheter, a tubular structure affixed to an exterior surface of the catheter, and a stablizing 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 is also disclosed. For example, such a method may comprise positioning a tubular structure about a catheter, positioning a stabilizing cuff near the tubular structure, and partially embedding at least a portion of the stablizing 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 may also be performed to include a tapered end prior to positioning the tubular structure about the catheter.

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.

Methods and apparatuses for facilitating removal of a catheter from a patient are provided. A catheter removal device is disclosed comprising a gripping mechanism with at least two members each member having a proximal end and distal end. The distal end of the gripping mechanism having opposing clamping members which, when closed, approximate at least a portion of the outer circumference of a catheter securement device. The proximal end of the gripping mechanism has two handle members each having a loop structure to accommodate the thumb or finger, for example, of a medical practitioner. A middle portion of the gripping mechanism has a shank member wherein the at least two members are coupled together at a pivot point. A distal end of the clamping members has a taper to allow for dilation of tissue up to the location of the catheter securement device.

A reinforced multi-lumen catheter and method of manufacturing the same. An assembly for manufacturing the multi-lumen catheter includes a catheter body substrate including a septum, one or more mandrels, a reinforcing element and one or more sleeves. The septum may have a distal region with a cross-sectional thickness greater than that of a proximal region. The septum can be separately formed. The septum can be split along a length of the distal region. The reinforcing element can be positioned over at least a proximal region of the catheter body substrate.
