International Classification:

A61M 1/00
A61M 3/00

US Classification:

604 29, 604 43

Abstract:

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.

International Classification:

A61M 5/32

US Classification:

604175

Abstract:

A catheter assembly is disclosed comprising 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 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 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 may also be performed to include a tapered end prior to positioning the tubular structure about the catheter.
