Patent number: 8696614Abstract: 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.Type: GrantFiled: November 11, 2011Date of Patent: April 15, 2014Assignee: C. R. Bard, Inc.Inventors: Colin S. Gregersen, Ryan T. Moehle, Ryan C. Patterson, William D. Woodley, Mark E. Walton

Patent number: 8636700Abstract: 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.Type: GrantFiled: January 20, 2012Date of Patent: January 28, 2014Assignee: C. R. Bard, Inc.Inventors: Ryan T. Moehle, Charles Farnworth, Dwight T. Hibdon, Ryan C. Patterson

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.Type: GrantFiled: March 6, 2006Date of Patent: January 24, 2012Assignee: C. R.

Patent number: 8092415Abstract: A catheter assembly for use in accessing a vasculature of a patient during renal replacement or other therapies is disclosed. In one embodiment, the catheter assembly includes a catheter body that defines first and second lumens. The catheter body defines a distal tip region that includes a venous lateral opening that is in fluid communication with the first lumen and includes a distal-facing portion. The distal tip region further includes an arterial lateral opening that is in fluid communication with the second lumen, includes a distal-facing portion, and is substantially un-staggered with respect to the venous lateral opening. A distal end opening is defined on the distal tip region and is sized to pass a fluid therethrough. In one embodiment, the distal end opening is in fluid communication with a third lumen of the catheter body that can withstand high fluid flow rates associated with power injection of contrast media.Type: GrantFiled: October 31, 2008Date of Patent: January 10, 2012Assignee: C. R. Bard, Inc.Inventors: Ryan T. Moehle, William R. Barron, Scott W. Sanders

Patent number: 7465286Abstract: 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.
