Patent number: 11918758Abstract: A catheter assembly for use in accessing a vasculature of a patient is disclosed. In one embodiment, the catheter assembly includes a catheter body that includes a flattened oval outer surface and 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 in fluid communication with a power injectable third lumen. In another embodiment, the first and second lumens each generally include a reniform cross-sectional shape. In yet another embodiment, a dual-lumen catheter includes first and second lumens that each define a modified ellipse cross-sectional shape.Type: GrantFiled: December 23, 2019Date of Patent: March 5, 2024Assignee: C. R. Bard, Inc.Inventors: Kelli D. Oborn, Ryan T. Moehle, William R. Barron

The catheter connector can include a body having a gripping portion, and a barbed extension distal of the body configured for insertion into a lumen of a catheter. The sleeve is slidably mounted on the shaft, and has a retracted position exposing the catheter connector to permit a distal end of a catheter to be coupled thereto, and an extended position covering the catheter connector and the distal end of the catheter.Type: ApplicationFiled: May 23, 2022Publication date: September 1, 2022Inventors: Colin S. Gregersen, Ryan T. Moehle, Ryan C. Patterson, William D. Woodley, Mark E. Walton

Patent number: 11338075Abstract: A split-tip catheter for placement within the vasculature of a patient and for use in hemodialysis or other suitable procedures, and methods of use. The split-tip catheter can include a catheter body defining a first lumen and a second lumen, and a split distal region extending from a distal end of the catheter body. The split distal region can include an arterial segment defined by an outer wall enclosing an arterial segment lumen, the arterial segment lumen in fluid communication with the catheter body first lumen, and a venous segment defined by an outer wall enclosing a venous segment lumen, the venous segment lumen in fluid communication with the catheter body second lumen, the venous segment outer wall extending from the catheter body distal end to a distal nose portion. The distal nose portion can taper from a first outer perimeter to a second smaller outer perimeter.Type: GrantFiled: April 15, 2019Date of Patent: May 24, 2022Assignee: C. R.
