Publication number: 20220273858Abstract: A subcutaneous tunneling device includes a shaft having a bend, a catheter connector extending from a distal end of the shaft distal of the bend, and a sleeve. 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

Publication number: 20190240393Abstract: 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: ApplicationFiled: April 15, 2019Publication date: August 8, 2019Inventors: Colin S. Gregersen, Ryan T. Moehle, Ryan C. Patterson, William D. Woodley, Mark E. Walton

Publication number: 20160121040Abstract: A split-tip catheter for placement within the vasculature of a patient and for use in hemodialysis or other suitable procedures. In one embodiment, the split-tip catheter includes 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 includes 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 may taper distally from a first outer perimeter to a second outer perimeter smaller than the first outer perimeter.Type: ApplicationFiled: January 8, 2016Publication date: May 5, 2016Inventors: Colin S. Gregersen, Ryan T. Moehle, Ryan C. Patterson, William D. Woodley, Mark E. Walton

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
