摘要： 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 and an arterial segment. 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 also includes a lateral opening, is separate from the venous segment, and is removably seatable in the recess provided by the venous segment. In one embodiment, the distal region is un-split, but includes symmetrically opposed lateral openings, as well as distal openings, in communication with the first and second lumens for providing a functional stagger for blood flow in both forward and reverse catheter flow directions.

摘要： 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.

摘要： A catheter for vascular insertion, including a catheter body defining a first lumen and a second lumen, and including a distal region. The distal region includes an atraumatic nose portion defining a first distal opening in fluid communication with the first lumen, and a second distal opening in fluid communication with the second lumen. The distal region also includes a first lateral opening defined by the catheter body and in fluid communication with the first lumen, and a second lateral opening defined by the catheter body and in fluid communication with the second lumen. One or both of the first and second lateral openings may be defined by an angle cross-cut through an outer perimeter of the catheter body.

摘要： A multi-lumen catheter including an elliptical cross-sectional profile configuration that enhances fluid flow rate while minimizing the average diameter of the catheter body is disclosed. In one embodiment the catheter includes an elongate catheter tube defining a plurality of lumens. At least a portion of the longitudinal length of the catheter tube may define an elliptical cross section, in turn defined by a major axis and a minor axis. In one embodiment, a ratio of the major axis to the minor axis of the elliptical cross section is between about 1.3 and about 1.4. The catheter body can define two, three, or more lumens. In one embodiment, a dual-lumen catheter tube includes an aspect ratio of about 1.1:1, and each lumen thereof includes an inner surface defined by a plurality of radii and an hourglass-shaped septum.
