Hub for triple lumen catheter assembly

An assembly of a triple lumen catheter, three extension tubes and a hub, comprising:

• a catheter adapted for implantation into vasculature of a patient and including at least a proximal end portion and three lumens extending therethrough for fluid transmission;
• three extension tubes each associated with a selected one of the three lumens of the catheter;
• and
• a hub body integrally joined to the proximal end portion of the catheter and to distal end portions of the three extension tubes and providing passageways extending and establishing sealed fluid communication between each extension tube and a respective selected one of the three lumens of the catheter,
• wherein the hub body contains the proximal end portion of the catheter within a distal opening and provides interior openings in communication with respective ones of the three lumens of the catheter, wherein the proximal end portion of the catheter is skived and defines first and second selected lengths of two of the lumens, wherein the first and second selected lengths differ in length from each other,
• the hub passageways extend from respective ones of the interior openings to respective proximal openings within which distal end portions of the respective extension tubes are contained, a centermost of the passageways extends proximally and upwardly at a small angle from horizontal and outermost ones of the passageways extend proximally and laterally outwardly at respective small angles from a vertical medial plane through the hub body.
