A hub (14) for a triple lumen catheter (12) especially for use with a catheter assembly (10) such as for hemodialysis. The hub (14) has a body (40) with one distal opening (58) for insertion thereinto of a proximal end portion (26) of the catheter (12), and three proximal openings (52, 54, 56) for insertion thereinto of distal end portions (74, 76, 78) of three extension tubes (16, 18, 20) each associated with one of the catheter's three lumens (30, 32, 34). The hub provides three passageways (68, 70, 72) extending from respective proximal openings to respective interior openings (60, 62, 64) in communication with the one distal opening (58), for establishing fluid communication between each extension tube (16, 18, 20) and its associated catheter lumen (30, 32, 34). Preferably, the hub is insert molded to respective end portions of the catheter (12) and the extension tubes (16, 18, 20). |
