Claim Text:
1. A method of removably coupling a catheter hub, comprising the steps of: a. providing a catheter hub comprising b. fixedly coupling a multi-lumen catheter to the core member; c. disposing the core member through the central mounting section of the proximal hub member such that the annular detent of the core member is distal from a distal end of the central mounting section and the o-ring interfaces with the longitudinal lumen of the sealing member; d. sliding the distal end of the multi-lumen catheter through the internal lumens of the sealing member and the distal hub member such that the hemostatic valve creates a fluid barrier between a distal end of the longitudinal lumen of the distal hub member and the annular shelf on the distal end of the sealing member; and e. translating the proximal hub member and the distal hub member towards each other such that the resilient projection enters the open distal end of the proximal hub member, deflects radially inwards, and returns to its original non-deflected state, thereby engaging with a distal interfacing surface of the catch opening and coupling removably the distal hub member and the proximal hub member; wherein the wall of the core member comprises a first annular taper formed at the distal end of the core member and a second annular taper intermediate the annular recess and a flange at a proximal end of the core member; the longitudinal lumen of the sealing member includes a narrow distal section, a wide proximal section, a tapering intermediate section, and a tapering proximal section; the first annular taper of the core member interfaces with the tapering proximal section of the sealing member, such that the o-ring interfaces with the surface of the longitudinal lumen of the sealing member and creates the fluid barrier between the longitudinal lumen of the sealing member and the first annular taper of the core member.
