Abstract
A catheter assembly (10) having a catheter (12) with lumens (20a,20b), extension tubes (14a,14b) and a hub (16). Distal ends (36) of the extension tubes and the proximal end (24) of the catheter are secured in and to the hub. Fittings (50) are first affixed in the distal ends of the extension tubes and have annular collars (56) that are embedded in the hub when the hub is molded over the distal ends of the extension tubes during manufacturing. An array of annular barbs (60) secure the cylindrical portion (52) of each fitting in the respective extension tube distal end (36).
Claims11
A catheter assembly comprising:
- a catheter having at least one lumen extending from a distal end to a proximal end;
- an extension tube associated with each at least one lumen and having a distal end and a proximal end;
- and
- a hub physically joining the catheter and each at least one extension tube and establishing fluid communication between each catheter lumen and a respective extension tube,
- wherein each extension tube distal end is secured to and within the hub by a fitting secured to the extension tube distal end, the fitting having a distal enlargement embedded in the hub.
A method of making a catheter assembly having a catheter with a proximal end and at least one lumen, an extension tube associated with each lumen of the catheter and having a distal end, and a hub joining the catheter proximal end to the distal end of each extension tube, comprising the steps of:
- providing a catheter having at least one lumen and a proximal end;
- providing an extension tube associated with each at least one catheter lumen and each having a distal end;
- inserting into and securing to the distal end of each extension tube, a fitting where the fitting has an enlargement at its distal end;
- and
- molding a hub about the proximal end of the catheter and the distal ends of the extension tubes,
- whereby the enlargement of each fitting is embedded and anchored in the hub securing the respective extension tube to the hub.
