A catheter connection system and a method of connecting the catheter connection system to a catheter. The catheter connection system includes a hub assembly and a collar. The hub assembly includes a cannula extending from a distal end thereof, and a collet defining an inner surface spaced apart from the cannula to permit passage of a catheter wall between the body and the cannula.
1. A catheter connection system, comprising: a cannula in fluid communication with a tube;a collet having a length surrounding the cannula with an inner surface spaced from an outer surface of the cannula to permit passage of a catheter wall therebetween, the collet including a proximal barb on an o
1. A catheter connection system, comprising: a cannula in fluid communication with a tube;a collet having a length surrounding the cannula with an inner surface spaced from an outer surface of the cannula to permit passage of a catheter wall therebetween, the collet including a proximal barb on an outer surface thereof; anda collar including a compression ring incorporated into a distal section thereof and a proximal attachment barb engaging the collet proximal barb to secure the collar to the collet, the collar freely rotatable over the collet following engagement. 2. The catheter connection system according to claim 1, further comprising a core member surrounding a proximal end of the cannula. 3. The catheter connection system according to claim 1, wherein the cannula comprises a first cannula member and a second cannula member to be received, respectively, in a first lumen and a second lumen of a multi-lumen catheter. 4. The catheter connection system according to claim 3, further comprising a bifurcation molded over a proximal end of a core member and the tube, the tube comprising a first extension tube in fluid communication with the first cannula and a second extension tube in fluid communication with the second cannula. 5. The catheter connection system according to claim 3, wherein the first and second cannula members are slightly larger than the first and second lumens such that a compressive fit is formed when the cannula members are slid into the lumens. 6. The catheter connection system according to claim 1, wherein the collet outer surface further comprises one or more threads. 7. The catheter connection system according to claim 6, wherein an inner surface of the collar comprises one or more threads that interact with the collet threads. 8. The catheter connection system according to claim 7, wherein the collet threads are spaced apart from the collar threads following engagement of the collet proximal barb and the collar proximal attachment barb. 9. The catheter connection system according to claim 1, wherein the collet outer surface includes a tapered distal section. 10. The catheter connection system according to claim 1, wherein the collet inner surface includes a plurality of ridges.
