A catheter connector for a subcutaneously placed catheter. The catheter connector can be configured for a single lumen catheter or a multiple lumen catheter. The connector facilitates precise positioning of both distal and proximal ends of a catheter, providing enhanced functionability and patient comfort.
1. A catheter connector, comprising: a stem including a first and second lumen extending longitudinally from a proximal end of the stem to a distal end of the stem, a first and second prong positioned at the distal end of the stem corresponding, respectively, to the first and second lumen, the first
1. A catheter connector, comprising: a stem including a first and second lumen extending longitudinally from a proximal end of the stem to a distal end of the stem, a first and second prong positioned at the distal end of the stem corresponding, respectively, to the first and second lumen, the first and second prong separated by a gap capable of receiving a catheter septum;a clamp coupled to the stem, the clamp including first and second clamp members separately hinged to a clamp base, the first and second clamp members including a recessed inner surface, the first and second prong having an outer profile generally corresponding to the recessed inner surface of the first and second clamp members; anda collar slidable from a proximal non-engaged position to a distal engaged position, the collar engaging an outer surface of each of the first and second clamp members in the distal engaged position. 2. The catheter connector according to claim 1, further comprising a first and second extension tube in fluid communication, respectively, with the stem first and second lumens. 3. The catheter connector according to claim 1, further comprising a patient attachment hub surrounding at least a portion of the stem. 4. The catheter connector according to claim 1, wherein a tip of each of the first and second prongs tapers distally from a larger diameter portion to a smaller diameter portion. 5. The catheter connector according to claim 1, wherein the stem further comprises a stop positioned proximal of the prong, the stop having a diameter greater than the diameter of a catheter outer wall. 6. The catheter connector according to claim 1, wherein the clamp includes a raised section around an outer wall thereof and the collar includes a recessed section on an inner wall thereof, and wherein movement of the recessed section over the raised section creates a locking engagement. 7. The catheter connector according to claim 1, wherein the clamp and the collar include mating thread portions to create a locking engagement. 8. The catheter connector according to claim 7, wherein the outer surface of the clamp includes threads, and the inner surface of the collar includes grooves. 9. The catheter connector according to claim 1, wherein the gap is tapered. 10. The catheter connector according to claim 1, wherein the clamp is separately formed and attached to the stem. 11. The catheter connector according to claim 1, wherein the first and/or the second clamp members include a latching mechanism. 12. The catheter connector according to claim 1, wherein the first and second prong include a shaft and a tip distal the shaft with an outside surface radially greater than the shaft and tapering toward a distal end. 13. The catheter connector according to claim 12, wherein the outer profile of the first and second prong corresponding to the recessed inner surface of the first and second members is along the tip of the first and second prong. 14. A method of connecting a dual lumen catheter to first and second extension tubes, comprising: providing a dual lumen catheter and the catheter connector according to claim 1;inserting the first and second prongs of the stem into, respectively, a first and second lumen of the catheter at the proximal end of the catheter;moving the first and second clamp members from a biased open position to a closed position over an outer surface of the catheter, the recessed inner surfaces of the first and second clamp members contacting the outer surface of the catheter; andsliding the collar from the proximal non-engaged position to the distal engaged position, thereby engaging the first and second clamp members. 15. The method according to claim 14, further comprising the step of pushing the catheter proximally until the proximal end contacts a stop positioned on the stem. 16. A catheter connector, comprising: a stem including a first and second lumen extending longitudinally from a proximal end of the stem to a distal end of the stem, a first and second prong positioned at the distal end of the stem corresponding, respectively, to the first and second lumen, the first and second prong separated by a gap capable of receiving a catheter septum;a clamp coupled to the stem, the clamp including first and second clamp members separately hinged to a clamp base, the first and second clamp members including a recessed inner surface, wherein the clamp base forms a ring sized to fit within a corresponding recessed section of the stem to prevent longitudinal movement of the clamp base relative to the stem; anda collar slidable from a proximal non-engaged position to a distal engaged position, the collar engaging an outer surface of each of the first and second clamp members in the distal engaged position. 17. The catheter connector according to claim 16, wherein the first and second clamp members are directly attached to the clamp base by a living hinge with a circumferential profile less than the first and second clamp members. 18. A catheter connector, comprising: a stem including a first and second lumen extending longitudinally from a proximal end of the stem to a distal end of the stem, a first and second prong positioned at the distal end of the stem corresponding, respectively, to the first and second lumen, the first and second prong separated by a gap capable of receiving a catheter septum;a clamp coupled to the stem, the clamp including first and second clamp members separately hinged to a clamp base, the first and second clamp members including a recessed inner surface, wherein the recessed inner surface of each of the first and second clamp members is configured to contact an outer surface of a catheter in a closed position to clamp the catheter to the stem by compressing a portion of the catheter against the first and second prong; anda collar slidable from a proximal non-engaged position to a distal engaged position, the collar engaging an outer surface of each of the first and second clamp members in the distal engaged position.
