Abstract

A catheter connector system for a subcutaneously placed catheter. The catheter connector system permits proximal trimming of the placed catheter, which is a procedure that provides numerous advantages over traditional methods of trimming catheter distal ends prior to implantation. The catheter connector system can be configured for a single lumen catheter or a multiple lumen catheter. The catheter connector system facilitates precise positioning of both distal and proximal ends of a catheter, providing enhanced function ability and patient comfort.

Claims

1. A catheter connector system for a catheter, comprising:

a boot comprising a tapered outer wall having a diameter that decreases toward a distal end thereof, said outer wall enclosing a longitudinally extending lumen, wherein said boot lumen is sized to prevent axial movement of said catheter when said catheter is positioned therein; and

a bifurcation assembly, comprising at least one extension leg extending from a proximal end thereof and at least one stem extending from a distal end thereof, wherein said at least one stem is configured to be received into a lumen of said catheter.

2. The catheter connector system according to claim 1, wherein said boot further comprises a pair of suture wings laterally extending from said outer wall.

3. The catheter connector system according to claim 1, wherein said boot and said bifurcation assembly further comprise coupling sections configured for locking connection to one another.

4. The catheter connector system according to claim 3, wherein said locking connection is permanent.

5. The catheter connector system according to claim 3, wherein said coupling sections are detachable from one another after said locking connection has been established.

6. The catheter connector system according to claim 3, wherein an audible confirmation is provided upon establishment of said locking connection.

7. The catheter connector system according to claim 3, wherein a tactile confirmation is provided upon establishment of said locking connection.

8. The catheter connector system according to claim 3, wherein said boot coupling section comprises a barbed end positioned on a proximal end of said boot, and wherein said bifurcation assembly coupling section comprises a hood positioned on a distal end of said bifurcation assembly surrounding said at least one stem.

9. The catheter connector system according to claim 8, wherein said hood is configured to provide a snap fit with said barbed end.

10. The catheter connector system according to claim 1, wherein said bifurcation assembly comprises a first and second extension leg in fluid communication with a first and second stem.

11. The catheter connector system according to claim 10, wherein said first and second stems are formed of metal.

12. The catheter connector system according to claim 10, wherein said first and second stems have a cross-sectional configuration matching that of a first and second lumen of said catheter.

13. The catheter connector system according to claim 1, wherein said boot is comprised of a soft elastomeric material.

14. The catheter connector system according to claim 13, wherein said material is comprised of either silicone or polyurethane.

15. The catheter connector system according to claim 1, wherein said boot lumen has a diameter smaller than the diameter of an outer wall of said catheter.

16. The catheter connector system according to claim 15, wherein said boot lumen diameter is in the range of approximately 0.50 mm to 4.0 mm and wherein said catheter outer wall diameter is in the range of approximately 0.55 mm to 4.4 mm.

17. A catheter connector system for an implanted catheter, comprising:

a boot comprising a tapered outer wall, having a diameter that decreases toward a distal end thereof and enclosing a longitudinally extending lumen, and a first connector member positioned at a proximal end thereof;

a bifurcation assembly, comprising at least one extension leg extending from a proximal end thereof and a second connector member positioned at a distal end thereof, said second connector member having at least one stem extending therefrom, said stem being configured to be received into a lumen of said catheter; and

a clamp configured to lock around said first and second connector members.

18. The catheter connector system according to claim 17, wherein said first connector member comprises a proximal portion that produces a compressive force on said catheter upon locking of said clamp therearound.

19. The catheter connector system according to claim 17, wherein said first connector member proximal portion is made of silicone having a durometer equal to approximately 30.

20. The catheter connector system according to claim 17, wherein said clamp further comprises a pair of suture wings.

21. The catheter connector system according to claim 17, wherein said clamp further comprises opposed halves that are connected together in a hinged arrangement.

22. The catheter connector system according to claim 21, wherein said opposed halves comprise interlocking teeth.

23. The catheter connector system according to claim 21, wherein said opposed halves comprise compression rings.

24. The catheter connector system according to claim 17, wherein said bifurcation assembly comprises a first and second extension leg in fluid communication with a first and second stem.

25. The catheter connector system according to claim 24, wherein said first and second stems are formed of metal.

26. The catheter connector system according to claim 24, wherein said first and second stems have a cross-sectional configuration matching that of a first and second lumen of said catheter.

27. The catheter connector system according to claim 17, wherein said first and second connector members are attachable to one another.

28. The catheter connector system according to claim 27, wherein said second connector member comprises a bore and said first connector member comprises a proximal portion that is receivable within said bore.

29. The catheter connector system according to claim 28, wherein said first connector member proximal portion has a frustoconical shape.

30. The catheter connector system according to claim 29, wherein said first connector member proximal portion comprises sectioned panels connected to a base.
