Abstract

Embodiments of this disclosure include systems, methods, and kits for sterilizing in vivo catheters using an optical fiber to deliver UV light. In an embodiment, a method for sterilizing a catheter with at least a first lumen, includes inserting a distal end of a fiber optic cable into a fiber insertion port of a catheter connector attached to a hub of the first lumen, flushing the first lumen with fluid from a fluid source, inserting the fiber optic cable into the first lumen until a stopper of the fiber optic cable is adjacent to the fiber insertion port, providing light to the fiber optic cable from a light source after the fiber optic cable is inserted into the first lumen, withdrawing the fiber optic cable from the first lumen while the light is provided, and ceasing to provide light to the fiber optic cable after the fiber optic cable is withdrawn from the first lumen. The disclosure is also applicable to catheters with multiple lumens and to catheters accessed through subcutaneous ports.

Claims (49)

1. A kit for sterilizing a catheter of at least one designated catheter type with at least

a first lumen, comprising:

a first fiber optic cable with a first fiber optic connector;

a first catheter connector, including

a first fiber insertion port configured to receive the first fiber optic cable, and

a first hub adapter configured to connect with a first hub of the first lumen of the catheter at a proximal end of the first lumen;

a first stopper; and

packaging containing the first fiber optic cable, the first catheter connector, and the first stopper,

wherein

the first stopper is attached to or integrally formed with the first fiber optic cable at a first fiber length from a first distal end of the first fiber optic cable, and

the first fiber length corresponds to a combined length of a first lumen length of the first lumen from the first hub to a first lumen distal end of the first lumen and a first catheter connector length of the first catheter connector from the first fiber insertion port to the first hub adapter.

2. The kit of claim 1 , wherein the first fiber length corresponds to the combined length by being shorter than, but within 6 cm of, a sum of the first lumen length and the first catheter connector length less an overlap connection length of the first hub adapter and the first hub.

3. The kit of claim 1 , further comprising a label including information about the at least one designated catheter type.

4. The kit of claim 1 , wherein the packaging is sterile packaging and contents of the packaging are sterile.

5. The kit of claim 1 , wherein the first catheter connector is a hemostasis valve and the first fiber insertion port includes a one-way valve.

6. The kit of claim 1 , further comprising a syringe filled with a flushing fluid.

7. The kit of claim 1 , wherein the first stopper is at least one of a torque device, a hinged device, a clamping apparatus, and a bead comprising at least one of silica, plastic, resin, or epoxy.

8. The kit of claim 1 , wherein the first fiber length is between 25 cm and 80 cm.

9. The kit of claim 1 , further comprising an empty syringe or other suction device.

10. The kit of claim 1 , further comprising:

a second fiber optic cable with a second fiber optic connector;

a second catheter connector, including

a second fiber insertion port configured to receive the second fiber optic cable, and

a second hub adapter configured to connect with a second hub of a second lumen of the catheter at a proximal end of the second lumen;

a second stopper,

wherein:

the packaging further contains the second fiber optic cable, the second catheter connector, and the second stopper and

the second stopper is attached to or integrally formed with the second fiber optic cable at a second fiber length from a second distal end of the second fiber optic cable.

11. The kit of claim 10 , wherein the first fiber length is longer than the second fiber length.

12. The kit of claim 11 , wherein:

at least one of the first fiber optic connector, the first stopper, and a marking or flag on the first fiber optic cable is colored blue, and

at least one of the second fiber optic connector, the second stopper, and a marking or flag on the second fiber optic cable is colored red.

13. The kit of claim 10 , wherein the first fiber length corresponds to the combined length by being shorter than, but within 6 cm of, a sum of the first lumen length and the first catheter connector length less an overlap connection length of the first hub adapter and the first hub.

14. The kit of claim 10 , further comprising a label including information about the at least one designated catheter type.

15. The kit of claim 10 , wherein the packaging is sterile packaging and contents of the packaging are sterile.

16. The kit of claim 10 , wherein the first catheter connector is a hemostasis valve and the first fiber insertion port includes a one-way valve.

17. The kit of claim 10 , further comprising a syringe filled with a flushing fluid.

18. The kit of claim 10 , wherein the first stopper is at least one of a torque device, a hinged device, a clamping apparatus, and a bead comprising at least one of silica, plastic, resin, or epoxy.

19. A kit for sterilizing a catheter of at least one designated catheter type with at least a first lumen, comprising:

a first fiber optic cable with a first fiber optic connector;

a first catheter connector, including

a first fiber insertion port configured to receive the first fiber optic cable, and

a first hub adapter configured to connect with a first hub of the first lumen of the catheter at a proximal end of the first lumen;

a first stopper; and

packaging containing the first fiber optic cable, the first catheter connector, and the first stopper,

wherein

the first fiber optic cable includes at least a first stopper marking at a first fiber length from a first distal end of the first fiber optic cable, and

the first fiber length corresponds to a combined length of a first lumen length of the first lumen from the first hub to a first lumen distal end of the first lumen and a first catheter connector length of the first catheter connector from the first fiber insertion port to the first hub adapter.

20. The kit of claim 19 , wherein the first fiber length is between 25 cm and 80 cm.
