Abstract

A system and method is provided for applying an anti-pathogenic material to various surfaces of a medical device, wherein the method includes identifying various surfaces of the medical tests which include noncritical dimensions, and limiting the application of the anti-pathogenic material to those surfaces. Some aspects of the invention further include the application of an anti-pathogenic lubricant material to various parts or components of a medical device to reduce friction.

Claims

1. A catheter assembly, comprising:

a catheter adapter having a proximal opening, a distal end, and a fluid pathway extending therebetween, the distal end of the catheter adapter housing a catheter, wherein the catheter adapter includes a tapered portion, wherein an inner surface of the tapered portion tapers gradually toward the distal end;

a septum slidably disposed within the fluid pathway, the septum having an H-shaped cross-section forming a distal receptacle, a proximal receptacle, and a membrane that separates the distal receptacle from the proximal receptacle, wherein the distal receptacle includes an upper arm and a lower arm;

a septum actuator positioned within the distal receptacle, the septum actuator having a central lumen that extends towards the proximal end of the catheter adapter, the septum actuator having a probe configured to bias the septum into an open position by opening a pathway through the membrane of the septum to allow fluid to flow through the septum when the septum is advanced within the fluid pathway towards the distal end of the catheter adapter such that the fluid pathway flows through the central lumen of the septum actuator and through the septum when the probe biases the septum into the open position, wherein a distal end of the septum actuator includes a base, wherein the probe extends proximally from the base of the septum actuator, wherein an inner diameter of a portion of the central lumen that extends through the base is larger than an inner diameter of a portion of the fluid pathway extending through probe, wherein the base is fixedly secured to the tapered portion of the catheter adapter, wherein the upper arm and the lower arm are configured to contact the base to splay outwardly in response to the entire septum sliding distally into the open position;

wherein inserting an external device into the proximal opening of the catheter adapter slides the entire septum distally into the open position and wherein removing the external device allows the membrane to self-close to slide the entire septum proximally into a closed position wherein the upper and lower arms extend parallel to each other in the closed position.

2. The catheter assembly of claim 1, further comprising an anti-pathogenic material applied to the septum actuator at an interface surface between the septum actuator and the septum.

3. The catheter assembly of claim 2, wherein the anti-pathogenic material comprises a lubricant.

4. The catheter assembly of claim 1, wherein at least one of the catheter adapter, the septum, and the septum actuator further comprise a surface exposed to the fluid pathway.

5. The catheter assembly of claim 4, further comprising an anti-pathogenic material applied to the surface exposed to the fluid pathway.

6. The catheter assembly of claim 5, wherein the anti-pathogenic material comprises a lubricant.

7. The catheter assembly of claim 1, further comprising an anti-pathogenic material applied to an outer surface of the septum at an interface surface between the septum and an inner surface of the catheter adapter.

8. The catheter assembly of claim 7, wherein the anti-pathogenic material comprises a lubricant.

9. The catheter assembly of claim 8, wherein the lubricant is a silicon-based lubricant.

10. The catheter assembly of claim 2, wherein the anti-pathogenic material is rigid or semi-rigid.

11. The catheter assembly of claim 7, wherein the anti-pathogenic material is rigid or semi-rigid.

12. The catheter assembly of claim 2, further comprising an identifying color to indicate a specific type of the anti-pathogenic material.

13. The catheter assembly of claim 2, wherein the anti-pathogenic material is applied to the septum actuator at a desired thickness that is proportionate to a duration of effectiveness of the anti-pathogenic material on the interface surface.

14. The catheter assembly of claim 2, wherein the anti-pathogenic material is in communication with a portion of the fluid pathway.
