## 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

### Claim 1

A catheter assembly, comprising:
a catheter adapter having a proximal opening, a distal end, and a fluid pathway extending therebetween, a distal end of the catheter adapter housing a catheter;
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 membrane comprises a slit;
a septum actuator fixedly positioned within the distal receptacle, the septum actuator having a central lumen that extends towards the proximal opening of the catheter adapter, the septum actuator having a probe surface configured to bias the septum into an open position by opening 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 flows through the central lumen of the septum actuator when the probe surface biases the septum into the open position, wherein an outer diameter of the probe surface is larger than an inner diameter of the distal receptacle such that a fluid tight seal is provided between the probe surface and the septum, wherein the inner diameter of the distal receptacle is constant from the membrane to a distal end of the distal receptacle.

### Claim 2 (depends on 1)

The catheter assembly of claim 1, wherein the septum actuator further comprises a first end comprising a wedge, wherein a second end comprises the probe surface, wherein the septum actuator further comprises a lumen extending between the first end and the second end, the first end being inserted into a base of the catheter to couple the base of the catheter to the distal end of the catheter adapter, the probe surface being positioned within the distal receptacle.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 3)

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

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 8)

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

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 3)

The catheter assembly of claim 3, wherein the anti-pathogenic material is rigid or semi-rigid.

### Claim 12 (depends on 8)

The catheter assembly of claim 8, wherein the anti-pathogenic material is rigid or semi-rigid.

### Claim 13 (depends on 3)

The catheter assembly of claim 3, further comprising an identifying color to indicate a specific type of the anti-pathogenic material.

### Claim 14 (depends on 3)

The catheter assembly of claim 3, 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.

### Claim 15 (depends on 3)

The catheter assembly of claim 3, wherein the anti-pathogenic material is in communication with a portion of the fluid pathway.

### Claim 16 (depends on 2)

The catheter assembly of claim 2, further comprising:
a first anti-pathogenic material interposedly positioned between the septum actuator and the septum;
a second anti-pathogenic material applied to the lumen of the septum actuator;
a third anti-pathogenic material applied to a surface of the septum; and
a fourth anti-pathogenic material interposedly positioned between the septum and an inner surface of the catheter adapter.

### Claim 17 (depends on 16)

The catheter assembly of claim 16, wherein the first and fourth anti-pathogenic materials comprise a lubricant.

### Claim 18 (depends on 16)

The catheter assembly of claim 16, wherein the second and third anti-pathogenic materials are rigid or semi-rigid.
