A medical device is presented, which includes a fluid pathway and a septum slidably housed within the fluid pathway. The septum can be opened by a septum actuator disposed in a fixed position within the fluid pathway. In some examples, both the septum actuator and the septum have at least one surface exposed to the fluid pathway. An anti-pathogenic material can be applied to these surfaces.

1. A medical device, comprising: a fluid pathway;a septum slidably housed within the fluid pathway, the septum dividing the fluid pathway into a proximal fluid chamber and a distal fluid chamber; the septum configured to be advanced in a distal direction, to an activated position;a septum actuator disposed in a fixed position within the distal fluid chamber of the fluid pathway, the septum actuator extending proximally into the distal fluid chamber, the septum actuator having an outer wall and an inner wall, the inner wall forming a lumen in fluid communication with the fluid pathway;a ventilation channel comprising a groove in an inner surface of the medical device, and adjacent the septum; andan anti-pathogenic material applied to one or both of the inner and outer walls of the septum actuator, a portion of the anti-pathogenic material further applied to a surface of the ventilation channel, the portion of the anti-pathogenic material applied to the surface of the ventilation channel having a thickness less than that which would occlude the ventilation channel. 2. The device of claim 1, wherein a material of at least one of the device and the septum actuator comprises the anti-pathogenic material. 3. The device of claim 1, wherein the anti-pathogenic material comprises a lubricant. 4. The device of claim 1, wherein the anti-pathogenic material is rigid or semi-rigid. 5. The device of claim 1, wherein the anti-pathogenic material comprises an identifying color to indicate a specific type of the anti-pathogenic material. 6. The device of claim 1, wherein the medical device is a catheter assembly, the catheter assembly forming the fluid pathway between a proximal opening, and a distal end of the catheter assembly, the distal end housing a catheter; wherein the septum is configured to move in a distal direction to an activated position when a separate device is inserted into the proximal opening of the catheter assembly; wherein the septum actuator has a probe and a base, the probe being positioned adjacent to the septum, the base being coupled to the catheter assembly. 7. The device of claim 6, wherein the anti-pathogenic material is applied along the outer wall of the probe but not along the outer wall of the base, and wherein the base comprises critical dimensions configured to fixedly couple the septum actuator to the catheter assembly. 8. The device of claim 1, wherein the septum comprises an inner surface forming a portion of the fluid pathway when the septum is housed within the fluid pathway, the anti-pathogenic material being applied to the inner surface of the septum. 9. The device of claim 1, wherein the anti-pathogenic material comprises a first anti-pathogenic lubricant and a second rigid or semi-rigid anti-pathogenic material. 10. The device of claim 1, wherein the device comprises an inner wall that forms the fluid pathway, the anti-pathogenic material being applied to the inner wall of the device. 11. The device of claim 1, wherein the anti-pathogenic material is applied to at least a portion of the inner and outer walls by at least one of a mechanical bond, and a chemical bond. 12. The device of claim 6, wherein the septum has a tubular shape and a barrier member, the barrier member having a slit extending therethrough. 13. The device of claim 12, wherein the anti-pathogenic material is applied to the barrier member, but not to the slit. 14. The device of claim 6, wherein the septum actuator has barbs on a proximal end of the septum actuator. 15. The device of claim 1, wherein the medical device is an infusion therapy device that includes: a ventilation channel disposed between the septum and an inner surface of the infusion therapy device; andan anti-pathogenic material applied to a surface of the ventilation channel, the anti-pathogenic material applied to the surface of the ventilation channel having a thickness less than that which would occlude the ventilation channel. 16. A medical device comprising: a body having a distal opening, a proximal opening, and a lumen, forming a fluid pathway, extending between the distal and proximal openings, an inner wall of the lumen forming a narrowed portion at the distal opening;a slidable septum positioned in the lumen to divide the lumen into a distal chamber and a proximal chamber, the septum comprising an inner surface forming a portion of the fluid pathway when the septum is housed within the fluid pathway; the septum is configured to be advanced in a distal direction to an activated position,a septum actuator fixedly positioned in the lumen within the distal chamber, the septum actuator having a base at a distal end that inserts within the narrowed portion of the inner wall and extends proximally into the distal chamber, the septum actuator having an outer wall and an inner wall, the inner wall forming a lumen through which fluid can flow between the distal chamber and the distal opening;a ventilation channel comprising a groove in the inner wall of the body, and adjacent the septum; andan anti-pathogenic material applied to the inner surface of the septum and to one or both of the inner and outer walls of the septum actuator, a portion of the anti-pathogenic material further applied to a surface of the ventilation channel, the portion of the anti-pathogenic material applied to the surface of the ventilation channel having a thickness less than that which would occlude the ventilation channel. 17. A medical device comprising: a body having a distal opening, a proximal opening, and a lumen extending between the distal and proximal openings;a septum positioned in the lumen to divide the lumen into a distal chamber and a proximal chamber, the septum being configured to slide in a distal direction within the lumen; a septum actuator that is fixed within the distal chamber such that, when another device is inserted into the proximal opening of the body, the other device forces the septum distally into the septum actuator thereby causing a portion of the septum actuator to pierce the septum forming a fluid path for flow of a fluid through the septum actuator and the body; a ventilation channel comprising a groove in an inner surface of the body, and adjacent the septum; and an anti-pathogenic material applied to an inner surface and an outer surface of the septum actuator, a portion of the anti-pathogenic material further applied to a surface of the ventilation channel, the portion of the anti-pathogenic material applied to the surface of the ventilation channel having a thickness less than that which would occlude the ventilation channel. 18. The medical device of claim 17, wherein the septum actuator comprises a distal base that is coupled to the body and a proximal probe, the anti-pathogenic material being applied to an inner surface and an outer surface of the proximal probe. 19. The medical device of claim 17, wherein the septum has an H-shaped cross-section, the anti-pathogenic material being applied to one or more inner surfaces of the septum.
