Abstract

A vascular access device may include a body and a layer of the body that communicates with a pathogenic environment to discourage adhesion of a pathogen to the layer and thus repress pathogenic activity. A method of repressing pathogenic activity in a vascular access device includes providing the device with a body, and coating the body with a layer that discourages adhesion of a pathogen to the layer.

Claims

1. A medical device, comprising:

a vascular access device including a body having a lumen;

a septum positioned within the lumen, the septum having a slit through which a separate extravascular device may be inserted into the vascular access device;

a layer disposed on a surface of the septum, wherein the layer communicates with a pathogenic environment and wherein the layer includes a radio frequency activated coating;

wherein the radio frequency activated coating is metallic and is disposed on the surface of the septum and responds to radio frequency energy by repressing pathogenic activity on the radio frequency activated coating.

2. The medical device of claim 1, wherein the radio frequency activated coating is further disposed on an interior surface of the lumen of the body.

3. The medical device of claim 2, wherein the radio frequency activated coating is further integrated with the interior surface of the lumen of the body.

4. The medical device of claim 2, wherein the radio frequency activated coating is further compounded with the interior surface of the lumen of the body.

5. The medical device of claim 1, wherein the radio frequency activated coating is subject to heating when exposed to a specific radio frequency.

6. The medical device of claim 1, further comprising a radio frequency generator configured to transmit radio frequency waves.

7. The medical device of claim 1, wherein a radio frequency generator is configured to transmit radio frequency waves of a specific radio frequency known to induce heating of the radio frequency activated coating.

8. A medical device, comprising:

means for accessing a vascular system of a patient, and

means for discouraging adhesion of a pathogen,

wherein the pathogen resides near the means for accessing a vascular system of a patient,

wherein the means for accessing a vascular system includes a body having a lumen and a split septum positioned within the lumen, through which a separate extravascular device may be inserted into the means for accessing a vascular system, having a layer disposed on a surface of a septum wherein the layer includes a radio frequency activated coating,

wherein the radio frequency activated coating is disposed on the surface of the septum, the radio frequency activated coating responding to radio frequency energy by repressing pathogenic activity on the radio frequency activated coating, and wherein the radio frequency activated coating is metallic.

9. A medical system, comprising:

a vascular access device including a body having a lumen;

a septum positioned within the lumen, the septum having a slit through which a separate extravascular device may be inserted into the vascular access device;

a radio frequency activated coating included in an interior surface of the lumen of the body, the radio frequency activated coating being metallic and being subject to heating when exposed to a specific radio frequency; and

a radio frequency generator configured to transmit radio frequency waves of the specific radio frequency.

10. The medical device of claim 9, wherein the radio frequency activated coating is further integrated with the interior surface of the lumen of the body.

11. The medical device of claim 9, wherein the radio frequency activated coating is further compounded with the interior surface of the lumen of the body.

12. The medical device of claim 9, wherein the radio frequency activated coating is further disposed on or within the septum.
