Abstract

Ports, such as the ports of ported catheters or of female luer fittings, can be configured to include an antimicrobial septum for disinfecting devices that are attached to the ports. The antimicrobial septum can be positioned within the lumen of the port. The lumen can include an annular recess for securing the antimicrobial septum in place during use. The antimicrobial septum can include an antimicrobial lubricant which transfers onto a device, such as a male luer, as the device passes through the septum thereby killing any microbes that may be present on the surfaces of the device. The antimicrobial septum can be configured in various shapes including a continuous disk shape, a ring shape, or an elongated ring or tube shape. When configured as a ring or tube shape, the inner surfaces of the antimicrobial septum may contain slits or grooves. The slits or grooves can facilitate the compression of the septum as a device passes through it, while also increasing the surface area of the septum on which antimicrobial lubricant can be contained.

First claim

The invention claimed is:

1. An intravascular device, comprising:
a port, comprising:
a lumen, the lumen comprising an annular recess;
an antimicrobial septum positioned within the annular recess, wherein the antimicrobial septum comprises a ring, wherein the ring comprises:
a generally circular outer surface,
a generally circular inner surfaced,
a top surface;
a bottom surface; and
a plurality of slits or a plurality of grooves, wherein the generally circular inner surface forms an opening of the ring that extends from the top surface through the bottom surface, wherein each of the plurality of slits or each of the plurality of grooves extends from the top surface through the bottom surface and partially from the generally circular inner surface to the generally circular outer surface, wherein an antimicrobial lubricant is applied to the circular inner surface and each of the plurality of slits or each of the plurality of grooves, wherein the antimicrobial lubricant provides antimicrobial protection to another device when the other device is inserted into the lumen and into the antimicrobial septum; and

another septum secured with respect to the lumen, wherein the other septum contacts the lumen and forms a fluid-tight seal across the lumen, wherein the antimicrobial septum and the other septum are spaced apart.

2. The intravascular device of claim 1 , wherein the antimicrobial lubricant is applied to the inner surface of the ring.

3. The intravascular device of claim 1 , wherein the port comprises a female luer.

4. The intravascular device of claim 3 , wherein the other device comprises a male luer and wherein the annular recess is positioned such that when the other device is connected to the port the male luer extends partially into the antimicrobial septum.

5. The intravascular device of claim 1 , wherein the intravascular device is a ported catheter or a female luer fitting.

6. The intravascular device of claim 1 , wherein the generally circular outer surface is positioned within the annular recess.

7. The intravascular device of claim 1 , wherein each of the plurality of slits extends from the inner surface towards the generally circular outer surface.

8. A ported catheter, comprising:
a catheter adapter;
a port extending from the catheter adapter, wherein the port comprises:
a lumen that an annular recess; and
an antimicrobial septum positioned within the annular recess, wherein the antimicrobial septum comprises a ring, wherein the ring comprises:
a generally circular inner surface;
a generally circular outer surface;
a top surface extending between the generally circular outer surface and the generally circular inner surface, and a bottom surface extending between the generally circular outer surface and the generally circular inner surface; and
a plurality of grooves formed on the generally circular inner surface, wherein the generally circular inner surface forms an opening of the ring that extends from the top surface through the bottom surface, wherein each of the plurality of grooves extends from the top surface through the bottom surface, wherein the plurality of grooves contains an antimicrobial lubricant that is transferred to a device when the device is connected to the port.

9. The ported catheter of claim 8 , further comprising:
a second septum for maintaining a fluid within the lumen of the port, wherein the second septum contacts the lumen and forms a fluid-tight seal across the lumen, wherein the antimicrobial septum and the second septum are spaced apart.

10. The ported catheter of claim 8 , wherein the generally circular outer surface is positioned within the annular recess.
