Abstract

The invention provides a device and methods for analyzing body fluids wherein the device is implanted in the body and provides for both the delivery of substances into the body and for the testing of body fluids.

Claims

1. A device for testing body fluids and introducing a medicament, the device comprising:

(a) a port body configured to be permanently implantable into a body, the port body comprising a selectively accessible exposed portion external to the body, wherein the selectively accessible exposed portion is a self closing diaphragm;

(b) an aspiration tube depending from the port body and in contact with a source of body fluids, the aspiration tube being configured to aspirate body fluids;

(c) a testing component removeably associated with the aspiration tube; and

(d) a feed tube depending from the port body, the feed tube being configured to introduce a medicament to the body.

2. The device of claim 1, further comprising a feed catheter positionable within the feed tube and through the selectively accessible exposed portion.

3. The device of claim 1, further comprising an aspirating catheter positionable within the aspiration tube and through the selectively accessible exposed portion, wherein the aspirating catheter is positionable such that the catheter is in contact with the body fluids.

4. The device of claim 1, wherein the testing component is an electronic test sensor.

5. The device of claim 1, wherein the testing component is a probe.

6. The device of claim 1, wherein the testing component is disposed within the aspiration tube.

7. The device of claim 6, wherein the testing component is disposed at an intermediate point within the aspiration tube.

8. The device of claim 1, wherein the testing component is associated with an external portion of the aspirating catheter such that the testing component is disposed within the body.

9. The device of claim 1, wherein the testing component is positioned at a location external to the body.

10. The device of claim 1, wherein the port body further comprises an anchoring section attached to the port body, wherein the anchoring section is configured to stabilize the port body.

11. The device of claim 10, wherein the anchoring section is configured to stabilize the port body in skin.

12. The device of claim 10, wherein the anchoring section is configured to stabilize the port body under skin.

13. The device of claim 1, wherein the aspiration tube is shorter in length than the feed tube.

14. A device for testing body fluids and introducing a medicament, the device comprising:

(a) a port body for being permanently implanted into a body, the port body comprising a self closing diaphragm external to the body;

(b) an aspiration tube depending from the port body and in contact with a source of body fluids, the aspiration tube being configured to aspirate body fluids;

(c) a testing component removeably disposed within the aspiration tube; and

(d) a feed tube depending from the port body, the feed tube being configured to introduce a medicament to the body;

(e) a feed catheter positioned within the feed tube and through the selectively accessible exposed portion; and

(f) an aspirating catheter positioned within the aspiration tube and through the selectively accessible exposed portion;

(g) wherein the testing component is disposed at an intermediate point within the aspiration tube.

15. The device of claim 14, wherein the testing component is an electronic sensor.
