Abstract

The invention provides a device and methods for analysing 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 method of analyzing subject fluids and providing substances to the subject fluids comprising the steps of:

(a) accessing a site through an elastic self closing diaphragm implanted in the skin of a living body;

(b) delivering a substance to the site via a feed element associated with the elastic self closing diaphragm; and

(c) analyzing the subject fluids via an aspiration element associated with the elastic self closing diaphragm.

2. The method of claim 1 further comprising the step of extracting the subject fluids via the aspiration element.

3. The method of claim 1 further comprising the step of inserting an analysis element via the aspiration element.

4. The method of claim 3 further comprising the substep of inserting the analysis element to a midpoint of the aspiration element.

5. The method of claim 3 further comprising the substep of inserting to a distal end of the aspiration element.

6. The method of claim 3 further comprising the substep of inserting the analysis element via the aspiration element into the site, the analysis element being disposed externally to the aspiration element.

7. The method of claim 3 wherein the analysis element is a sensor.

8. The method of claim 3 wherein the analysis element is a probe.
