Method for detecting an analyte in blood
First Claim
1. A method of detecting an analyte in a tissue of a subject comprising contacting the tissue of the subject with an apparatus comprising:
- an elongated conductive material having a protrudent end, the protrudent end comprising a sensor that detects the presence of an analyte, wherein the sensor comprises a plurality of layers including;
a base layer;
a plurality of electrodes disposed on the base layer;
an analyte sensing layer disposed upon the electrode;
an analyte modulating layer disposed on the analyte sensing layer; and
a support having a proximal end and a distal end;
wherein the conductive material is positioned on the support and the protrudent end of the conductive material comprising the sensor that detects the presence of an analyte;
(a) protrudes beyond the distal end of the support; and
(b) is positioned on the support in combination with a venous flow device and assembly means, wherein the sensor is affixed to a sensor end of the assembly means and the assembly means is adapted for coupling with the venous flow device.

Abstract
The methods and apparatus for detecting an analyte in blood are useful for detecting an analyte in tissue of a subject. The apparatus comprises a sensor, which comprises an elongated conductive material having a protrudent end, the protrudent end comprising an electrode that detects the presence of an analyte; a substrate affixed to the conductive material; and a support having an external surface, a proximal end, and a distal end. The conductive material is positioned on the support and the protrudent end of the conductive material protrudes beyond the distal end of the support. Optionally, the sensor is suspended within the lumen of a venous flow device. Typically, only a portion of the sensor is suspended within the lumen of the venous flow device, said portion comprising the protrudent end of the conductive material. Alternatively, the conductive material is positioned on the external surface of the intravenous infusion catheter.
