Abstract: A single or multilumen intravenous catheter that may include an integral biosensor having an active portion exposed through a sensing port formed in a distal portion of an outer wall of the catheter. The biosensor may be formed on a flex circuit mounted to a support member or probe that displaces the active portion from an inner wall of the catheter for protection from friction during installation through a lumen. The support member or probe may position the biosensor concentrically within the lumen or against an inner diameter of the outer wall. The biosensor may be sealed about the sensing port to prevent passage of fluid therethrough, or a proximal end of the sensing port may remain open to allow flushing of the biosensor with saline infused through the lumen.

Abstract: The present invention is directed to a sensing element that comprises a flexible substrate having first and second opposite surfaces; at least one sensor disposed on the first surface of the flexible substrate; an adhesive layer substantially covering the second surface of the flexible substrate; and a release liner releasably adhered to the adhesive layer so that upon removal of the release liner the adhesive layer is exposed for securing the sensing element to the catheter. The release liner permits the sensing element to be positioned at a desired location within the catheter after which the release liner can be removed to expose the adhesive layer. The adhesive layer can then be used to attach and secure the sensing element at a desired location on the catheter. As a result, the need for additional adhesives can be reduced or eliminated.

Abstract: A flux limiting layer for an intravenous amperometric biosensor is formed on a substrate to limit a diffusion rate of an analyte from blood to an enzyme electrode. The layer may be formed from ethylene vinylacetate (EVA) dissolved in a solvent such as paraxylene, spray-coated to cover a portion of the electrode, and cured to seal the electrode to the substrate. In a glucose sensor having glucose oxidase disposed on the electrode, thickness and concentration of the EVA layer are optimized to promote a linear output of electrode current as a function of blood glucose concentration.
