摘要： The invention provides methods and apparatus for detecting an analyte in blood. The apparatus is particularly suited for bringing a sensor into direct contact with blood in vivo. The apparatus comprises a sensor that detects the presence of an analyte and an assembly means. The assembly means has a sensor end, wherein the sensor end of the assembly means is affixed to the sensor, and the assembly means is adapted for coupling with a venous flow device. By coupling with a venous flow device, the assembly means brings the sensor into direct contact with blood flowing through the venous flow device. Examples of venous flow devices that bring the sensor into direct contact with the blood of a subject include, but are not limited to, intravenous catheters and external blood loops, such as are used in extra corporeal membrane oxygenation or hemodialysis.

摘要： A method and apparatus for enhancing the integrity of an implantable sensor. Voids formed between an outer tubing and a sensor substrate or spacing element may be back-filled with a curable, implantable material, minimizing the extent to which unwanted fluids diffuse within the sensor. An enzyme or protein matrix pellet below the sensor window may be pre-treated with a reducing agent to enhance its bond stability, and to reduce undesired swelling that may cause the sensor window to detach or leak. The bonding between the enzyme pellet and a hydrogel layer may be reinforced by application of an intervening bonding layer of a protein material, such as human serum albumin (HSA). The size of the window may be minimized by minimizing the size of an underlying electrode, providing reduced flux and lengthening sensor. A coating may be deposited on the surface of the sensor leads, providing stiffening and lubrication.

摘要： A system and method for calibrating a sensor. The method may include, without limitation, compiling an array of data relating to the sensor; adjusting a sensor parameter a first time based on data in the array; adjusting a curve representing the sensor output based on data in the array; and adjusting the sensor parameter a second time based on data in the array. The sensor may be an in vivo glucose sensor and the sensor parameter adjusted may be a current. The array may include historical as well as recent data, such as, for example, blood glucose readings and sensor electrode readings.

摘要： A sensing apparatus with a connector, a sensor lead and a sensor module with a spacer placed over electrodes that have been deposited on a substrate. The spacer may have a space for receiving an enzyme. End portions of the sensor module may be encapsulated, such as with molded beads. A sensor lead may attach to the sensor module and may have an outer tubing that passes over the module and attaches to the beads at the end of the sensor module. The sensor lead may also attach to the connector such that the sensing apparatus may be electrically coupled to a pump, electronics or other devices. The sensing apparatus may be implanted into a vein or artery.
