Microprobe deviceprovides an analyte signal from biosensorto an external analyte meter indicating analyte presence in an analyte-containing bodily fluid of a subject (not shown).

Silicon microprobe with integrated biosensor

A silicon nitride cuvette window for a microsampling device and method of construction are provided. The sample to be analyzed is drawn into the cuvette of the microsampling device. The silicon nitride window permits optical measurements to be made on analytes contained within the cuvette.

Silicon nitride window for microsampling device and method of construction

A silicon penetration device with increased fracture toughness and method of fabrication thereof are provided. The method comprises strengthening silicon penetration devices by thermally growing a silicon oxide layer on the penetration device and then subsequently stripping the silicon oxide. The method also includes strengthening silicon penetration devices through the sputtering of thin film coatings on the silicon penetration devices.

Silicon penetration device with increased fracture toughness and method of fabrication

This invention provides for an integrated device having a lance and analytic device in a single disposable unit where the lance releases fluid from skin and the analytic device collects and analyzes the fluid without the user removing an instrument housing which holds the disposable unit. In addition to the device, this invention provides for methods of using and manufacturing the device.

Integrated lancing and analytic device

A system for separating plasma from whole blood comprises a blood separation device and a blood separation driver. The blood separation device includes a flexible tube having a needle and shield at one end and a filter member at the other end. The needle may be used to access blood in a conventional blood collection device. The separation driver applies a peristaltic force to the flexible tube of the blood separation device, thus drawing blood from the collection device through the tube and to the filter member. The driver also includes a frame having a collar and clamp mechanism for supporting the inlet end of the flexible tube, thus allowing use of the blood driver without directly exposing it to the blood. Plasma may be collected from the filter element. The present invention also provides blood dispensing systems and methods for dispensing whole and pre-filtered blood. Such blood dispensing systems comprise a blood dispensing device and a blood dispensing driver.

A minimally intrusive and less painful, self-use microsampling device and method for the measurement of glucose and other analytes in blood are provided. The device of the invention may have one or two optical windows for measuring the concentration of an absorbent reaction product or no windows if methods other than optical absorbance is used. The sampling chamber of the device can contain analytical reagents and other additives to facilitate the sampling and analytical steps. Also provided is a fabrication method for the microsampling device.
