A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

Method and Apparatus for Penetrating tissue

A tissue penetration device and method of using same. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. An embodiment provides control of a lancet used for sampling blood. Electric field coils or solenoids may drive the lancet using electromagnetic force. Advancement and retraction of a lancet may be controlled by a feedback loop monitoring the position and velocity of the lancet embodiments of the lancet driver can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet and method for using a lancet to maintain the patency of the wound tract once the lancet has cut into the skin.

Tissue penetration device

A body fluid sampling system is provided for use on a tissue site. In one embodiment, the system comprises a cartridge; a penetrating member driver; a plurality of penetrating members arranged in a radial configuration on the cartridge wherein sharpened distal tips of the penetrating members point radially outward; wherein an active one of the penetrating members may be operatively coupled to the penetrating member driver, the penetrating member driver moving the active one along a path out of a housing having a penetrating member exit, into the tissue site, stopping in the tissue site, and withdrawing out of the tissue site; and a plurality of analyte detecting members, wherein at least one of the analyte detecting members is positioned to receive fluid from a wound created by the active one of the penetrating members, wherein the detecting members are not pierced by the active one of the penetrating members.

Method and apparatus for body fluid sampling and analyte sensing

The present invention provides methods, devices, and systems for wireless physiological sensor patches and systems which incorporate these patches. The systems and methods utilize a structure where the processing is distributed asymmetrically on the two or more types of ASIC chips that are designed to work together. The invention also relates to systems comprising two or more ASIC chips designed for use in physiological sensing wherein the ASIC chips are designed to work together to achieve high wireless link reliability/security, low power dissipation, compactness, low cost and support a variety of sensors for sensing various physiological parameters.

Verification device for optical clinical assay systems

Meter with integrated database and simplified telemedicine capability

The present invention provides improved systems and methods for verifying accurate test performance of monitoring systems, particularly for point-of-care service. Such monitoring systems typically include a test element containing the test reagent(s), and an electronic analyzer device. A blood or other patient sample is applied to the test element, which is introduced to the analyzer. As the reaction proceeds, the analyzer stores the data and outputs the testing result. Accuracy in the result is dependent upon proper functioning of both the test element and the analyzer. The systems of the present invention provide indicators to evaluate the integrity of the test elements and a verification device to evaluate the performance of the analyzer. Such systems may be provided as kits with instructions for use.
