Patent ID: 7713214

Claim:
A device for use with a penetrating member driver to penetrate tissue, the device comprising: a single disposable; an electronic drive force generator; a processor coupled to the electronic drive force generator, the processor having programmable control over a velocity vs. position profile of a lancing process including at least one of, timing the start of the penetrating member, tracking penetrating member position, measuring penetrating velocity, controlling a distal stop acceleration, and controlling a skin penetration depth; a plurality of penetrating members coupled to said single disposable and operatively couplable to the electronic drive force generator, said penetrating members movable to extend radially outward from the disposable to penetrate tissue, the electronic drive force generator and a penetrating member creating a wound tract that remains open for a sufficient time to permit a flow of a body fluid from a wound tract; a plurality of sample chambers in the single disposable, each of a sample chamber being associated with a penetrating member and including an aperture at an exterior surface of the single disposable configured to receive the body fluid from the wound tract; and a plurality of optical analyte sensors, each of an optical analyte sensor being positioned in a sample chamber to receive body fluid from the wound in the tissue created by the penetrating member, wherein each of a sample chamber has a clear portion to allow light to pass for optical sensing; and an optical illumination system to provide illumination of at least a portion of the sample chamber.
