Abstract:
1. A tissue penetrating device for sampling body fluid from a patient and for use with a penetrating member, the device comprising: an electrical driver coupled to provide force that moves said penetrating member along a path into the tissue; a sensing device for use in controlling motion of the penetrating member to penetrate the skin of the patient to a desired depth of penetration that is sufficient to create a wound from which blood flows from the wound and into an interior of the tissue penetrating device for blood analysis without flowing through the penetrating member for blood analysis with reduced patient discomfort from the creation of the wound; a controller electrically coupled to the electrical driver and configured to receive a signal from the sensing device to control the electrical driver and a motion of the penetrating member; an electronic feedback loop circuit in electrical communication with the sensing device, the electrical driver and the sensing device configured to control a motion of the penetrating member; and wherein the electrical driver is used to stop the penetrating member in the tissue.
