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.
1. A body fluid sampling system for use on a tissue site, the system comprising: a housing;a controllable drive force generator with an electronic brake;a plurality of penetrating members operatively coupled to said controllable drive force generator, said controllable drive force generator moving e
1. A body fluid sampling system for use on a tissue site, the system comprising: a housing;a controllable drive force generator with an electronic brake;a plurality of penetrating members operatively coupled to said controllable drive force generator, said controllable drive force generator moving each of said members along a path out of a housing having a penetrating member exit into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;a processor coupled to the controllable drive force generator; providing for controlled velocity and a controlled depth of penetration of a penetrating member;a plurality of analyte detecting members in a sample chamber, each sample chamber configured to receive body fluid from a wound in tissue created by a penetrating member, and each analyte detecting member configured to determine at least one analyte level using a body fluid sample of less than about 1 microliter;a support member disc with a surface that includes said penetrating members, said support member disc being movable to move each of said penetrating members to a launch position associated with said force generator; andsaid controllable drive force generator and processor configured to provide a controllable velocity trajectory into the tissue and out of said tissue and controllable depth of penetration of a penetrating member, the processor modulating power to the controllable drive force generator through a signal generator so that a velocity profile of the penetrating member does not exceed a predetermined profile by more than a preset error limit. 2. The system of claim 1, further comprising a plurality of analyte detecting members positioned to receive body fluid. 3. The system of claim 1, wherein: the sample chamber has an opening for transport of a body fluid into the sample chamber, the sample chamber being sized to receive no more than 0.75 microliter of the body fluid. 4. The system of claim 1, wherein: the sample chamber has an opening for transport of a body fluid into the sample chamber, the sample chamber being sized to receive no more than 0.5 microliter of the body fluid. 5. The system of claim 1, wherein: the sample chamber has an opening for transport of a body fluid into the sample chamber, the sample chamber being sized to receive no more than 0.25 microliter of the body fluid. 6. The system of claim 1, wherein: the sample chamber has an opening for transport of a body fluid into the sample chamber, the sample chamber being sized to receive no more than 0.1 microliter of the body fluid. 7. The system of claim 1, wherein: the analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample that does not exceed a volume of 1 microliter of a body fluid disposed in the sample chamber. 8. The system of claim 1, wherein the analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample that does not exceed a volume of 0.75 microliter of a body fluid disposed in the sample chamber. 9. The system of claim 1, wherein the analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample that does not exceed a volume of 0.5 microliter of a body fluid disposed in the sample chamber. 10. The system of claim 1, wherein the analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample that does not exceed a volume of 0.25 microliter of a body fluid disposed in the sample chamber. 11. The system of claim 1, wherein the analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample that does not exceed a volume of 0.1 microliter of a body fluid disposed in the sample chamber. 12. The system of claim 1, wherein each of the penetrating members is an elongate member without molded attachments. 13. The system of claim 1, further comprising: wherein the penetrating member exit is configured to be positioned against the tissue when the penetrating member contacts the tissue. 14. The system of claim 1, further comprising a feedback loop coupled to the controllable drive force generator, wherein said feedback loop is configured to provide feedback to control the drive force generator.
