1. A body fluid sampling system for use on a tissue site, the system comprising:

  • a drive force generator a plurality of penetrating members operatively coupled to said force generator, said 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 each of a penetrating member at least partially positioned adjacent to an analyte sensor 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 sensor configured to determine analyte levels using a body fluid sample of less than about 1 microliter;

    a flexible support member coupling said penetrating members [to define a linear array], said support member being movable and configured to move each of said penetrating members to a launch position associated with said force generator. said drive force generator configured to be controlled to follow a predetermined velocity trajectory into the tissue and out of said tissue.
