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

  • a drive force generator;

    a penetrating member operatively coupled to said force generator, said force generator moving said member 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;

    said drive force generator configured to be controlled to follow a predetermined velocity trajectory into the tissue and out of said tissue;

    a disposable housing said penetrating member, said disposable having a first and a second seal formed at a distal end and a proximal end of said disposable respectively to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation; and

    a user interface coupled to a processor, wherein in response to an input at the user interface by a user the processor provides an input to the drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction.
