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

  • an electrically powered drive force generator;

    an injection penetrating member operatively coupled to said electrically powered drive force generator, said electrically powered drive force generator moving said injection penetrating member along a path out of a housing having the injection penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;

    a disposable housing said injection penetrating member, said disposable couple to a first and a second seal 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 electrically powered drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction and an amount of fluid injected.
