Abstract
These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that 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. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
