1. A body fluid sampling system for use on a tissue site, the system comprising:
- a single drive force generator;
a plurality of penetrating members operatively coupled to said drive 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;
a plurality of cartridges, wherein each of said cartridges houses one of said penetrating members;
a flexible support member carrying said cartridges parallel to each other on its top to define a linear array, said support member being movable and configured to move a penetrating members in one of said cartridges to a launch position to be coupled to said drive force generator; and
a penetrating member sensor is positioned to monitor the penetrating member coupled to said drive force generator, the penetrating member sensor configured to provide information relative to a depth of penetration of the penetrating member through a skin surface and an indication of velocity of a penetrating member.

Abstract
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.
