A body fluid sampling system for use on a tissue site includes a drive force generator. A plurality of penetrating members are housed in a penetrating member housing. Each of penetrating member is configured to be coupled to the drive force generator. A plurality of analyte sensors are housed in an analyte sensor housing. Each analyte sensor is associated with a penetrating member. The analyte sensor housing is in a surrounding relationship to the penetrating member housing and positioned to provide that upon launch of a penetrating member, and penetration of a penetrating member at a skin surface, blood flows into the analyte sensor.
