Abstract
A device is provided for use with a body fluid sampling device for extracting bodily fluid from an anatomical feature. The device comprises a cartridge having a plurality of cavities. The device may include a plurality of penetrating members each at least partially contained in the cavities of the cartridge wherein the penetrating members are slidably movable to extend outward from openings on the cartridge to penetrate tissue. The device may also include a plurality of analyte detecting members and a plurality of chambers. Each chamber may be associated with one of the cavities, the chambers positioned along an outer periphery of the cartridge, wherein at least one of said analyte detecting members forms a portion of one wall of one of said plurality of chambers. In one embodiment, the device may also include a fluid spreader positioned over at least a portion of said analyte detecting member to urge fluid toward one of the detecting members.
