A skin penetrating system includes a housing member and a penetrating member positioned in the housing member. An analyte detecting member is coupled to a sample chamber. The analyte detecting member is configured to determine a concentration of an analyte in a body fluid using a sample of less than 1 μL of a body fluid disposed in the sample chamber. A tip of the penetrating member is configured to extend through an opening of the sample chamber.
What is claimed is: 1. A skin penetrating system, comprising: a housing member; an electronic drive force generator; a plurality of penetrating members positioned in the housing member, each of a penetrating member being couplable to the drive force generator; a plurality of sample chambers, each s
What is claimed is: 1. A skin penetrating system, comprising: a housing member; an electronic drive force generator; a plurality of penetrating members positioned in the housing member, each of a penetrating member being couplable to the drive force generator; a plurality of sample chambers, each sample chamber including electrodes, having a volume no greater than 1 μL and an analyte sensor, each of a sample chamber being positioned to receive fluid from a wound created by a penetrating member, and determine a concentration of an analyte in a fluid using a sample of less than 1 μL of the fluid, wherein when the penetrating member is removed from the sample chamber, the electrodes remain in the sample chamber and the volume of the sample chamber is less than 1 μL wherein a tip of the penetrating member is configured to extend through an opening of a sample chamber, wherein each penetrating member of the plurality of penetrating members has a packing density of no more than 1.0 cm3/penetrating member; a single substrate that supports the plurality of penetrating members and the plurality of sample chambers, the single substrate being rotatably positioned in the housing to position each of a penetrating member in a launch position to penetrate a tissue site, and then rotate to a next position for a launch position of a next penetrating member; and a programmable processor operatively programmed with software that has control instructions for controlling the drive force generator, to keep a wound tract created by a penetrating member open for a sufficient time to provide for spontaneous flow of blood for sample capture into an associated sample chamber, the control instructions selected from at least one of, penetration depth of a penetrating member, velocity of a penetrating member, velocity of a penetrating member in or out of target tissue and a dwell time of a penetrating member in the target tissue. 2. The system of claim 1, further comprising: a penetrating member sensor coupled to the processor and the plurality of penetrating members, the penetrating member sensor configured to provide information relative to a depth of penetration of a penetrating member through a skin surface. 3. The system of claim 1, further comprising: a plurality of cartridges positioned in a disposable member, each of a cartridge including a penetrating member and a sample chamber, the plurality of cartridges positioned on the single substrate. 4. The system of claim 3, wherein each of a cartridge has an exit port, and upon launch each of an associated penetrating member exits from the exit port. 5. The system of claim 1, wherein each penetrating member of the plurality of penetrating members has a packing density of no more than 0.75 cm3/penetrating member. 6. The system of claim 1, wherein each penetrating member of the plurality of penetrating members has a packing density of no more than 0.5 cm3/penetrating member. 7. The system of claim 1, wherein each penetrating member of the plurality of penetrating members has a packing density of no more than 0.25 cm3/penetrating member. 8. The system of claim 1, wherein each penetrating member of the plurality of penetrating members has a packing density of no more than 0.1 cm3/penetrating member. 9. The system of claim 1, wherein each penetrating member of the plurality of penetrating members and each associated sample chamber of the plurality of sample chambers have a combined packing density of no more than 1.0 cm3. 10. The system of claim 1, wherein each penetrating member of the plurality of penetrating members and each associated sample chamber of the plurality of sample chambers have a combined packing density of no more than 0.75 cm3. 11. The system of claim 1, wherein each penetrating member of the plurality of penetrating members and each associated sample chamber of the plurality of sample chambers have a combined packing density of no more than 0.5 cm3. 12. The system of claim 1, wherein each penetrating member of the plurality of penetrating members and each associated sample chamber of the plurality of sample chambers have a combined packing density of no more than 0.25 cm3. 13. The system of claim 1, wherein each penetrating member of the plurality of penetrating members and each associated sample chamber of the plurality of sample chambers have a combined packing density of no more than 0.1 cm3. 14. The system of claim 1, wherein each penetrating member is an elongated member without molded attachments.
