In one aspect, a body fluid sampling device is provided using a penetrating member to extract fluid from an anatomical feature. The device comprises a penetrating member actuator for moving the penetrating member inbound towards the anatomical feature and a non-spring based, penetrating member retractor for moving the penetrating member outbound away from the anatomical feature. The penetrating member actuator may be adapted to move the penetrating member at a velocity greater than a velocity achieved by the penetrating member retractor.

A body fluid sampling device using a penetrating member to extract fluid from an anatomical feature, said device comprising: a plurality of penetrating members;a penetrating member driver for moving each of the plurality of penetrating members inbound towards the anatomical feature;a single steri
1. A body fluid sampling device using a penetrating member to extract fluid from an anatomical feature, said device comprising: a plurality of penetrating members;a penetrating member driver for moving each of the plurality of penetrating members inbound towards the anatomical feature;a single sterility barrier that disposes over the plurality of penetrating members and is configured to maintain the plurality of penetrating members each in a sterile environment prior to launch of one of the plurality of penetrating members to the anatomical feature, the sterility barrier being in a non-contact relationship relative to a tip of each of the plurality of penetrating members;a mechanical sterility barrier removal device configured to breach the sterility barrier and to open the sterile environment to provide that each of the plurality of penetrating members does not pierce any materials when a penetrating member is actuated toward a tissue site;a user interface coupled to a processor with the processor being coupled to the penetrating member driver, wherein the processor is configured to provide the user interface with an option selected from at least one of, depth of a penetrating member penetration, velocity of a penetrating member, a desired velocity profile, a velocity of a penetrating member into the tissue site, velocity of the penetrating member out of the tissue site, dwell time of the penetrating member in the tissue site, and a target tissue profile,wherein said penetrating member driver in communication with the processor is configured to advance said penetrating member at an advancement velocity greater into the tissue site of the anatomical feature than a retraction velocity out of the tissue site of the anatomical feature with a dwell time sufficient to allow for a spontaneous flow of blood from the tissue site. 2. The device of claim 1 wherein the penetrating member driver uses a spring to move said penetrating member. 3. The device of claim 1 wherein the penetrating member driver uses one of the following to move said penetrating member: a motor and gear box, a nanomuscle, a pneumatic device, a liquid magnetic coil actuation, a stepper motor, a micro-clutch device, and an inductive motor. 4. The device of claim 1 further comprising the plurality of penetrating members arranged in a radial configuration. 5. The device of claim 1 further comprising the plurality of penetrating members arranged in a radial configuration on a disc, with distal tips of said penetrating members pointed radially outward. 6. The device of claim 1 wherein said penetrating member driver includes a gripper block shaped to extend into a disposable containing said penetrating member in order to engage said penetrating member. 7. The device of claim 1 wherein said penetrating member driver includes a portion for breaking a seal on a disposable containing said penetrating members, said portion breaking said seal to allow the driver to engage the penetrating member. 8. The device of claim 1 further comprising at least one guide bearing in said disposable for providing support in at least one of the following: lateral guidance or vertical guidance. 9. The device of claim 1 further comprising a slidable cutter for removing a seal on a disposable prior to penetrating member actuation. 10. The device of claim 1 further comprising a damper coupled to a coupler attaching the penetrating member to the penetrating member driver. 11. The device of claim 1 further comprising a damper for slowing said penetrating member prior to said penetrating member reaching a hard stop. 12. The device of claim 1 further comprising a damper coupled to a drive shaft of the penetrating member driver. 13. The device of claim 1 further comprising a damper for slowing the penetrating member on the inbound direction, said damper selected from one of the following: a pneumatic damper, a fluid piston, a rubber stop, a frictional surface, a magnetic fluid based damper, or a rheonetic fluid based damper. 14. The device of claim 1 further comprising an optically reflective member coupled to a drive shaft of the penetrating member driver, said optically reflective member used for determining a positioning. 15. The device of claim 1 further comprising a penetrating member coupler attached to the driver. 16. The device of claim 1 further comprising a disposable containing the plurality of penetrating members. 17. The device of claim 1 further comprising a drum containing the plurality of penetrating members. 18. The device of claim 1 further comprising a drive shaft coupled to the penetrating member driver and a penetrating member coupler. 19. The device of claim 1 further comprising a carrier coupled to said penetrating member driver and movable between a first position and a second position, said penetrating member driver mounted on the carrier and movable with the carrier. 20. The device of claim 1 further comprising a friction damper having a plunger, said damper having a lumen with a funnel shaped portion and an elongate portion, said plunger sized to engage said elongate portion to provide damping. 21. The device of claim 1 further comprising a friction damper on a carrier for slowing said penetrating member, said friction damper shaped to provide variable resistance based on a position of a penetrating member coupler. 22. The device of claim 1 further comprising a reset latch coupled to a carrier, said reset latch configured to hold a penetrating member coupler in place while the driver is compressed. 23. A body fluid sampling device using a penetrating member to extract fluid from an anatomical feature, said device comprising: a rotatable device having a circumferential wall section that runs cylindrically on an outer periphery;a plurality of penetrating members coupled to the rotatable device;a penetrating member driver, said driver selected from one of the following: a motor and gear box, a nanomuscle, a pneumatic device, a liquid magnetic coil actuation device, a stepper motor, a micro-clutch device, and an inductive motor;a penetrating member coupler attached to said driver, said coupler releasably connecting a penetrating member to the driver;a sterility barrier that disposes over the plurality of penetrating members and is configured to maintain the plurality of penetrating members each in a sterile environment prior to launch of the penetrating member to the anatomical feature, the sterility barrier being in a non-contact relationship relative to a tip of the penetrating member;a mechanical sterility barrier removal device configured to breach the sterility barrier and to open the sterile environment to provide that the penetrating member does not pierce any materials when the penetrating member is actuated toward a tissue site;the plurality of penetrating members being arranged radially around an axis of rotation of the rotatable device; anda user interface coupled to a processor, wherein the processor is configured to provide the user interface with an option selected from at least one of, depth of a penetrating member penetration, velocity of the penetrating member, a desired velocity profile, a velocity of the penetrating member into the tissue site, velocity of the penetrating member out of the tissue site, dwell time of the penetrating member in the tissue site, and a target tissue profile with a dwell time sufficient to allow for a spontaneous flow of blood from the tissue site.
