A tissue penetration device and method of using same. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. An embodiment provides control of a lancet used for sampling blood. Electric field coils or solenoids may drive the lancet using electromagnetic force. Advancement and retraction of a lancet may be controlled by a feedback loop monitoring the position and velocity of the lancet embodiments of the lancet driver can be configured to follow a predetermined tissue lancing profile. Embodiments of the invention include a lancet and method for using a lancet to maintain the patency of the wound tract once the lancet has cut into the skin.
1. A body fluid collection system, comprising: a housing with a body fluid sample chamber and a sample transport channel;a plurality of penetrating members each with a sharpened tip;a cartridge positionable in the housing;a penetrating member body positionable in the cartridge;an advancement device
1. A body fluid collection system, comprising: a housing with a body fluid sample chamber and a sample transport channel;a plurality of penetrating members each with a sharpened tip;a cartridge positionable in the housing;a penetrating member body positionable in the cartridge;an advancement device coupled to the penetrating member body and configured to move the penetrating member body in the cartridge to position an un-used penetrating member in a launch position;a penetrating member driver configured to be coupled to the penetrating member, drive the penetrating member along a movement path to penetrate a skin surface in a first direction during a penetration phase, and withdraw the penetrating member in an opposing second direction during a retraction phase; andan audible signal generator configured to provide an audible signal of results. 2. The system of claim 1, wherein the penetrating member driver is controllable. 3. The system of claim 1, further comprising: a processor that determines when a penetrating member has contacted a skin surface. 4. The system of claim 1, wherein a position of the skin is detected prior to launch of the penetrating member. 5. The system of claim 1, wherein the penetrating member driver includes an actuator spring. 6. The system of claim 5, further comprising: a penetrating member driver sleeve and a penetrating member plunger sleeve. 7. The system of claim 6, wherein the penetrating member driver sleeve, penetrating member plunger sleeve, and actuator spring move outward together until a plunger head contacts a bottom of a counterbore at an end of a preload screw.
