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 penetrating member system for withdrawing body fluid from a body part, comprising: a housing;a penetrating member reciprocally disposed in the housing, the penetrating member including a widened portion and a tip; anda deformable member sealing the housing,wherein, during a puncture movement of
1. A penetrating member system for withdrawing body fluid from a body part, comprising: a housing;a penetrating member reciprocally disposed in the housing, the penetrating member including a widened portion and a tip; anda deformable member sealing the housing,wherein, during a puncture movement of the penetrating member, the tip pierces the deformable member to produce an opening in the deformable member, the widened portion contacting the deformable member during the puncture movement and enlarging the opening; andthe deformable member configured to reseal after a penetrating member tip has penetrated it without physically affecting the penetrating member's cutting tip and edges; wherein the housing includes a first end and a second end, the first end including the deformable member and the second end having a second film. 2. The penetrating member system of claim 1, wherein after the puncture movement, the tip retracts into the housing and the opening substantially maintains its shape after the retraction. 3. The penetrating member system of claim 1, wherein during the puncture movement, the deformable member remains substantially intact. 4. The penetrating member system of claim 1, wherein, during the puncture movement, the portion of the deformable member pierced by the tip becomes flared. 5. The penetrating member system of claim 1, wherein the widened portion is a substantially conical shape. 6. The penetrating member system of claim 5, wherein a radius of the widened portion increases in a direction along the penetrating member away from the tip. 7. The penetrating member system of claim 1, wherein the widened portion is positioned adjacent to the tip. 8. The penetrating member system of claim 1, wherein the penetrating member defines a needle having the tip and the widened portion, the needle being at least partially surrounded by a penetrating member body. 9. The penetrating member system of claim 1, wherein the second film is configured to be pierced by an actuator and the penetrating member is adapted to be driven by the actuator during the puncture movement to move the tip toward the deformable member. 10. The penetrating member system of claim 1, wherein during the puncture movement, the widened portion enlarges the opening to a size that is substantially larger than the size of the tip. 11. A penetrating member system, comprising: a housing;a penetrating member reciprocally disposed in the housing, the penetrating member including a widened portion and a tip, the penetrating member configured to be movable between a retracted position and an extended position during a puncture movement; andwherein in the retracted position, a deformable member seals the housing and the tip is surrounded by the housing, in the extended position of the penetrating member, the tip extends through an opening in the deformable member that is created when the tip pierces the deformable member during the puncture movement, the widened portion contacting the deformable member and defining a size of the opening in the extended position, the deformable member configured to reseal after a penetrating member tip has penetrated it without physically affecting the penetrating member's cutting tip and edges; wherein during the puncture movement, the portion of the deformable member pierced by the tip becomes flared. 12. The penetrating member system of claim 11, wherein the widened portion is a substantially conical shape. 13. The penetrating member system of claim 12, wherein a radius of the widened portion increases in a direction along the penetrating member away from the tip. 14. The penetrating member system of claim 11, wherein after the puncture movement, the penetrating member retracts into the housing from the extended position to the retracted position and the opening in the deformable member substantially maintains its shape and size. 15. The penetrating member system of claim 14, wherein as the penetrating member retracts to the retracted position, the penetrating member does not contact the deformable member. 16. The penetrating member system of claim 11 wherein during the puncture movement, the deformable member remains substantially intact. 17. The penetrating member system of claim 11, wherein in the extended position, a size of the opening is defined by the widened portion in contact with the deformable member. 18. The penetrating member system of claim 11, wherein the widened portion enlarges the opening to a size that is substantially larger than a size of the tip.
