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 injecting a medicament to a body part, comprising: a housing;a penetrating member positioned in the housing, the penetrating member including a widened portion and a tip;a medicament injection source configured to be coupled to the penetrating membera deformable member sealing the housing;wherein, during a medicament injection 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 injection movement and enlarging the opening; anda cover sheet with a proximal surface with a spatial separation from a distal surface of a lancet cartridge body at a penetrating member channel site, the spatial separation of the proximal surface of the cover sheet from a distal surface of the lancet cartridge body being between the two surfaces that is formed into the distal surface of the lancet cartridge body,the deformable member configured to reseal after the penetrating member tip has penetrated it while injection medicament from the medicament injection source; wherein, during the injection movement, the portion of the deformable member pierced by the tip becomes flared. 2. The penetrating member system of claim 1, wherein after the injection 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 injection movement, the deformable member remains substantially intact. 4. The penetrating member system of claim 1, wherein the widened portion is a substantially conical shape. 5. The penetrating member system of claim 4, wherein a radius of the widened portion increases in a direction along the penetrating member away from the tip. 6. The penetrating member system of claim 1, wherein the widened portion is positioned adjacent to the tip. 7. 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. 8. The penetrating member system of claim 1, 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. 9. The penetrating member system of claim 8, 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 injection movement to move the tip toward the deformable member. 10. The penetrating member system of claim 1, wherein during the injection movement, the widened portion enlarges the opening to a size that is substantially larger than the size of the tip.
