1. A tissue penetration device for generating a piercing wound in a skin surface to obtain body fluid, comprising:
- a housing with an analyzer device that has an exterior surface;
a cartridge with a cartridge body and at least one sampling module portion, the sampling module portion having a housing with an orientation sensitive contact interface for mating with the exterior surface of the analyzer device, the contact interface configured to align the sampling module cartridge with the exterior surface analyzer device;
a penetrating member and the sampling module portion positioned in the cartridge;
an electronic driver configured to be coupled to the penetrating member;
feedback control coupled to the electronic driver;
a processor coupled to the electronic driver and the feedback control that in operation is configured to regulate energy delivery to the electronic driver from a power supply and controls penetrating member advancement and retraction, the processor storing user profile information that is used for future lancing events, the processor in operation being configured to customize user profiles by scaling or modifying the profile based on additional user input information and in response to a customization modulates power from the a power supply; and
wherein the at least one sampling portion including a sample reservoir and a lancet channel with a vent at an outward radial end that allows the sample reservoir to fill with a fluid sample, the sample reservoir being in fluid communication with a respective lancet channel which extends substantially parallel to a longitudinal axis of the cartridge body.

Abstract
A tissue penetration device includes a magnetic source that produces a controllable magnetic field in a magnetically active region adjacent the magnetic source. A magnetic member is disposed at least partially in the magnetically active region. A permanent magnet is disposed at a proximal end of the magnetically active region for zeroing the position of the magnetic member while the tissue penetration device is inactive.
