1. A tissue penetration device, comprising:
- an electronic penetrating member driver;
a cartridge;
a plurality of penetrating members integrated with the cartridge, each of a penetrating member coupled to the electronic penetrating member driver when advanced along a path into a tissue target; and
a user interface coupled to a processor with a memory, wherein in response to an input at the user interface by a user the processor modulates power from a power supply to the electronic penetrating member driver through an amplifier to provide an electrical input to the electronic penetrating member driver to adjust an application of force to a penetrating member and achieve a desired speed of a penetrating member, adjust an application of force applied to the penetrating member when the penetrating member contacts target tissue so that the penetrating member penetrates target tissue within a desired range of speed, determine when contact with a skin surface is made by a tip of the penetrating member, monitor speed of the penetrating member as the penetrating member moves in first direction toward the target tissue, determine whether the distal end of the penetrating member has reached a brake depth, and control a withdraw force from the target tissue, with spontaneous body fluid flow from a patient that is collected in a sample chamber.

Abstract
A tissue penetration device includes a penetrating member driver, a cartridge, and a plurality of penetrating members integrated with the cartridge. Each of a penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A user interface is configured to relay at least one of, skin penetrating performance or a skin penetrating setting.
