Method and apparatus for penetrating tissue
First Claim
1. A body fluid sampling system for use on a tissue site, the system comprising:
- an electrically powered drive force generator;
a penetrating member operatively coupled to said drive force generator, said drive force generator moving said member along a path out of a housing having a penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;
an analyte sensor associated with the penetrating member;
a cartridge housing said penetrating member and said analyte sensor, said cartridge having a first and a second seal coupled to said penetrating member to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation; and
a user interface coupled to a processor, wherein in response to an input at the user interface by a user the processor providing an input to the drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction.

Abstract
These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes an electrically powered drive force generator. A penetrating member is operatively coupled to the force generator. The force generator moves the member along a path out of a housing having a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A cartridge houses the penetrating member. The cartridge has first and second seals coupled to the penetrating member to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
