Method and apparatus for penetrating tissue
First Claim
1. A fluid delivery system for use on a tissue site, the system comprising:
- an electrically powered drive force generator;
an injection penetrating member operatively coupled to said electrically powered drive force generator, said electrically powered drive force generator moving said injection penetrating member along a path out of a housing having the injection penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;
a disposable housing said injection penetrating member, said disposable couple to a first and a second seal 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 provides an input to the electrically powered drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction and an amount of fluid injected.

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.
