Method and apparatus for penetrating tissue
First Claim
1. A body fluid sampling system for use on a tissue site, the system comprising:
- a drive force generator;
a plurality of penetrating members operatively coupled to said force generator, said force generator moving each of said members 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;
a plurality of analyte sensors, each of an analyte sensor of the plurality of analyte sensors being associated with a penetrating member;
a flexible support member carrying said penetrating members parallel to each other on its top to define an array, said support member being movable and configured to move each of said penetrating members to a launch position associated with said force generator; and
a position sensor configured to provide an indication of a position of the penetrating member during 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 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 a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
