Method and apparatus for penetrating tissue
First Claim
1. A body fluid sampling system for use on a tissue site, the system comprising:
- a single drive force generator;
a plurality of penetrating members operatively coupled to said force generator, said force generator moving each of said penetrating members along a path out of a housing through a penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing each penetrating member out of said tissue site back into said housing;
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 coupling said penetrating members to define a linear 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 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.
