Method and apparatus for body fluid sampling and analyte sensing
First Claim
1. A body fluid sampling system for use on a tissue site, the system comprising:
- a cartridge;
a penetrating member driver;
a plurality of penetrating members arranged in a radial configuration on the cartridge wherein sharpened distal tips of the penetrating members point radially outward;
wherein an active one of said penetrating members may be operatively coupled to said penetrating member driver, said penetrating member driver moving said active one 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; and
a plurality of analyte detecting members, wherein at least one of said analyte detecting members is positioned to receive fluid from a wound created by said active one of said penetrating members, wherein at least one of said detecting members is mounted about a penetrating member exit.
