A tissue penetration device and method of using same that may include a lancet module or sampling module. The sampling module may optionally be in a cartridge configuration and include sampling and analyzing functions, which may be integrated.
What is claimed is: 1. A sampling module, comprising a module body portion comprising a lancet channel with a plurality of lancet bearing guides disposed within the lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel and
What is claimed is: 1. A sampling module, comprising a module body portion comprising a lancet channel with a plurality of lancet bearing guides disposed within the lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel and lancet bearing guides with the lancet bearing guides configured to confine a lancet to substantially linear axial movement; and a sample reservoir in fluid communication with a sample input port of the module body portion. 2. The sampling module of claim 1 wherein the module body portion comprises three lancet bearing guides separated spatially along the lancet channel with a lancet bearing guide disposed at either end of the lancet channel. 3. The sampling module of claim 1 wherein a longitudinal axis of the lancet channel is substantially parallel to a longitudinal axis of the module body portion. 4. The sampling module of claim 1 wherein the lancet channel further comprises at least one flow stop chamber disposed within a distal end portion of the lancet channel that has a transverse dimension that is significantly larger than a transverse dimension of a distally adjacent portion of the lancet channel and a rapid transition in transverse dimension that will interrupt capillary action from a distal end of the lancet channel. 5. The sampling module of claim 1 wherein the module body portion is configured to be mechanically registered and secured adjacent a lancet driver. 6. A sampling module, comprising: a module body portion configured to be mechanically registered and secured adjacent a lancet driver; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the module body portion; and a sample reservoir in fluid communication with a sample input port of the module body portion that has a fill detector for determining when the sample reservoir is full of a sample. 7. The sampling module of claim 6 wherein the fill detector is electrical. 8. The sampling module of claim 6 wherein the fill detector is optical. 9. The sampling module of claim 6 wherein the fill detector is visual. 10. A sampling module, comprising: a module body portion comprising a lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancer channel of the module body portion; a first sample reservoir having an input end and a terminal end, the input end of the sample reservoir being in fluid communication with a sample input port of the module body portion; and a second sample reservoir having an input end in fluid communication with the terminal end of the first sample reservoir and having a cross sectional area that is substantially smaller than a cross sectional area of the first sample reservoir such that a sample flowing from the simple input port into the first sample reservoir will fill the first sample reservoir and then rapidly fill the second sample reservoir by capillary action. 11. The sampling module of claim 10 wherein a terminal end of the second sample reservoir further comprises a fill detector. 12. The sampling module of claim 11 wherein the fill detector is electrical. 13. The sampling module of claim 11 wherein the fill detector is optical. 14. The sampling module of claim 11 wherein the fill detector is visual. 15. A sampling module, comprising: a module body portion comprising a lancet channel having at least one flow stop chamber disposed within a distal end portion of the lancet channel tat has a transverse dimension that is significantly larger than a transverse dimension of a distally adjacent portion of the lancet channel and a rapid transition in transverse dimension that will interrupt capillary action from a distal end of the lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel; and a sample reservoir in fluid communication with a sample input port of the module body portion, wherein the module body portion comprises three lancet bearing guides separated spatially along the lancet channel with a lancet bearing guide disposed at either end of the lancet channel. 16. A sampling module, comprising: a module body portion comprising a lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel of the module body portion; a sample reservoir having an input end and a terminal end, the sample reservoir being in fluid communication with a sample input port of the module body portion; and a vent disposed between and in fluid communication with the terminal end of the sample reservoir and the lancet channel, wherein the terminal end further comprises a fill detector. 17. A sampling module, comprising: a module body portion comprising a lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel of the module body portion; a sample reservoir having an input end and a terminal end, the sample reservoir being in fluid communication with a sample input port of the module body portion; and a vent disposed between and in fluid communication with the terminal end of the sample reservoir and the lancet channel, wherein the terminal end further comprises a fill detector and wherein the fill detector is electrical. 18. A sampling module, comprising: a module body portion comprising a lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel of the module body portion; a sample reservoir having an input end and a terminal end, the sample reservoir being in fluid communication with a sample input port of the module body portion; and a vent disposed between and in fluid communication wit the terminal end of the sample reservoir and the lancet channel, wherein the terminal end further comprises a fill detector and wherein the fill detector is optical. 19. A sampling module, comprising: a module body portion comprising a lancet channel; a lancet comprising a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel of the module body portion; a sample reservoir having an input end and a terminal end, the sample reservoir being in fluid communication with a sample input port of the module body portion; and a vent disposed between and in fluid communication with the terminal end of the sample reservoir and the lancet channel, wherein the terminal end further comprises a fill detector and wherein the fill detector is visual.
