We claim: 1. A device, comprising: (1) a housing having an interior and an exterior; (2) a flexible member within the interior of the housing and mechanically coupled to the housing, the flexible member forming first and second chambers within the interior of the housing; (3) a fluid reservoir within the first chamber of the housing; and, (4) a microprobe extending from the fluid reservoir, through the flexible member and into the second chamber of the housing, the microprobe being configured to translate in a first direction and rotate substantially freely in plane perpendicular to the first direction. 2. The device of claim 1, wherein a first end of the microprobe is in the fluid reservoir and a second end of the microprobe is capable of extending to the exterior of the housing. 3. The device of claim 1, wherein the microprobe is mechanically coupled to the flexible member. 4. The device of claim 1, wherein the microprobe comprises a needle. 5. The device of claim 1, wherein the microprobe comprises a microneedle. 6. The device of claim 1, wherein the flexible member comprises a septum. 7. The device of claim 1, further comprising a pump in fluid communication with the fluid reservoir. 8. The device of claim 7, wherein the pump is configured to draw a fluid from the microprobe into the fluid reservoir. 9. The device of claim 7, wherein the pump is configured to deliver a fluid from the fluid reservoir to the microprobe. 10. The device of claim 9, wherein the pump comprises a gas generating source. 11. The device of claim 9, wherein the pump comprises an electrochemical cell. 12. The device of claim 7, wherein the pump comprises a gas generating source. 13. The device of claim 7, wherein the pump comprises an electrochemical cell. 14. The device of claim 1, wherein the device comprises a second device for delivering a fluid from the fluid reservoir to the exterior of the device via the microprobe. 15. The device of claim 1, wherein the device comprises a second device for delivering a fluid to the fluid reservoir from the exterior of the device via the microprobe.
