Claim Text:
1. A microfluidic needle comprising: an interface portion containing at least two fluid communication channels; an elongated needle portion projecting away from the interface portion, the needle portion having a tapering tip portion, connected to an exterior sidewall connecting the tip portion to the interface portion, the exterior sidewall extending perpendicularly from the interface portion; and at least two microfluidic channels, being in fluidic and individual connection with one of the at least two communication channels, and extending from the interface portion toward the tip within the needle portion, wherein the at least two microfluidic channels turn perpendicularly within the needle portion so that each of the at least two microfluidic channels exits only at the sidewall extending perpendicularly from the interface portion on different sides of the top half of the needle portion under the tip so as to prevent clogging.
