A multi-lumen miniature ribbon tube is generally flat in overall shape, and includes a number of generally parallel, longitudinal lumens arranged sequentially. Each lumen includes a tubular polymer sidewall defining a separate longitudinal fluid passageway. (Here, "lumen" refers to a sidewall and passageway in combination.) The lumens are integrally formed, but may be frangible from one another. The sidewall may be made of FEP or ETFE. The ribbon tube may be as wide as 3.5 inches, and each lumen has a passageway diameter of 0.005 to 0.050 inches. Using minimum dimensions, a 3.5-inch wide ribbon tube has more than 200 lumens, each of which provides a separate fluid passageway. This enables a multiplicity of fluids to be delivered to one location. Additionally, because the lumens are frangible, one or more fluids may be delivered to multiple localized locations by separating the lumens proximate the tubing's end.
