Abstract
The invention relates to a bundle of hollow fibers intended to constitute the membrane of a device for treating blood or plasma by extracorporeal circulation, in which:the hydraulic permeability of the hollow fibers in the bundle is heterogeneous; andthe ratio of the highest hydraulic permeability measured on some hollow fibers of the bundle to the lowest hydraulic permeability measured on other hollow fibers in the same bundle is at least about 5.The invention also relates to a method for producing such a bundle, and a device comprising such a bundle.
