Abstract

The invention relates to a filter device, preferably for hemodialysis, that consists of a cylindrical filter housing and a bundle of curled hollow fibers. The bundle is arranged in the filter housing. According to the invention, the curled hollow fibers are provided with an essentially sinusoidal texture and a wavelength that is defined by means of certain limits. The invention also relates to a curled hollow fiber and a method for filling a hollow fiber dialyser.
