Abstract

An improved hollow fiber membrane device is obtained using an inner wrap extending no farther than 25 percent of the diameter of the hollow fiber bundle from the central, longitudinal axis of said bundle. The fibers within the inner wrap are not necessarily hollow. Optionally, an elastic outer wrap is also employed about the bundle.
