    摘要: The invention relates to a catheter with a substantially U-bent hollow fiber membrane (10), or to such a hollow fiber membrane (10), that comprises two arms (11, 13) and a bent section (15). According to the invention, the hollow fiber membrane (10) is heat-treated and/or treated with at least one solvent in at least its bent section (15). The inventive catheter has a small overall diameter, is easy to produce and easy to implant or explant. The bent section (15) does not kink so that the lumen remains open. The invention further relates to a method for producing such a catheter or such a hollow fiber membrane.
