When FX-class® dialyzers were introduced into the market, an innovative spinning technology had been developed to produce its Helixone® membrane. The so called Nano Controlled Spinning (NCSTM) technology allowed the production of highly-defined pore structures. Opposed to the previously produced conventional pores which were rugged and uneven in shape, the pores at the inner layer of the Helixone® membrane are smooth and cylindrical. This reduces the resistance of the molecules when travelling through the pores and therewith allow for enhanced removal.
Optimized pore spectrum through nanotechnology
All Helixone® membranes offer optimized sieving properties as the pore size distribution has been tightened compared to previously produced membranes as used e.g. in the F-series. The average pore size is larger compared to F-series dialyzers and the variance in pore sizes is smaller. This results in a better selective permeability for middle molecules, i.e. a more favorable β2-m / albumin sieving proportion.
