The development of the Fresenius Polysulfone® membrane was based on the function of the natural kidney, and the membrane provides a wide range of performances for all haemodialysis therapies.

Numerous scientific publications and millions of treatments reflect the good experiences and satisfaction of clinical staff and patients with this synthetic membrane. Commonly regarded as the "gold standard" for dialysis membranes, Fresenius Polysulfone® has stood for performance and safety in haemodialysis for three decades.

Continuing to set standards for innovative dialysis products, Fresenius Medical Care developed an advanced Fresenius Polysulfone® -based dialysis membrane - the Helixone®.

The Helixone® membrane is manufactured using a new process involving Nano Controlled Spinning (NCS) technology. By means of this technology it is possible to create the inner membrane layer with a defined pore structure and pore distribution profile according to the desired application.

Helixone® is the advanced high-flux polysulfone membrane of the FX-class of dialysers. Helixone® has been designed specifically to meet the present day demands of high-flux dialysis and convective therapies such as Haemodiafiltration (HDF).

The technological advances of the FX-class are all directed towards improving the therapy and the wellbeing of the patient. Extended worldwide clinical experience has already established the new FX-class range as the dialysers of choice for routine high-flux dialysis and ONLINE HDF.
