Abstract
Leucocyte depletion filter assemblies decrease the leucocyte content of a biological fluid in an extracorporeal circuit. These filter assemblies are suitable for use in an extracorporeal circuit. Methods for removing leucocytes and other deleterious matter are also disclosed. The removal medium used in these assemblies and methods may be pleated structures which have been subjected to gas plasma treatment, improving the amount of leucocytes removed and increasing the amount of platelets which pass through the medium.
