An apparatus and method for blood dialysis. The device includes a plurality of semipermeable tubules for transporting blood therethrough. Distribution means are positioned adjacent the exterior of the tubules for admitting a dialysis solution which is passed along the outside of the tubules. The tubules are preferably arranged in a configuration such that the packing density of the tubules is between about 20% and about 50%, and preferably between about 25% and about 35%. This packing density insures adequate distribution of the dialysate solution as it is passed along the length of the tubules. The tubules may be wrapped and similarly curved; in a preferred embodiment they are spirally orientated. The configuration of the tubules allows for the movement of the tubule in a predetermined manner such that tubule masking is substantially prevented.
