ABSTRACT:
A method and apparatus for fluid transfer across a membrane wherein transfer fluid is passed through the interior of a wrapped, permeable, flattened, tubular membrane and fluid to be processed is passed through passageways formed between the wrappings of the tubular membrane. The transfer fluid flow rate and pressure are maintained at a substantially constant level. In preferred embodiments the method and apparatus are utilized to oxygenate blood and/or provide for kidney dialysis.
