ABSTRACT:
A double lumen continuous flow hemodialysis needle and cannula having contiguous lumens of different lengths, the shorter lumen acting as blood intake lumen and the longer as a blood return lumen, each lumen having a beveled edge sloping outwardly and away from the needle which can be inserted percutaneously and which minimizes the possibility of mixing cleansed blood with blood entering the intake lumen.
