Two lumen hemodialysis catheter

A catheter comprising a tube having a circular external cross section, a fitting rotatably mounted on said tube so as to surround said cross section, said tube being rotatable about its axis relative to said fitting, said fitting having a projection adapted to be attached to the skin of a patient whose blood vessel is percutaneously catheterized by said catheter, and stop means fixed to said tube on opposite sides of said fitting and preventing said tube from moving longitudinally relative to said fitting, whereby said catheter can be rotated relative to said fitting in order to readjust the rotational position of said tube inside the blood vessel without longitudinal movement of the tube and without separating the attachment of the projection to the skin, wherein said catheter is a two lumen hemodialysis catheter, wherein said lumens are side-by-side, said catheter having a distal end, one of said lumens extending all the way to the distal end of said catheter, said catheter being cut off at said distal end perpendicularly to the length of said tube to define the mouth of said one lumen, said tube being tapered from said cut off distal end to a point proximal of said distal end, said point being approximately three centimeters from said distal end, said taper of said tube defining at least a portion of the mouth of said second lumen.
