ABSTRACT:
A dual lumen subclavian cannula is disclosed for use in hemodialysis where the lumens are formed by a septum dividing an essentially circular tube longitudinally. The blood return lumen is closed at its distal end by a blunt point and has openings in its side wall proximal to the point. The blood inlet lumen has an open distal end plus openings in the side wall which are proximal to the analogous openings in the blood return lumen. A manifold at the proximal end of the tube separately distributes blood into the return lumen and collects blood from the inlet lumen.
