US Patent:

44039832, Sep 13, 1983

Filed:

Nov 6, 1981

Appl. No.:

6/318715

Inventors:

William Edelman - Long Beach CA
Michael Baranowski - Corona Del Mar CA

Assignee:

Shiley Incorporated - Irvine CA

International Classification:

A61M 2500

US Classification:

604 43

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.
