ABSTRACT:
A dual lumen vascular catheter with expanding side portal includes a cylindrical tubing with one or more lumens inside. An effusion portal is located on the side of the tubing at an end of one lumen. The portal is oval-shaped, with an open-ended slit connected to an end of the oval opening. The slit is thereby expandable, allowing for vacuum relief during aspiration of blood in the event that the catheter is lodged with the portal pressed against an inner wall of the vein.
