Abstract
A dual lumen cannula includes a first tube defining a return lumen and having a proximal end, a mid-portion and a distal end, wherein the distal end includes a return aperture. A second tube is coaxial with the first tube and has a proximal end and a distal end, wherein the distal end of the second tube is fixedly attached to the mid-portion of the first tube and wherein the distal end of the second tube includes a drainage aperture. A drainage lumen is defined by a space between the first tube and the second tube. A connector is attached to the proximal end of the second tube. The connector includes a reservoir for receiving a fluid from the proximal end of the second tube. The first tube extends through the connector and does not attach directly with the second tube at the connector, and the first tube remains substantially coaxial with the second tube throughout a length of the second tube.
