Abstract
A cannula, system, and method for de-airing a patient's heart following surgery are described. The cannula includes a tubular wall having a distal end portion and a proximal end portion. The wall also has a length extending from the distal end portion to the proximal end portion. The wall at least partially defines a first lumen extending lengthwise of the wall into the distal end portion and terminating in a closed first end. The wall also at least partially defines a second lumen extending lengthwise of the wall and terminating in a closed second end. The wall is configured and dimensioned such that the cannula can be inserted into the patient's heart. A first aperture extends through the wall from the first lumen to an exterior surface of the wall. A second aperture extends through the wall from the second lumen to the exterior surface of the wall.
