The multi-lumen cannula according to the invention is preferably formed from two separate sub-cannulas, a portion of which are adhered to one another. Preferably, the adhered portions of the sub-cannulas are deformed such that the assembled multi-lumen cannula is substantially circular in cross section throughout the adhered portions of the sub-cannulas. In addition, the septum separating the multiple lumens of the cannula is preferably reinforced so that the multi-lumen cannula can accommodate dramatically different fluid pressure within the cannula without deformation of the septum. This cannula is ideally suited for use in a variety of left-heart and right-heart assist cardiac surgical procedures, especially minimally invasive procedures. |
