Abstract
A method of performing minimally invasive cardiac surgery includes the step of creating an access aperture into a patient's chest cavity, the access aperture being considerably smaller than a traditional cardiac surgery incision. A cannula is provided that has an oval portion with a longer major axis and a shorter minor axis and the cannula is inserted into the chest cavity through the access aperture.
