A cannula comprises a proximal end, a distal end, and a lumen extending between the proximal and distal ends, wherein at least a portion of the cannula body is non-circular in cross section, preferably oval. A cannula wherein a portion of the cannula body is oval in cross section is ideally suited in surgical procedures wherein the cannula extends through a percutaneous aperture. The oval portion of the cannula body utilizes the space of the percutaneous aperture efficiently, thereby minimizing the necessary size of the access aperture.
