Abstract
A cannula has a distal portion which is angled relative to a proximal portion. The distal portion is straightened during introduction with a stiffening element. After introduction, the stiffening element is removed so that the distal portion angulates relative to the proximal portion so that the cannula can be moved out of the surgical field. The cannula preferably includes a stabilizing ring having suture holders. The stabilizing ring is also preferably angled relative to the cannula.
