Abstract
A dilating cannula includes a radially expandable flange and an expandable shaft. The radially expandable flange is disposed at a proximal end portion of the dilating cannula and includes two or more sectors that are each independently movable. The expandable shaft extends from the proximal end portion to a distal end portion of the dilating cannula and defines an inner passageway of the dilating cannula and includes two or more arms. A first branch of the two or more arms extends from one end of the base section and a second branch of the two or more arms extends from another end of the base section. The first branch is connected to a first sector of the two or more sectors of the radially expandable flange and the second branch is connected to a second, different sector of the two or more sectors of the radially expandable flange.
