Abstract

A dilator may include a leading portion that includes a leading end coupled to a leading stem. The dilator may further include a trailing portion that includes a trailing end coupled to a trailing shaft. The dilator may also include a segmented body disposed between the leading end and the trailing end. The segmented body may include a plurality of segments disposed circumferentially around the leading stem. The leading stem may extend through a passageway of the segmented body, an opening of the trailing end and a channel of the trailing shaft. The leading stem and the trailing shaft may be configured to move longitudinally relative to one another to radially outwardly expand the segmented body.
