Abstract
A dilator system includes a series of sequential dilators. A first dilator has an elongated body having a major axis and a minor axis, the minor axis being substantially normal to the major axis. A second dilator has an elongated body having a major axis and a minor axis, the minor axis of the second dilator being substantially normal to the major axis of the second dilator. A bore of the second dilator is configured to matingly receive the first dilator in such a way that the major axis of the second dilator is aligned with the minor axis of the first dilator and the minor axis of the second dilator is aligned with the major axis of the first dilator.
