A soft tissue dilator for use in a surgical procedure includes a first dilator member that defines a first axis and a second dilator member that defines a second axis. The second dilator member is supported on the first dilator member such that relative rotational movement of the first and second dilator members causes eccentric movement of the first and second axes defined by the first and second dilator members. Additional dilators members may be sequentially supported on the first and second dilator members.
