A method of accessing an internal portion of a patient including the steps of providing an access assembly including an outer frame, an inner member and a flexible member, inserting the inner member through an opening in tissue into a body of a patient with the flexible member extending proximally through the opening in tissue, moving at least a first portion or second portion of the outer member to a select unlocked spread position to enlarge the opening in tissue and the passageway through the flexible member, and subsequently moving the locking member to move the first and second engagement structures into a locking position to lock the first portion in the select spread position.
