An expandable access device for providing access to a surgical site and incorporating a mobility member. The expandable access device may have an access portion, an expandable portion, a mobility member connecting the access portion and the expandable portion, and a passageway extending therethrough. The mobility member may connect the access portion and the expandable portion so that the access portion may be translated and/or rotated relative to the expandable portion using a surgical or diagnostic instrument/device and/or a finger. The access portion may have a fixed cross-section or may be expandable. Moreover, the expandable portion of the expandable access device may have an unexpanded and expanded position. One or more tools may be inserted through the passageway and may be used to move the expandable portion between the expanded and unexpanded position. The expandable access device may be inserted into the body down towards a surgical site, with the expandable portion in the unexpanded position. Once in position, the expandable portion may be moved to the expanded position. A surgeon may insert instruments and/or devices through the passageway to the surgical site to perform a surgical procedure. Once the procedure has been completed, the expandable portion may be moved to the unexpanded position and removed from the body.
