An active cannula which does more than merely maintain a passage is usable to create and / or enlarge a passage, to position a scope or instrument, to move or locate tissue, etc. The cannula can vary in size or shape as needed, intraoperatively. Because a cannula of the present invention is expandable, the surgeon can make a relatively small incision, stretch the tissue with the expandable cannula, contract the cannula and remove it, allowing the skin to come back to its unstretched condition. Thus, a smaller incision can be made to fit the same size instrument. The cannulas can assume such a non-circular shape, to fit into a natural skin opening and cause less trauma. The devices can be used to seal off a space, expand an existing space or a potential space for working or visualization, move tissue (for example, to stretch an incision), or protect tissue.

To more accurately control insertion of penetrating instruments (e.g., trocars, needles, or the like) into a body cavity, organ, or potential space, an accelerometer is coupled to the penetrating instrument. The accelerometer may by employed to measure or detect the sudden lack of resistance which occurs when the penetrating instrument penetrates to a predetermined depth (e.g., through the abdominal cavity, vein, or outer bone) in a more accurate and reliable way instead of practitioners' subjective feeling. An acceleration sensor (i.e., accelerometer) coupled to the penetrating instrument (e.g., trocar or the like) may transform the physical variable ‘resistance change’ into an electronic signal that is then processed in an electronic circuit, and finally triggers an audible / visible alarm and / or feeds an actuating mechanism to control movement of the penetrating instrument.
