An anatomical space access device having an elongate body; an insertion tip at a distal end of the elongate body; an anatomical space sensor disposed at the distal end of the elongate body, the sensor being adapted to sense a parameter identifying an anatomical space other than a vasculature space and to generate a signal; and an indicator operatively connected to the sensor to receive the signal and to indicate access of the sensor to the anatomical space. The invention also provides a method for providing access to an anatomical space outside of a vasculature space, including the following steps: inserting a distal end of an instrument through a tissue volume into the anatomical space outside of a vasculature space, the instrument comprising an anatomical space sensor; and generating a location indication of the anatomical space sensor.
