摘要：
A surgical access system comprising a tissue dilation assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures and one or more pressure sensors for determining and monitoring pressure on neural structures near the tissue dilation assembly or the tissue retraction assembly.
