摘要：
A dilation system for accessing a surgical target site to perform surgical procedures. In one version, the dilation system includes a plurality of open sided dilators having non-circular cross sections and configured to slidably and non-rotationally engage with one another in a sequential manner. In another version, the dilation system includes an expandable dilator movable from a closed condition to an expanded condition.
