Abstract
The present invention provides minimally invasive subdural evacuating systems and methods of use thereof. The subdural evacuating systems include a cutting component and a rod component, wherein the rod component provides an external physical indicator that the surface of the dura mater has been reached, permitting the cutting component to accurately pierce the dura mater with minimal to no risk of damaging any adjacent anatomy.

A method of piercing a dura mater, comprising the steps of:
- advancing an apparatus into a subject's skull through a port towards a dura mater surface until a surface of a component of the apparatus touches the dura mater surface such that the component ceases advancement into the subject's skull;
- ceasing advancement of the apparatus at a position where the component ceases advancement into the subject's skull;
- and
- indexing the position of the apparatus relative to the dura mater surface such that accurate cutting of the dura mater surface is permitted with minimal to no risk of damaging any adjacent anatomy.
