Claim:
A subdural evacuation port aspiration system for permitting evacuation and aspiration of a subdural space of a patient, the subdural evacuation port aspiration system comprising: an evacuation port device including a rigid tubular portion forming a threaded exterior surface configured for partial insertion into an opening in, and engagement with, a skull of the patient, the tubular portion defining an evacuation lumen; a port aspiration device for facilitating aspiration of the evacuation port device when the port aspiration device is mounted on the evacuation port device, the port aspiration device defining an aspiration channel, the port aspiration device comprising: a mounting portion configured to mount on the evacuation port device, the mounting portion defining a first portion of the aspiration channel; an aspiration portion for receiving an aspiration device, the aspiration portion defining a second portion of the aspiration channel; and a negative pressure connection portion for connecting to a negative pressure source, the negative pressure connection portion defining a third portion of the aspiration channel; wherein when the port aspiration device is mounted onto the evacuation port device the aspiration channel is in fluid communication with the evacuation lumen and the evacuation lumen, the first portion of the aspiration channel, and the second portion of the aspiration channel combine to rigidly define a common, linear central axis; and further wherein the second and third portions diverge from one another in extension from the first portion; a negative pressure source; and flexible tubing connectable with the negative pressure source and the negative pressure connection portion to establish fluid communication between the negative pressure source and the third portion of the aspiration channel.
