ABSTRACT:
Methods for aspirating a space within the body of a patient, such as the subdural space, including providing an evacuating port device having an evacuating lumen in fluid communication with the space in the body. A port aspiration device is mounted on the evacuating port device, creating fluid communication between an aspiration channel of the port aspiration device and the evacuating lumen. An instrument is positioned in the aspiration channel so that the instrument is capable of entering the evacuating lumen of the evacuating port device. The instrument can dispense medication and/or remove materials from the lumen or the space in the body. The evacuating port device can be mounted to a patient's skull.
