Integrated external ventricular drainage and intracranial electroencephalography monitoring device

A method for bodily fluid drainage and bioelectrical monitoring, comprising:

• inserting a distal portion of a flexible tube of a device into a fluid-containing anatomical structure of a subject,
• wherein the device comprises:
• the flexible tube having a shaft extending between a proximal end and the distal portion and a lumen extending longitudinally through the shaft,
• a plurality of perforations in fluid communication with the lumen and disposed at the distal portion, and
• recording electrodes disposed along the shaft;
• draining bodily fluid from the anatomical structure through the plurality of perforations and into the lumen towards the proximal end of the flexible tube;
• and
• obtaining, via the recording electrodes, bioelectrical signals from tissue adjacent to or within the anatomical structure.

A system comprising:

• a device for bodily fluid drainage and bioelectrical monitoring, the device comprising:
• a flexible tube configured for insertion into a fluid-containing anatomical structure of a subject, the flexible tube comprising a shaft extending between a proximal end and a distal portion, a lumen disposed inside of the shaft and extending longitudinally therethrough, and a plurality of perforations at the distal portion in fluid communication with the lumen and configured to enable bodily fluid to flow from the anatomical structure into the lumen and towards the proximal end;
• a plurality of recording electrodes disposed along the shaft and configured to record bioelectrical signals of tissue adjacent to or within the anatomical structure;
• circuitry disposed along the shaft and electrically coupled to the plurality of recording electrodes, wherein a portion of the circuitry extends from the shaft at a location along the shaft that is between the plurality of recording electrodes and the proximal end of the flexible tube;
• and
• an electrical connector comprising electrical pins configured to electrically couple the circuitry to a signal processing device.
