ABSTRACT:
An electrode device is disclosed comprising a deformable envelope, further comprising recording electrodes and a pressure recording port. The device allows for monitoring of brain retraction pressure and local cortical electrical activity including DC potential, as well as redistribution of the force applied during retraction and cushioning of the rigid edges of the brain retractor, thereby diminishing the chance of focal brain injury during surgery. Retraction pressure recorded is equal over the full area of contact. A means is disclosed for optional evacuation of air from the system to improve accuracy and fidelity of the pressure measurements. Local brain hypothermia may be induced via the bladder and attached catheter, thereby providing additional neuroprotection during brain retraction. The device also allows for measurement of intracranial pressure, DC potential, EEG and, optionally, other physiologic parameters in epileptic and severe head trauma patients for management of edema and injury.
