A method for influencing cerebral perfusion in a patient by modifying a volume of a volume adaptor introduced into a cerebral ventricle of the patient, the method comprising identifying a timing of a cerebral blood inflow and/or outflow in a cardiac activity of the patient, modifying a volume of the volume adaptor in synchronization to the identified timing of the cerebral blood flow, to an amount sufficient to modify an intracranial pressure in the cerebral ventricle, such that a flow of the cerebral blood flow is enhanced. In some exemplary embodiments of the invention, the inflation duration of the volume adapter is short relative to the cardiac cycle.

Intracranial volume adaptor for cerebral blood flow

A method of estimating cerebral blood flow includes obtaining a measure of time-varying blood volume in the head, using an impedance plethysmography (and), obtaining a measure of time-varying blood volume in the scalp, and using the time-varying blood volume in the head and scalp to estimate cerebral blood flow.
