1. An apparatus for a minimally-invasive, including non-invasive, modulation of intracranial pressure, the apparatus comprising:
a housing being sized for superjacent contact on a skull having a fontanel, the housing including an opening sized for the fontanel;
the housing securing a compartment, a pressure regulator, and a controller therein;
the controller being interconnected communicatively with each of the compartment and the pressure regulator;
the compartment including a pressure applicator under control of the pressure regulator, the pressure applicator being configured to selectively apply an external pressure to the fontanel;
the controller, if a clinical goal is at least one of to treat hydrocephalus and prevent hydrocephalus, selectively withdrawing the pressure applicator from the fontanel during systole and selectively extending the pressure applicator to the fontanel during diastole; and
the controller, if the clinical goal is to increase cerebral blood flow, selectively extending the pressure applicator to the fontanel during systole and selectively withdrawing the pressure applicator from the fontanel during diastole.
