IMPLANTABLE PRESSURE INDICATOR WITH EXTERNAL INTERROGATION

摘要

Observing intracranial physiology includes inserting a bladder at least partially filled with a fluid into a subdural region of interest within a subject, wherein the bladder is coupled in flow communication with a means of indicating a pressure exerted on the bladder within the region of interest. Embodiments also include non-invasively interrogating the means of indicating to determine the pressure exerted on the bladder.
