An implantable device for recording intracranial pressures, wherein a pressure sensor is used that interfaces with a data transmitter, and wherein the pressure sensor is a microchip and the microchip is located in a rigid housing, wherein a window is provided in the housing for transferring the pressure and the window is sealed with a thin membrane, wherein the membrane is preferably made of a biocompatible metal, and wherein the membrane acts on a volume of fluid, preferably on a volume of gas as the pressure mediator that transfers the pressure changes on the membrane to the pressure sensor, wherein the membrane possesses at least one corrugation wherein the corrugation has at least one outward bulge with a radius that is at least equal to a multiple of the thickness of the membrane, wherein the membrane thickness is in the range of 0.005 millimeters to 0.04 millimeters.
A method for manufacturing an implantable device for recording intracranial pressures, wherein a pressure sensor is used that interfaces with a data transmitter, and wherein the pressure sensor is a microchip and the microchip is located in a rigid housing, wherein a window is provided in the housing for transferring the pressure and the window is sealed with a thin membrane, wherein the membrane is preferably made of a biocompatible metal, and wherein the membrane acts on a volume of fluid, preferably on a volume of gas as the pressure mediator that transfers the pressure changes on the membrane to the pressure sensor, wherein the membrane possesses at least one corrugation wherein the corrugation has at least one outward bulge with a radius that is one of (a), (b), (c), and (d), wherein (a), (b), (c), and (d) are:
