Abstract: An implantable medical device system is provided with multiple medical devices implanted in a patient's body and a wireless mesh communication network providing multiple communication pathways between the multiple medical devices. A communication pathway between a first and a second implanted device of the multiple medical devices can comprise one or more of the other implanted multiple medical devices.

Abstract: A power source of an implantable medical device (IMD) is connected to one or more components that perform various functions of the IMD via an acoustic switching circuit. The acoustic switching circuit may include one or more switches that when open disconnect the one or more components from the power source and when closed connect the one or more components to the power source to activate the one or more components. Various techniques for connecting the components to the power source are described. These techniques aim to reduce the likelihood of inadvertently connecting the power source to the one or more components in response to acoustical signals from a source of interference.

Abstract: An antenna for an implantable medical device (IMD) is provided including a monolithic structure derived from a plurality of discrete dielectric layers having an antenna embedded within the plurality of dielectric layers. The antenna includes antenna portions formed within different layers of the monolithic structure with at least one conductive via formed to extend through the dielectric layers in order to provide a conductive pathway between the portions of the antenna formed on different layers, such that an antenna is formed that extends between different vertical layers. The dielectric layers may comprise layers of ceramic material that can be co-fired together with the antenna to form a hermetically sealed monolithic antenna structure. The antenna embedded within the monolithic structure can be arranged to have a substantially spiral, helical, fractal, meandering or planer serpentine spiral shape.

Abstract: An antenna for an implantable medical device (IMD) is provided including a monolithic structure derived from a plurality of discrete dielectric layers having an antenna embedded within the monolithic structure. Superstrate dielectric layers formed above the antenna may provide improved matching gradient with the surrounding environment to mitigate energy reflection effects. A outermost biocompatible layer is positioned over the superstrates as an interface with the surrounding environment. A shielding layer is positioned under the antenna to provide electromagnetic shielding for the IMD circuitry. Substrate dielectric layers formed below the antenna may possess higher dielectric values to allow the distance between the antenna and ground shielding layer to be minimized. An electromagnetic bandgap layer may be positioned between the antenna and the shielding layer.
