    摘要: 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. 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.

    摘要: An improved design for subcutaneous monitors that addresses the problem caused by bubbles of air may remain in the pocket in which the device is implanted. As implantable monitors and their associated electrodes are reduced in size, these bubbles may in some cases cover one or both electrodes, interfering with sensing of the ECG signal. The invention addresses this problem by configuring the electrodes to increase the pressure of the electrodes against the tissue above the electrodes relative to the pressures exerted by the adjacent outer facing surfaces of the device.
