Abstract: An assembly is provided for an implantable medical lead. The assembly includes a first lead body comprising one or more electrical leads, and a hermetic encasement. The encasement comprises a housing having first and second openings and interior walls, an interior space defined by the interior walls, an electronic network housed within the interior space, and a circuit board extending through the first and second openings. The circuit board comprises a plurality of layers into which the electronic network is at least partially integrated, a first set of one or more terminals electrically coupling the electronic network to the first lead body, and a second set of one or more terminals electrically coupled to the electronic network for external electrical engagement.

Abstract: An implantable pacemaker is provided with cardiac depolarization sensing electrodes welded into the case along a peripheral edge surface thereof. The electrodes are coupled to signal processing circuitry within the case to provide leadless acquisition of electrocardiographic data for telemetry to a programmer. Each electrode is a thin film, multilayer ceramic structure mounted in a welding ring. Each electrode is substantially flat and is disposed within a recess in the peripheral edge surface of the case. Each electrode is a sandwich structure comprising a thin film layer, first and second ceramic layers, and a ground plane layer between the ceramic layers.

Abstract: A subcutaneous electrode is structured to acquire electrocardiographic data and waveform tracings from an implanted pacemaker without the need for or use of surface (skin) electrodes. Thin film electrodes disposed on a top surface of a feedthrough are adapted to connect into an assembly at the peripheral edge of the implantable device. Each of the electrodes comprise an integral element of a subcutaneous electrode array or SEA which detects cardiac depolarizations that are communicable and displayable by a portable device programmer. The thin film electrode is a complete functional component with a hermetically attached weld ring adapted for direct welding into the implanted device casing. The distribution and dispersion of the electrodes around the perimeter of the pacemaker provide a maximum and equidistance setting of electrode pairs for either three or four preferred electrode configurations.
