An implantable medical device (IMD) having a hermetic housing formed from a case and a cover each having an exterior surface and an interior surface. An IMD component is mounted to the interior surface of the cover and has an electrical contact. A hybrid circuit is assembled in the case. The IMD component electrical contact is electrically coupled to the to the hybrid circuit assembled in the case.

Assembly method for implantable medical device

A terminal platform comprising a first terminal block securable to a housing of the battery, a second terminal block configured to electrically connect to a terminal wire of the battery, and an insulating support electrically isolating the second terminal block from the first terminal block.

Terminal platforms for batteries in implantable medical devices

Methods and apparatus for an implantable medical device having a connector module that is welded to a housing. The apparatus comprises an implantable medical device that includes a housing and a connector module. The connector module includes an embedded fastener bracket with one or more weld tabs that are welded to the housing.

Welded connector attachment

In general, the invention is directed to an implantable medical device assembly having a more space-efficient housing and components, as well as processes for assembling the implantable medical device with reduced assembly cost and less complexity. The implantable medical device may incorporate a battery, capacitor, circuit assembly, feedthrough assembly, and interconnect assembly with respective electrical terminals. This configuration permits the use of automated electronic module assembly techniques such as parallel gap or ribbon bond welding to electrically connect the terminals. A feedthrough assembly may present a set of terminals adjacent a corresponding set of circuit terminals, also enabling the use of automated welding techniques.

Implantable medical device assembly and manufacturing method

The invention discloses a subcutaneous electrode array or SEA for use in medical devices. The arrangement provides an enhanced capability for detecting and gathering electrical cardiac signals via the array of relatively closely spaced subcutaneous electrodes. Further, switching circuits, signal processors and memory to process electric cardiac signals are implemented to enable a leadless orientation-insensitive SEA scheme for receiving the electrical signal from the heart. The SEA is distributed over the perimeter of the implanted medical device and includes a non-conductive surround shroud of biocompatible material. The surround shroud is placed around the periphery of the case of the implanted medical device. Various configurations of recesses, each of which contain individual electrodes, are implemented to provide an enhanced signal to noise ratio for improved signal quality.
