This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.

Lead retention and sealing 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

An improved system and method for interconnecting an electrical device to a connector is provided. A connector assembly includes at least one connector block. The connector block may be of a type adapted to mechanically and electrically couple to an electrical lead, although any other type of connector for forming an electrical contact may be employed. The connector assembly further includes at least one weld plate. A conductor such as a wire is routed between the connector block and the weld plate and electrically coupled to both structures. The connector assembly is adapted to be fastened to a device housed within an enclosure, such as an implantable medical device residing within a can. A conductor extending from circuitry within the housing may be electrically coupled to the weld plate to thereby form an electrical connection between the circuitry and the connector block.

Connector module having internal weld plates

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

An implantable medical device comprising a housing, a capacitor, an electronics module and a substantially flat battery. The capacitor is disposed within the housing. The electronics module is electrically connected to the capacitor and similarly disposed within the housing. The electronics module generally defines opposing front and rear faces, and is positioned such that the rear face is adjacent a wall of the housing. Finally, the battery is electrically connected to the electronics module and is positioned over the electronics module such that the battery is adjacent the front face of the electronics module. With this configuration, an overall shape and size of the implantable medical device is optimized.
