Aspects of the present disclosure are directed toward apparatuses, systems, and methods that may comprise a medical device having a header, a core assembly, and a scaffold assembly. The scaffold assembly may be configured to interface with the core assembly and position and support one or more circuit component relative to one or more other circuit components.

Header core fixation design for an IMD

An encapsulated filtered feedthrough assembly for an implantable medical device including a ferrule, an electrical insulator coupled to the ferrule, a printed circuit board (PCB), a feedthrough conductor extending through the electrical insulator and the PCB, and a capacitor coupled to the PCB. The encapsulated filtered feedthrough assembly can include a mold defining an opening and located with respect to the printed circuit board such that at least a portion of the capacitor is positioned within the opening. A first non-conductive material can underfill the capacitor and a second non-conductive material can be backfilled into the mold to encapsulate the capacitor.

Method of making an encapsulated filtered feedthrough for an implantable medical device

A filtered feedthrough assembly for an implantable medical device comprises a ferrule, an electrical insulator coupled to the ferrule by a connection element, a plurality of feedthrough conductors extending through the electrical insulator, a printed circuit board (PCB), and plurality of capacitors. The PCB is coupled to the ferrule or the electrical insulator, and includes one or more ground layers and a plurality of vias. The connection element is electrically coupled to the ground layer through the vias. The capacitor has a ground terminal electrically coupled to the ground layer through at least one of the vias, and a conductor terminal electrically coupled to the feedthrough conductor.

Encapsulated filtered feedthrough for implantable medical devices

A filtered feedthrough assembly for an implantable medical device includes a ferrule, an electrical insulator coupled to the ferrule by a connection element, a plurality of feedthrough conductors extending through the electrical insulator, a printed circuit board (PCB), and a plurality of capacitors. The PCB is coupled to the ferrule or the electrical insulator, and includes one or more ground layers and a plurality of vias. The connection element is electrically coupled to the ground layer through the vias. The capacitor has a ground terminal electrically coupled to the ground layer through at least one of the vias, and a conductor terminal electrically coupled to the feedthrough conductor.

A ferrule for an implantable medical device (IMD) can employ stamped metal portion including an electrically-conductive ferrule portion. The stamped ferrule portion can be affixed to a wall of a housing of the IMD. The resulting ferrule can provide cost savings or higher production throughput over a ferrule employing machined ferrule portion.

Ferrule for implantable medical device

A feedthrough assembly includes a metallic ferrule, an insulator mounted within the ferrule, a plurality of feedthrough wires mounted within and extending through the insulator, and a ground wire directly attached to the ferrule, wherein the ground wire does not pass through or alongside the insulator.

Feedthrough assembly for an implantable device

A technique for connecting a first circuit board to a second circuit board includes aligning appropriate apertures in the circuit boards and forming a solder joint through the aligned apertures. In one application, the techniques of the present invention are used to connect circuit boards of an implantable medical device, such as a cardiac rhythm management device.
