摘要:
A method for attaching a capacitor to the feedthrough assembly of a medical device is provided. The capacitor includes a lower surface, and the feedthrough assembly includes a ferrule having a cavity therethrough for receiving at least one terminal pin. The feedthrough assembly is configured to be coupled to the medical device, and the cavity is configured to receive therein an insulating structure having an upper surface. The method comprises threading a first washer over the terminal pin, and placing a body of epoxy in contact with the first washer. The capacitor is positioned over the terminal pin such that the first washer and the body of epoxy are between the lower surface of the capacitor and the upper surface of the insulating structure. The body of epoxy is cured to couple the capacitor to the insulating structure. During curing, the body of epoxy is substantially confined between the upper surface and the lower surface by the ferrule, the insulating structure, the capacitor, and the first washer.

A method for attaching a capacitor to the feedthrough assembly of a medical device having a terminal pin comprises threading a first washer over the terminal pin, and placing a body of epoxy in contact with the first washer. The capacitor is positioned over the terminal pin such that the first washer and the body of epoxy are between the lower surface of the capacitor and a support surface. The body of epoxy is cured to couple the capacitor to the insulating structure. During curing, the body of epoxy is substantially confined between the upper surface and the lower surface by the ferrule, the insulating structure, the capacitor, and the first washer.

A method for coupling a capacitor to a feedthrough assembly that includes a ferrule and a terminal pin therethrough is provided. The method comprises dispensing an epoxy onto an outer surface of the feedthrough assembly. A capacitor, which has an opening therethrough for receiving the terminal pin and cooperates therewith to form a cavity, is placed over the ferrule to contact the epoxy. A weight is placed on the capacitor to position it with respect to the terminal pin, and the epoxy is cured.

A determination of an equivalent series resistance (ESR) effect for high frequency filtering performance of a filtered feed-through assembly is described. A low frequency signal is introduced to a filtered feed-through assembly. ESR limit of the filtered feed-through is determined based on the low frequency signal.

An electronic module assembly for an implantable medical device includes a non-conductive block having an opening for accepting a feedthrough conductor. The block has opposite first and second ends and opposite first and second sides. A bond pad is located on the first end of the block for electrical connection to a feedthrough conductor, and the bond pad extends to the first side of the block to provide an electrical connection region there.

A filtering capacitor feedthrough assembly for an implantable active medical device is disclosed. The filtering capacitor feedthrough assembly includes a capacitor having an aperture, the capacitor is electrically grounded to an electrically conductive feedthrough ferrule or housing of the implantable active medical device. A terminal pin extends into the aperture and an electrically conductive continuous coil is disposed within the aperture and between the terminal pin and the capacitor. The electrically conductive continuous coil mechanically secures and electrically couples the terminal pin to the capacitor.
