Implantable medical devices and related connector enclosure assemblies utilizing conductors electrically coupled to feedthrough pins

摘要

Implantable medical devices include connector enclosure assemblies that utilize conductors electrically coupled to feedthrough pins that extend into a can where electrical circuitry is housed. The conductors may be coupled to the feedthrough pins and to capacitor plates within a filter capacitor by an electrically conductive bonding material and as a single bonding event during manufacturing. The base plate of the connector enclosure assembly may also include a ground pin. Ground capacitor plates may be present at a ground aperture of the filter capacitor where the ground pin passes through so that the ground pin, a ground conductor, and the ground capacitor plate may be coupled. A protective cover may be provided for the connector enclosure assembly to enclose the conductors intended to extend into the can prior to the assembly being joined to the can. Conductors may be attached to a common tab that is subsequently removed.

主权项

1. An implantable medical device, comprising:
a connector enclosure including a base plate having an aperture, the connector enclosure housing at least one electrical connector; a can coupled to the base plate, the can housing electrical circuitry; a filter capacitor coupled to the base plate, the filter capacitor having an aperture and having capacitor forming plates including a ground plate, the ground plate being electrically coupled to the can; a feedthrough pin electrically coupled to the electrical connector within the connector enclosure, the feedthrough pin extending through the aperture in the base plate and being present in the vicinity of the aperture in the filter capacitor; a conductor with a first end being present in the vicinity of the aperture within the filter capacitor and with a second end extending into the can and electrically coupled to the electrical circuitry; and a body of electrically conductive bonding material being present within the aperture of the filter capacitor and creating an electrically conductive bond among the conductor, the feedthrough pin, and at least one of the capacitor forming plates other than the ground plate.
