Medical Devices Including Connector Enclosures with a Metallic Weld to a Can Housing Circuitry

摘要

Medical devices provide connector enclosures that have a metallic portion that has a metallic weld to a metallic portion of a can that houses medical circuitry. The connector enclosure may have a metallic base that receives the metallic weld to the can. The can may have an open top that is capped by the metallic base of the connector enclosure upon mounting the connector enclosure to the can, and the metallic weld to the base of the connector enclosure may create a hermetic seal for the can. The metallic base may provide feedthrough pin passageways where feedthrough pins are present within the connector enclosure and are exposed beyond the metallic base for connection to medical circuitry within the can. The connector enclosure may also include additional metal features where an enclosure for the lead connectors may have walls that are entirely metal.

主权项

1. A method of constructing a medical device, comprising:
providing a can that houses medical circuitry, at least an edge of the can being metallic; providing electrical connectors within the can and electrically connected to the medical circuitry; providing a connector enclosure that encloses lead connectors, the connector enclosure having a base and at least one wall that are metallic, the base and the at least one wall being welded together and defining a cavity, the connector enclosure including an opening to the cavity; providing lead connectors within the cavity and in alignment with the opening; providing electrical conductors that are electrically connected to the lead connectors within the cavity and that are electrically isolated from the metallic base and wall while being exposed outside of the base of the connector enclosure; placing the metallic edge of the can in contact with a metallic edge of the metallic base such that the electrical connectors within the can and the electrical conductors exposed outside the metallic base are in contact and are contained by a housing created by the contact of the can and the metallic base of the connector enclosure; and creating a metallic weld between the contact of the metallic edge of the can and the metallic base of the connector enclosure.
