Implantable medical devices including baseplates having separate bodies of material thereon

An implantable medical device, comprising:

• an enclosure;
• circuitry within the enclosure;
• a base plate attached to the enclosure, the base plate having a thickness;
• a connector assembly enclosure coupled to the base plate such that the base plate separates the enclosure and the connector assembly enclosure, wherein the thickness of the base plate is present in a direction of separation between the enclosure and the connector assembly enclosure;
• a body of material present between at least a portion of the base plate and at least a portion of the connector assembly enclosure such that the body of material extends through only a portion of the thickness of the base plate;
• a plurality of connectors present within the connector assembly enclosure;
• and
• a plurality of feedthrough pins, each feedthrough pin of the plurality of feedthrough pins being electrically connected to a corresponding connector of the plurality of connectors, each feedthrough pin being electrically coupled to the circuitry, wherein the body of material has a set of holes to provide a separate hole for each feedthrough pin of the plurality of feedthrough pins and wherein each feedthrough pin passes through a corresponding one of the holes of the body of material.

A method of constructing an implantable medical device, comprising:

• providing an enclosure;
• attaching a base plate to the enclosure, the base plate having a thickness;
• attaching a body of material to the base plate;
• coupling a connector assembly enclosure to the base plate such that at least a portion of the connector assembly enclosure covers the body of material and such that the base plate separates the enclosure and the connector assembly enclosure, wherein the thickness of the base plate is present in a direction of separation between the enclosure and the connector assembly enclosure and wherein the body of material extends through only a portion of the thickness of the base plate;
• placing circuitry within the enclosure;
• placing a plurality of connectors within the connector assembly enclosure;
• and
• electrically coupling each of the connectors of the plurality of connectors to corresponding feedthrough pins of a plurality of feedthrough pins, each feedthrough pin of the plurality of feedthrough pins being electrically coupled to the circuitry, wherein the body of material has a set of holes to provide a separate hole for each feedthrough pin of the plurality of feedthrough pins and wherein each feedthrough pin passes through a corresponding one of the holes of the body of material.
