In some examples, a battery assembly for an implantable medical device. The assembly includes a housing, an electrode stack comprising a plurality of electrode plates disposed inside the housing, and an intermediate member configured to align the electrode stack at a fixed position within the housing, the intermediate member comprising a plurality of side walls, and at least one protrusion disposed on an exterior surface of the side walls, wherein the at least one protrusion is in thermal contact with an interior surface of the housing.

Intermediate member with protrusions for medical device battery assemblies

Techniques for forming a header for an implantable medical device via a two-shot molding process are described. The two-shot molding processes may include a first molding step that creates a first-shot assembly and a second molding step that creates a second-shot assembly. The first-shot assembly may be formed to include one or more protrusions configured to interact with a second-shot mold and/or molding material in the second molding step. The second molding step may be configured to overmold the first-shot assembly. The header may include an attachment plate at least partially embedded in molding material and configured to be mechanically coupled to a body of the implantable medical device.
