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.

Implantable medical device header

An implantable medical device that includes a first molded portion and a second molded portion fusion bonded to the first molded portion at an interface. The molded portions each are based on a moldable plastic material. A component, e.g., an electrical component, for the implantable device has at least one section disposed at the fusion-bonded interface of the first molded portion and the second molded portion so that the electronic component is fusion bonded to one or both portions at the interface.
