A modular implantable medical device includes a plurality of modules that are at least partially encapsulated by an overmold. The modules may be connected by coupling modules, which may be flexible to provide for one or more degrees of relative intermodular motion. The overmold may also be flexible. In order to reduce relative intermodule motion to acceptable direction and/or ranges, the overmold may include one or more motion reduction elements.

At least one surface of an implantable medical device is concave along at least one axis such that it substantially conforms to a surface within a patient, such as the cranium, when it is implanted on that surface. In some embodiments, the surface of the implantable medical device substantially conforms to an arc with a radius that is between 4. 5 and 9. 5 centimeters, and is preferably approximately equal to 7 centimeters. In some embodiments, the implantable medical device comprises a plurality of interconnected modules, and an overmold that at least partially encapsulates each of the modules. In such embodiments, at least one surface of the overmold is concave along at least one axis. Further, each of the modules of such an implantable medical device may comprise a housing, and at least one surface of at least one of the housings may be concave along at least one axis.

An implantable active medical device is disclosed and includes a hermetically sealed housing defining a sealed housing interior, a power source and electronics in electrical communication and disposed within the sealed housing interior, and a lead connector projecting into the sealed housing interior. The lead connector includes a closed end, an open end, an outer surface, and an inner surface defining a lead aperture. The lead connector includes one or more electrically conducting contact rings spaced apart by electrically insulating rings. The one or more electrically conducting contact rings are in electrical communication with the electronics and the lead connector provides a hermetic seal between the lead connector outer surface and the lead connector inner surface.

In an implantable medical device having individual modules, a coupling module couples the modules to one another. The coupling module supports electrical and/or mechanical coupling of the modules. The coupling module may assume a variety of shapes or configurations. The various embodiments of the coupling module may offer the modules varying degrees of freedom of movement relative to one another.

A method of manufacturing a hermetic lead connector includes fixing an electrically insulating ring between an electrically conducting contact ring and an electrically conducting spacer ring to form a hermetic ring subassembly, and fixing a plurality of the hermetic ring subassemblies in axial alignment to form a hermetic lead connector. The hermetic lead connector includes an open end, an outer surface, and an inner surface defining a lead aperture. The hermetic lead connector provides a hermetic seal between the outer surface and the inner surface.

The disclosure is directed to a capacitive pressure sensor, and the assembly of a capacitive pressure sensor, that may be used within an implantable medical pump. In one example, a housing ferrule that encloses one capacitive plate and includes at least one protrusion for attaching a support structure of the capacitive plate. The at least one protrusion defines a smaller inner diameter as a reference point for securing the support structure while the ferrule provides a larger inner diameter to allow the support structure to tilt inside the ferrule to orient the capacitive plate into a desired plane. Despite manufacturing irregularities, the capacitive plate can be mounted in the desired plane parallel to another capacitive plate, a diaphragm, mounted to an edge of the ferrule. In another example, an assembly tool provides a stage to orient the capacitive plate and support structure within the ferrule at a desired depth.
