A printed circuit assembly (PCA) for coupling to an IMD feedthrough of an implantable medical device includes a PCB portion and an interposer. The IMD feedthrough has a support structure and a plurality of electrical contacts extending through the support structure. The PCB portion is configured to be arranged relative to the support structure of the IMD feedthrough and includes a plurality of electrical contacts. The interposer is secured to the PCB portion and includes a dielectric over-mold structure and a plurality of leads. Each lead is integrated with the dielectric over-mold structure and includes a weld pad and a solder pad. Each solder pads of the interposer is electrically coupled to a corresponding electrical contacts of the PCB portion to provide an alignment between one or more weld pads of the interposer and one or more corresponding electrical contacts of the IMD feedthrough.

A burr hole cover includes a cap or cap assembly and a retainer and is configured to be partially positioned within a burr hole formed in a patient. The retainer has a cap-receiving aperture; a plurality of grooves provided in the retainer and a plurality of cut-outs wherein each cut-out is provided at an end of each groove towards the outer perimeter of the retainer. A channel may be provided at an opposite end of each groove vertically-extending from the top to the bottom of the retainer to encourage a medical device segment to remain in a groove during installation of the burr hole cover. The burr hole cover may be used to secure segments of medical devices relative to a burr hole and to allow a range of lateral motion for the portion(s) of the medical device(s) extending proximally out of the corresponding groove.

A ferrule for removably retaining a self-contained implantable device within a cranial opening of a patient is set forth. The ferrule includes a shelf portion, a wall portion, and at least one supporting tab connected to the wall portion. The shelf portion has an inner surface and an outer surface. The inner surface of the shelf portion substantially conforms to an implantable device. The wall portion has an inner surface and an outer surface and encompasses the shelf portion. The inner surface of the wall portion substantially conforms to the implantable device and the outer surface of the wall portion substantially conforms to the cranial opening.

Ferrule for cranial implant

A ferrule for retaining an implantable device within a cranial opening of a patient is set forth. The ferrule includes a shelf portion, a wall portion, and at least one supporting tab connected to the wall portion. The shelf portion has an inner surface and an outer surface. The inner surface of the shelf portion substantially conforms to an implantable device. The wall portion has an inner surface and an outer surface and encompasses the shelf portion. The inner surface of the wall portion substantially conforms to the implantable device and the outer surface of the wall portion substantially conforms to the cranial opening.

Disclosed is a means and method for placing an implantable neurostimulator control module into a place in the cranium where cranial bone has been removed. The method for accomplishing this cranial implantation is by first removing a patient's hair over the site of the implant, then cutting the scalp at that site and pulling it back to expose the cranium. A neurosurgeon would then remove a portion of the cranial bone to accept a control module to be implanted within that hole. The control module would then be placed into that hole. It is also conceived that the control module would be fixed in place by the use of one or more attachment devices such as a multiplicity of bone screws placed through holes in one or more flanges that extend over the cranium beyond the control module. The implantation could also include a fairing placed around the control module to provide a smooth contour under the patient's scalp. Also described is a spacer shim placed under the flange(s) to adjust the position of the control module so that its bottom surface does not put pressure on the dura mater lying directly over the brain tissue at the bottom of the hole. It is also envisioned that a resorbable disk could be placed under the bottom surface of the control module to further protect the brain and/or to elute an anti-biotic or anti-inflammatory substance to reduce the possibility of infection and/or inflammation.
