First Claim
1. An implantable medical device configured to at least one of deliver therapy to or monitor a patient, and configured for implantation within a recess formed in a cranium of the patient, the implantable medical device comprising:
- a top external surface located distally relative to a brain of the patient when the implantable medical device is implanted within the recess;
a side external surface adjacent to the top external surface and located proximate to the brain relative to the top external surface when the implantable medical device is implanted within the recess,wherein the side external surface is configured to contact the cranium of the patient within the recess and not contact an external surface of the cranium, when the implantable medical device is implanted within the recess,wherein the side external surface and the top external surface are oriented to define an internal acute angle at a corner of the implantable medical device between the top external surface and the side external surface,wherein the corner of the implantable medical device between the top external surface and the side external surface is adjacent the recess formed in the cranium of the patient when the implantable medical device is implanted within the recess;
a bottom external surface that is adjacent to the side external surface and non-adjacent to the top external surface, wherein the side external surface and the bottom external surface are oriented to define an internal obtuse angle, wherein the bottom external surface is oriented to face a brain of the patient, when the implantable medical device is implanted within the recess;
a housing that forms a substantially sealed enclosure, wherein the housing includes at least part of the top external surface;
a stimulation engine within the substantially sealed enclosure; and
a connection module coupled to the housing on the top external surface, wherein the connection module is configured to receive at least one of a lead or a catheter, and the implantable medical device is configured to at least one of deliver therapy to or monitor the patient via the lead or catheter.

Abstract
Implantable medical devices (IMD) configured for implantation within a recess formed in a cranium of a patient, as well as associated methods, are described. In some embodiments, the IMD includes a top external surface and another adjacent external surface, e.g., a side surface, which are oriented with respect to each other to define an acute angle. A connection module for an electrical lead or catheter may be included on the top external surface. Embodiments of the invention may facilitate implantation of an IMD within a recess formed in the cranium of a patient at a location remote to an incision made in the scalp of the patient.
