1. An implantable medical device configured for implant in a hole in a cranium of a patient, relative to a bone table corresponding to a surface of the cranium adjacent the hole, the implantable medical device comprising:
a can having an electrical-contact pad, the can characterized by a form factor having a perimeter edge defining a boundary of the can, and a recessed portion with an upper surface positioned to lie beneath the bone table when the can is placed in the hole, and that supports the electrical-contact pad;
a cover assembly having a plurality of ports, each of the plurality of ports configured to receive a connector end of a lead, the cover assembly configured to couple to the can and decouple from the can at the electrical-contact pad; and
a strain relief system comprising:
a lower strain relief defining a plurality of channels, wherein each of the plurality of channels is configured to receive a portion of a lead body and includes a curved portion that extends upward from a proximal end at or near the upper surface of the recessed portion to a distal end at the bone table, and
an upper strain relief configured to cover the plurality of channels of the lower strain relief.
