Cranial implant

摘要

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.

主权项

1. An assembly of an implantable medical device configured for implantation within a recess formed in a cranium of the patient, the assembly comprising:
a top external surface located distally relative to a brain of the patient when the assembly 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 assembly is implanted within the recess, wherein the side external surface is configured to be adjacent to the cranium of the patient within the recess and not contact an external surface of the cranium, when the assembly is implanted within the recess, wherein the side external surface and the top external surface are oriented to define an acute angle at a corner of the assembly between the top external surface and the side external surface; 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 obtuse angle; a housing that forms a substantially sealed enclosure; circuitry within the substantially sealed enclosure, wherein the circuity is configured to at least one of control delivery of therapy to or monitor a patient via a lead; a feedthrough extending through the housing and configured to electrically connect to the lead outside of the housing; and a flexible tape interconnect within the housing and connected to the feedthrough, the flexible tape interconnect configured to electrically connect the circuitry within the housing to the lead via the feedthrough.
