1. An implantable medical device, comprising:
an implant body;
an induction coil extending from the implant body;
a biocompatible overmolding encapsulating the implant body and the induction coil, wherein the biocompatible overmolding defines an aperture within an area bounded by the induction coil, and wherein the aperture comprises a first end having a first diameter and a second end having a second diameter; and
an implantable magnet assembly comprising an implantable magnet, wherein at least a portion of the implantable magnet assembly is configured to be positioned in the aperture, and the at least a portion of the implantable magnet assembly positioned in the aperture and extending from the first end of the aperture to the second end of the aperture comprises a greater diameter than the first diameter and the second diameter of the aperture to provide an interference fit with the aperture.
