Claim 21:
22. 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 comprises a third diameter that is greater than the first diameter and the second diameter of the aperture to provide an interference fit with the aperture,
wherein the at least a portion of the implantable magnet assembly includes a circumferential channel formed into a coupling section of the implantable magnet assembly to provide a first edge and a second edge of the coupling section, and wherein the first edge and the second edge extend radially outward from the circumferential channel,
wherein the first edge and the second edge of the coupling section are configured to capture opposite sides of the biocompatible overmolding to position the at least a portion of the implantable magnet assembly within the aperture.
