Anatomically compliant antenna for implantable medical device
First Claim
1. An implantable medical device configured to be implanted in a patient, comprising:
- a housing having an edge, the housing configured for placement in a ferrule installed in a hole formed in the cranium of the patient;
an antenna feedthrough extending from the housing; and
an antenna coupled to the antenna feedthrough, the antenna formed of at least one wire arranged in a rectangular configuration having a length side and a width side, the antenna positioned relative to the housing such that;
1) the length side of the rectangular configuration is immediately adjacent to the edge of the housing and extends substantially parallel to and along the edge of the housing, and the width side of the rectangular configuration extends outward relative to the edge of the housing, and
2) upon placement of the housing in the ferrule, the rectangular configuration is positioned outside of the ferrule, adjacent a surface of the cranium, while remaining immediately adjacent to the edge of the housing and substantially parallel to the edge of the housing,wherein the antenna is configured so that at implant of the implantable medical device in the patient, the antenna is capable of being bent to conform to an anatomical contour of the patient and, upon being bent, is capable of retaining a bent shape.

Abstract
A flexible antenna is associated with an active implantable medical device to facilitate communication between the implantable medical device and an external component in the outside world via, for example, long range or far field telemetry. The flexibility of the antenna allows it to conform to the shape of the location at which it is situated, such as on the cranial bone of a patient for an antenna associated with a cranially implanted medical device. The conformability of the antenna helps to maintain the antenna in the desired shape and to maintain it in the desired location relative to implantable medical device and the patient and improves patient comfort.
