Abstract
An implantable medical device includes a hermetically sealed housing that contains electronic circuitry. A feedthrough is disposed on an external surface of the housing. An antenna wire is disposed around the external surface of the housing. The antenna wire has one end connected to the feedthrough so that the antenna wire is in electric communication with at least a portion of the electronic circuitry. A heat shrink tube is sealingly disposed about substantially the entire external surface of the antenna wire to prevent fluids from contacting the antenna wire and thereby detuning the antenna wire. An antenna surround is disposed about the tube.
