ABSTRACT:
An implantable medical device having a hermetic canister a battery positioned within the hermetic canister; a pulse generator system positioned within the hermetic canister and electrically coupled to the battery; a receiver positioned within the hermetic canister and electrically coupled to the battery and the pulse generator system; a transmitter positioned within the hermetic canister and electrically coupled to the battery and the pulse generator system; and an antenna positioned outside the hermetic canister and coupled to the pulse generator by a feedthrough. The antenna is constructed of a series of planar windings enclosed by an enclosure; each winding is between 1-100 microns wide, wherein each winding is between 1-1000 microns thick and wherein each winding is spaced apart from each of the other windings between 1-100 microns. In the preferred embodiment the antenna has a closely spaced concentric winding of a conductive material, preferably gold, the winding having 30 turns, wherein is conductive material 25 microns wide, 100 microns thick, and each winding is spaced apart from each of the other turns by 20 microns.
