Claim 0:
1. A method of using an implantable drug delivery device to deliver a drug to a living body, the implantable drug delivery device having a housing with at least one opening, a reservoir within the housing adapted to contain the drug, a temporary seal closing the at least one opening of the housing, and a heating element in thermal contact with the temporary seal, wherein the heating element is a tubular shaped ferrous heating element incorporated into the housing so as to be within the reservoir and in thermal contact with the temporary seal, the heating element generating heat in response to an oscillating magnetic field to at least partially melt the temporary seal and release the drug within the reservoir through the at least one opening of the housing, the method comprising:
placing the drug in the reservoir of the housing;
implanting the implantable drug delivery device in the living body; and
energizing the heating element in response to a reaction of the living body, the energizing step comprising generating the heat with the heating element in response to electrical current supplied to the heating element via application of the oscillating magnetic field to at least partially melt the temporary seal and release the drug within the reservoir through the at least one opening of the housing, the heating element sufficiently melting the temporary seal to release the drug into the living body through the at least one opening in the housing.
