An apparatus and method for administering focused energy to a body using either a single energy applicator or multiple energy applicators to supply heat prior to, concurrently with and/or after delivery of a drug, gene and/or viral vector. A multi-modality treatment using a localized, focused and/or regional heating apparatus, which supplies heat to a defined area of a patients body. The apparatus is used heat is used to pretreat a specific body site, to activate thermoactivated drugs, genes, or viral vectors, and/or to deliver drugs, genes, or viral vectors to the specific body site. The heating apparatus is provided with one or more variable and adjustable probes and one or more delivery ports heat the specific treatment site and to deliver the thermoactivated drugs and genes to the specific treatment site. Each probe may optionally be provided with one or more temperature sensors to allow for the temperature in the specific treatment site and the surrounding tissue to be properly regulated. The use of the apparatus and method allow for the heat conditioning of a specific treatment site and for the delivery or activation of a drug, gene, or viral vector limited to only the specific treatment site, allowing for a more accurate treatment of diseased tissue without damaging healthy tissue. In addition, this method is uniquely used with non invasive technologies to help determine on a real time basis the completion of the treatment.
