<p>A ceramic characterised in that it is a glass, glass-ceramic or sintered ceramic which is suitable for inducing localised heating in the presence of a radio frequency magnetic field, the field having a frequency sufficiently low that essentially only magnetic hysteresis heating may occur, and which has incorporated therein magnetic iron-containing crystals of such size, composition, concentration and magnetic properties to impart a coercive force of at least 200 oersteds to the material is disclosed.
<??>In general terms, the present invention is directed to a non-invasive tumour treatment modality which results in a reduction of tumour mass and may lead to complete eradication of a tumour. In another embodiment, the present method comprises localised magnetically-coupled, RF-induced hyperthermia mediated by a material which is non-toxic to and, preferably, compatible with animal tissue and has incorporated therewithin iron-containing crystals of such size, amount, composition and magnetic properties to impart a coercive force of at least 200 oersteds to the material, and wherein the RF magnetic field has a frequency preferably not in excess of 10 kilohertz. </p> |
