This invention describes unique treatment methods and innovative articles that can be placed in a human or animal body to enable controlled destruction of diseased tissue. The methods include destruction of diseased cells and tissues by magnetically controlled motion and an externally controllable drug delivery process with a capability to start and stop the drug delivery at any time, for any duration. This invention provides two approaches to diseased cell destruction, (1) magneto-mechanical disturbance of cell structure (e.g. cancer cells) for cell lysis and (2) magnetically activated drug release at local regions (e.g. tumors) from a magnetic-particle-containing drug reservoir. The invention also provides combinations of both the above treatments for dual therapy. It further combines one or both of the treatments with magnetic hyperthermia for multifunctional cell destruction therapy. The approaches can be combined with magnetic MRI for monitoring the accuracy of placement as well as for following up the cancer destruction progress and appropriate reprogramming of the magneto-mechanical therapy and remote-controlled drug release.

The Low Temperature Hyperthermia System illuminates nano-particles, which are implanted in a living organism at the locus of the cancer or into the cancer cells, with a precisely determined energy field. This energy field ensures that the optimal cancer cell and cancer stem cell destruction temperature of 42° C. is not exceeded in the tissue, which minimizes the release of Heat Shock Proteins and cancer stem cells. The Low Temperature Hyperthermia System uses specially designed nano-particles that exhibit a specific temperature rise in a given illumination energy field and then have no further temperature rise even if the applied illumination energy field increases beyond the optimal level. Alternatively, the nano-particles exhibit a tightly controlled temperature rise based on a pre-determined illumination energy field strength. This innovative approach can also use radiation and / or chemotherapy in conjunction with the nano-particle illumination to kill the majority of the cancer cells.
