Heat intensifier and localizer for radiofrequency thermotherapy
First Claim
1. A sterile injectable mixture for injection into a tumor which intensifies and localizes radio frequency thermotherapy of the tumor, said mixture comprising the combination of finely ground manganese zinc ferrite means in an aqueous suspension, a surfactant, a chemotheraputic agent, an anesthetic agent and a thickening agent, said manganese zinc ferrite means comprising individual manganese and zinc complexed ferrite particles coated by microencapsulation with an inert plastic para-di-zylene.

Abstract
A sterile injectable mixture which intensifies and localizes radio frequency thermotherapy; the injectable mixture contains finely ground ferrite particles in a viscid aqueous suspension, the ferrite being matched for maximum radio frequency absorption at a specific frequency. A chemotherapeutic agent, a surfactant and a bioacceptable hydrophic colloid are also contained in the mixture.

12. A sterile injectable mixture for injection into a tumor which intensifies and localizes radio frequency thermotherapy, said mixture containing finely ground complexed manganese zinc ferrite particles in powder form, said complexed manganese zinc ferrite particles being at least two thirds iron and encapsulated in biologically inert plastic material in a viscid aqueous suspension, said complexed manganeses zinc ferrite particles being matched for maximum radio frequency absorption ranging from 13.56 mHz to about 27.12 mHz and substantially totally absorbing the energy of the radio frequency waves, said mixture further containing a chemotherapeutic agent, a surfactant and a bioacceptable hydrophillic colloid.
