ABSTRACT:
Liquid metal gallium-filled balloon catheter is connected to a source of heating power. An improved method of hyperthermia and ablation is made possible by ease of insertion and conformity to complex intracavitary geometry by liquid metal. Closeness of gallium melting point to body temperature makes insertion of solid gallium possible and subsequent melting after insertion. Method of balloon ablation of endometrium is described.
