Electrode assemblies for applying tumor treating fields (ttfields) to a subject’s body, with features that prevent the electrode assemblies from peeling away from the subject’s skin

Abstract

Electrode assemblies for applying Tumor Treating Fields (TTFields) to a subject’s body can employ a sheet of graphite to spread out the heat and electrical current over the surface of the electrode assembly. But because graphite does not stretch, normal movements of the subject’s body in certain anatomical locations can cause the electrode assemblies to peel away from the subject’s body. The electrode assemblies described herein are shaped and configured in ways that reduce this tendency to peel away from the subject’s body. This can be accomplished by configuring the sheet of graphite so that it has a main section and two protruding sections that extend from the main section into adjacent quadrants of a Cartesian coordinate system, with a gap disposed between the two protruding sections.
