AI Technical Summary
Existing electrode assemblies for Tumor Treating Fields (TTFields) therapy suffer from hot spots due to uneven current distribution, limited current delivery, and skin irritation issues, primarily caused by hydrogel layers, which restrict the effectiveness of treatment and cause discomfort.
Incorporating an anisotropic material layer with directional thermal and electrical properties, such as pyrolytic graphite, to spread heat and current evenly across a larger surface area, minimizing hot spots and reducing skin irritation by using a conductive adhesive composite instead of hydrogel.
The anisotropic material layer allows for increased current delivery without exceeding safety temperature thresholds, enhancing treatment efficacy and reducing skin irritation, thus improving patient outcomes.
