In this study, we investigated histological evaluation of the titanium mesh electrode that was used for a transcutaneous communication system using intrabody communication . The internal communication unit wearing the titanium mesh electrodes were placed on the internal wall of thoracic cavity, and after 4 weeks, the explanted titanium mesh electrodes were prepared using hematoxylin and eosin stain, and investigated by light microscopy. From the results, the porosities of the titanium mesh electrode were filled with connective tissue and inflammatory cells. Occasionally macrophages or foreign body giant cells were observed, mostly lying on one side of the titanium fibers. Stress inside the titanium mesh electrode by movement of the internal communication unit would cause the inflammatory response and it would retard healing tissue inside the titanium mesh electrode.
