Claims (3)
- 所定の基板上に形成され患者の視覚を形成する視覚神経系を構成する細胞又は組織を電気刺激するための複数の電極と、該電極に接続され電気刺激パルス信号を前記電極から出力させる制御手段と、を備える視覚再生補助装置において、
前記電極は所望する表面積を確保するために電極の表面に凹部を設けたことを特徴とする視覚再生補助装置。 - 請求項１の視覚再生補助装置において、前記凹部は前記電極の先端から底に向って略垂直方向に形成される少なくとも一つの孔部であることを特徴とする視覚再生補助装置。
- 請求項２の視覚再生補助装置において、
前記孔部は、前記電極の先端に形成された開口から前記基板に向かって円柱状に座繰られた孔部であり、
前記孔部の内径は前記電極の外径の２分の１未満に形成されると共に、前記孔部は前記電極に複数設けられることを特徴とする視覚再生補助装置。
