Stimulator for digestive organ

A stimulator for a digestive organ, the stimulator comprising:

• a case;
• a substrate member disposed in the case;
• and
• an electrode member connected to the substrate member and extending outwardly from the substrate member to and through a wall of the case and protruding outwardly from the case;
• wherein the electrode member has a shape of an elongated wire, the electrode member is formed to protrude by a length of 1 mm to 3 mm outwardly from a bottom surface of the case, and the electrode member is configured to penetrate into a layer of a digestive organ with said bottom surface resting upon a surface of the digestive organ;
• wherein the electrode member is configured to provide an electrical stimulation in a state of being inserted and fixed at a predetermined location within the digestive organ, said stimulator including at least one fixing element for fixing the stimulator at the predetermined location within the digestive organ,
• wherein the substrate member comprises:
• an upper substrate;
• and
• a lower substrate having a region separated from the upper substrate, and
• wherein the electrode member is connected to the lower substrate at a side of the lower substrate opposite to the upper substrate, so that said stimulator is minimally invasively insertable into a digestive organ using an endoscope, and
• the stimulator further comprising:
• a battery member disposed between the upper substrate and the lower substrate and electrically connected to the upper substrate and the lower substrate.
