Abstract
A minimally invasive system and method for providing weight loss by inducing the feeling of satiety whereby an intragastric device is inserted into the gastric lumen via the esophagus and an external magnetic device is used as needed to magnetically attract the intragastric device towards the inner wall of the stomach and impart tactile stimulation sufficient to induce the feeling of satiety.
Claims19
A method of inducing a feeling of satiety comprising the steps of:
- transesophageally inserting a deployable intragastric device containing magnetic material into a stomach of a patient, wherein the intragastric device is not attached to a body part of the patient;
- and
- positioning an external magnet in close enough proximity to the intragastric device to create a sufficient magnetic pulling force between the external magnet and the intragastric device to move the intragastric device towards, and impart stimulating force upon, a stomach wall of the patient, wherein the patient positions the external magnet and the stimulating force is applied for a therapeutically sufficient period of time to induce satiety.
A satiety inducing system comprising:
- a transorally administered intragastric device comprising at least one type of magnetic material, at least one surface capable of deployment inside of a patient's stomach, wherein the intragastric device is equipped to impart tactile stimulation upon a stomach wall of the stomach, and wherein the intragastric device is not attached to a body part of the patient;
- and
- an external device positioned outside of a patient's body comprising a sufficient amount of magnetic material to attract the transorally administered intragastric device from outside the patient's body, wherein the external device is configured to be positioned by the patient by moving the magnetic material.
A method of inducing a feeling of satiety comprising the steps of:
- transesophageally inserting a deployable intragastric device containing magnetic material into a stomach of a patient, wherein after insertion the intragastric device is free floating in the stomach;
- and
- positioning an external magnet in close enough proximity to the intragastric device to create a sufficient magnetic pulling force between the external magnet and the intragastric device to move the intragastric device towards, and impart stimulating force upon, a stomach wall of the patient, wherein the patient positions the external magnet and the stimulating force is applied for a therapeutically sufficient period of time to induce satiety.
