Abstract
When a patient is fitted with an external gastrostomy connection to the stomach, ingested food can be removed through the gastrostomy connection using a pump-based or siphon-based system to achieve weight loss. The process of removing ingested food can be improved by alternating the infusion of liquid into the stomach with the removal of material from the stomach. Optionally, stomach acid may be captured and returned to the stomach. Optionally, nutritional supplements or medicines may be added to the infused liquid. Optionally, a flush mount connectorized system with a built in valve may be used to simplify the interface with the gastrostomy hardware that remains installed in the patient. Optionally, the system may be configured to disable itself from further use after a triggering event (e.g., the passage of time or a predetermined number of uses) has occurred.
