SYSTEMS AND METHODS FOR REMOVING INGESTED MATERIAL FROM A STOMACH
First Claim
1. A method of removing ingested food from a patient'"'"'s stomach via a gastrostomy tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach, the method comprising the steps of:
- (a) siphoning a first portion of the ingested food out of the patient'"'"'s stomach via the gastrostomy tube;
(b) infusing liquid into the patient'"'"'s stomach via the gastrostomy tube; and
(c) siphoning at least some of the infused liquid out of the patient'"'"'s stomach via the gastrostomy tube, together with a second portion of the ingested food.

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.

3. An apparatus for removing food from a patient'"'"'s stomach via a gastrostomy tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach, the apparatus comprising:
-
a connector configured to connect to a proximal end of the gastrostomy tube with a fluid-tight connection; a first fluid path provided between the connector and a drain port, configured to permit siphoning or pumping food from the patient'"'"'s stomach out to the drain port; a second fluid path provided between the connector and an input port, configured to permit infusion of liquid from the input port into the patient'"'"'s stomach; and a fluid circuit configured to alternately (a) open the first fluid path during a first interval of time to permit siphoning or pumping food out of the patient'"'"'s stomach and (b) open the second fluid path during a second interval of time to permit infusion of the liquid in the reservoir into the patient'"'"'s stomach. - View Dependent Claims (4, 5, 6, 7)
