Intragastric device

An intragastric balloon system, comprising:

• a capsule configured to be swallowable by a patient by normal peristalsis and to degrade in a gastric environment;
• a balloon compacted and contained within the capsule, the balloon including an outer surface, an inner surface, an interior cavity, a fill valve, and a release valve, wherein the fill valve and the release valve are separate valves;
• and
• a visualization material imbedded in the outer surface of the balloon, the visualization material being able to be seen using a noninvasive imaging technique when the balloon is in an inflated, deployed state;
• wherein the fill valve is a self-sealing valve that is configured to self-seal after a catheter is detached from the fill valve;
• wherein at least a degradable portion of the release valve is configured to degrade in an internal environment of the interior cavity of the balloon when a liquid is in the interior cavity of the balloon and in response to the liquid being in contact with the degradable portion of the release valve;
• wherein when the liquid is in the interior cavity of the balloon, the degradable portion of the release valve is configured to be degraded by contact with the liquid such that the degradation process opens the release valve to allow the liquid to travel from the interior cavity of the balloon into the gastric environment thereby deflating the balloon;
• and
• wherein the release valve comprises a seam where at least two portions of the balloon are joined together.
