Patent ID: 10918511

Abstract:
An intragastric balloon device including a deformable material is in an ingestible form for delivery to a stomach of a patient, expands in response to stimuli in the stomach, and degrades within a limited duration (such as 16 hours or some other value between 2 hours and 72 hours) to diminish to passable form in which remains of the intragastric balloon device are passable from the stomach. In an illustrative example, the deformable material is composed of silicone coated with parylene and encloses perfluoropentane fluid that transitions from liquid to gas due to stomach temperature to inflate the balloon in the stomach and occupy space in the stomach until a fuse of methacrylate erodes to unblock a vent conduit to permit escape of the perfluoropentane for deflating the balloon to diminish to passable form.
