First Claim
Patent Images
1. An intragastric balloon configured to be implanted transorally into a patient'"'"'s stomach to treat obesity, the intragastric balloon comprising:
- an inflatable hollow body, the body having a body volume,wherein, in an implanted state, the body includes;
an under-inflated central inflatable member filled partially with a fluid, anda plurality of outer wings in fluid communication with the central inflatable member, the outer wings constructed to transition between a floppy configuration and a stiff configuration when the under-inflated central inflatable member transitions between a relaxed configuration and a squeezed configuration when a compressive force is applied by the stomach to the central inflatable member,wherein the body is made of a material that permits the body to be compressed into a substantially linear transoral delivery configuration, and that will resist degradation over a period of at least six months within the stomach,wherein the central inflatable member and the outer wings define a single internal chamber, such that the fluid can flow freely within the internal chamber, the body being filled with the fluid having a fluid volume that is less than the body volume, the body being constructed to conform to the shape of the stomach.

3. An intragastric balloon configured to be implanted transorally into a patient'"'"'s stomach to treat obesity, the intragastric balloon comprising:
-
an inflatable hollow body, the body having a volume between about 300 mls and about 700 mls, which volume is substantially the same both before and after inflation of the body with a fluid, the fluid occupying less than the volume of the body, wherein the body is made of a material that permits the body to be compressed into a substantially linear transoral delivery configuration, and that will resist degradation over a period of at least six months within the stomach, wherein the body has a single internal chamber with three interconnected regions, such that the fluid can flow freely between each region, the inflatable body being under-inflated to conform to the shape of the stomach, wherein the three regions include, an under-inflated, central spherical inflatable member, a first elongated outer wing, and a second elongated outer wing diametrically opposite the first elongated outer wing such that the first and second outer wings extend from opposite poles of the central inflatable member. - View Dependent Claims (4, 5, 6)
