Abstract
In one aspect, a gastric balloon structure includes multiple isolated non-concentric inflatable chambers and a valve system for introducing fluid into each chamber, where the structure assumes, upon inflating, a curved shape conforming to a natural three-dimensional kidney shape of the gastric cavity.
Claims22
(canceled)
An obesity treatment apparatus comprising:
- at least two expandable balloons, wherein
- each balloon of the at least two expandable balloons comprises
- an inflation valve for inflating the respective balloon with one or more gasses, and
- a wall comprising at least two layers, wherein a first layer of the at least two layers includes an elastic material,
- the obesity treatment apparatus is configured for delivery via an esophagus of a patient in an uninflated state and inflation via an inflation catheter while situated in a stomach of the patient, and
- upon inflation, each balloon of the at least two expandable balloons is configured to occupy a respective volume in the stomach of the patient;
- wherein, after inflating each expandable balloon with the one or more gasses,
- the obesity treatment apparatus floats freely within the stomach of the patient without exerting pressure at any point in the stomach sufficient to cause ulceration, and
- the at least two expandable balloons arrange along a curved shape conforming to a natural three-dimensional kidney shape of the stomach such that the at least two expandable balloons align against greater or lesser curvatures of the stomach.
6 more elements
A space-occupying balloon system for obesity treatment, comprising:
- two or more inflatable gastric balloons, each balloon of the two or more inflatable gastric balloons comprising
- a wall including two or more layers, wherein a first layer of the two or more layers is formed from an elastic material, and
- a respective inflation lumen, wherein,
- prior to the inflation via the inflation lumen, each balloon of the two or more inflatable gastric balloons has a major dimension no larger than two centimeters, and
- after the inflation, the two or more inflatable gastric balloons arrange along a generally kidney shaped curve to align against the greater or lesser curvatures of the gastric cavity of a patient;
- wherein the space-occupying balloon system is configured for delivery via an esophagus of the patient and inflation with at least one gas after placement within the gastric cavity of the patient;
- and
- wherein each balloon of the two or more inflatable gastric balloons is released after inflation to float untethered within the gastric cavity of the patient.
5 more elements
An obesity treatment apparatus, comprising:
- at least two expandable balloons, each balloon of the at least two expandable balloons comprising
- a means for receiving and retaining one or more gasses delivered via an inflation catheter from an external pressurized fluid source, and
- a wall including two or more layers, wherein a first layer of the two or more layers is formed from an elastic material;
- and
- a means for conforming the obesity treatment apparatus, in an inflated state, to a natural three-dimensional kidney shape of a stomach of a patient;
- wherein the obesity treatment apparatus is configured for delivery via an esophagus of a patient in an uninflated state, wherein,
- upon inflation, each balloon of the at least two expandable balloons is configured to occupy a respective volume in the stomach of the patient, wherein
- each balloon of the at least two expandable balloons is filled with a same one or more gasses, and
- after inflation, the obesity treatment apparatus floats freely within the stomach of the patient without exerting pressure at any point in the stomach sufficient to cause ulceration, wherein
- the one or more gasses of the external pressurized fluid source are selected to provide buoyancy to the obesity treatment apparatus within the stomach.
