Abstract
The invention relates to a gastric restraining device for treating excessive weight or obesity in mammals. The gastric restraining device includes an elastomeric sheet configured to be placed around a stomach of a mammal, an ablation device attached to the elastomeric sheet, the ablation device configured to emit energy toward an outer surface of the stomach when the elastomeric sheet is placed around the stomach, and an energy device coupled to the ablation device to generate the energy and to transfer the energy to the ablation device.
Claims20
A gastric restraining device for treating excessive weight or obesity in mammals, comprising:
- a skirt having an interior surface and an exterior surface having a surface area of at least 14 square centimeters;
- a chamber attached to the interior surface of the skirt and capable of holding a fluid, the chamber configured to be positioned around a stomach of a mammal so that the chamber covers a portion of a greater curvature of the stomach and a portion of a lesser curvature of the stomach;
- and
- a tube connected to the chamber for delivering the fluid into and out of the chamber to cause the chamber to expand and contract.
A gastric restraining device for treating excessive weight or obesity in mammals, comprising:
- an elastomeric sheet configured to be placed around a stomach of a mammal;
- an ablation device attached to the elastomeric sheet, the ablation device configured to emit energy toward an outer surface of the stomach when the elastomeric sheet is placed around the stomach;
- and
- an energy device coupled to the ablation device to generate the energy and to transfer the energy to the ablation device.
A method for treating excessive weight or obesity in mammals by gastric constriction or restraining, comprising:
- using an endoscopic device, inserting a bougie into the stomach adjacent to a lesser curvature of the stomach;
- tucking a portion of a greater curvature of the stomach toward the bougie which results in a first untucked stomach portion, a second untucked stomach portion, and a cavity between the first untucked stomach portion and the second untucked stomach portion;
- using a ligation device, inserting a ligature through the first untucked portion, the cavity, and the second untucked portion;
- and
- using the endoscopic device, removing the bougie from the stomach.
