Gastric restriction devices with fillable chambers and ablation means for treating obesity

摘要

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.

主权项

1. 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, the skirt having a left edge, a right edge, a top edge with a first indentation located at the center of the top edge portion, and a bottom edge with a second indentation located at the center of the bottom edge, the skirt having a narrow surface located between the first indentation and the second indentation and a broad surface formed from the left edge connecting to the right edge, the narrow surface operable to envelop a lesser curvature of a stomach of a mammal and the broad surface operable to envelop a greater curvature of the stomach; a chamber attached to the interior surface of the skirt and capable of holding a fluid, the chamber configured to be positioned around the stomach so that the chamber covers a portion of the greater curvature of the stomach and a portion of the 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.
