Title:
INTRAGASTRIC DEVICE FOR TREATING OBESITY
Document Type and Number:
WIPO Patent Application WO/2011/159271
Kind Code:
A1
Abstract:
The present invention is directed toward an intragastric device used to treat obesity that includes a wire mesh structure capable of changing from a compressed pre-deployment shape to an expanded post-deployment shape with a greatly increased volume. The post-deployment shape contains a light weight at the top and a heavier weight at the bottom to ensure proper positioning within the stomach. In the post-deployment shape, the device contains larger spaces in the upper portion and smaller spaces in the lower portion to sequester food and delay gastric emptying. Alternatively, the device can be enveloped by a membrane containing larger holes at the top and smaller holes at the bottom to sequester food and delay gastric emptying. The device has a dynamic weight where the weight of the device in the pre-feeding stage is less than the weight of the device in feeding or post-feeding stage.
