Title:
INTRAGASTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/045482
Kind Code:
A3
Abstract:
An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track. The device may further incorporate tracking and visualization subcomponents, as well as pharmaceutical delivery subcomponents. In a preferred embodiment, a swallowable, intragastric volume-occupying device is provided comprising a compacted balloon 445 having therein a silicone head 441 with radioopacity ring 442, a silicone septum 443, an inoculation spacer 444, an inner container 446, and outer container 447.
