System, system devices, and methods for regulating nutrient absorption and caloric intake

摘要

A system ( 100 ) for regulating absorption and caloric intake can include an elongated tube ( 110 ) having a stomach portion ( 114 ) and a lower intestine portion ( 116 ) where the elongated tube defines a passage ( 114 ) to guide ingested material through the stomach ( 102 ) and through a portion of the small intestine ( 104 ). The system also includes a non-invasive stomach stricture device ( 150 ) having a clamping structure ( 152 ) for regulating the rate of flow of ingested material through the elongated tube where the clamping structure reduces the capacity of the passage by clamping a portion of the elongated tube through the exterior of the stomach.
