Abstract
Abstract A method and article for medical diagnosis and/or treatment of body disorders, comprising a sleeve unit 10 insertable in a natural body vessel to isolate material flowing into the vessel from direct contact with the interior surface of the vessel. When applied to the treatment of obesity, the sleeve is disposed along a zone in the digestive tract 32 to interfere with the digestive or absorptive function of that zone and thereby reduce net caloric intake.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being disposed substantially entirely in the stomach.
Claim 2
Independent Claim
126 words
A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being disposed substantially entirely in the stomach.
Claim 3
Independent Claim
138 words
A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being anchored in position in said digestive tract by means extending through the digestive tract to the oral cavity.
Claim 4
Independent Claim
138 words
A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being anchored in position in said digestive tract by means extending through the digestive tract to the oral cavity.
Claim 5
Dependent Claim
21 words
A method as set forth in claim 2, wherein said sleeve is positioned in said digestive tract through the oral cavity.
Claim 6
Independent Claim
162 words
A method of controlling obesity, comprising the steps of positioning a sleeve impervious to digestive juices and normal foods in the digestive tract, arranging the sleeve in the digestive tract in such a manner that substantially all normally ingested food material passing naturally through the oral cavity and then passing through the digestive tract is caused to pass through the sleeve while being isolated from direct contact with the surrounding area of the interior walls of the digestive tract and body fluids secreted by such surrounding area interior walls such that natural absorption of food material in the digestive tract is impaired and a net caloric intake for a given quantity of ingested food is thereby reduced, said sleeve being passed through the oral cavity and other upper areas of the digestive tract in a compacted condition and being expanded along substantially its full axial length into sealing contact with at least a portion of said surrounding area of said interior walls.
Claim 7
Independent Claim
162 words
