Abstract

A device for inducing weight loss in a patient includes a tubular prosthesis self-expandable from a collapsed position in which the prosthesis has a first diameter to an expanded position in which the prosthesis has a second, larger, diameter. In a method for inducing weight loss, the prosthesis is placed in the collapsed position and inserted into a stomach of a patient. The prosthesis is allowed to self-expand from the collapsed position to the expanded position and into contact with the walls of the stomach, where it induces feelings of satiety and/or inhibits modulation of satiety-controlling factors such as Ghrelin.

Claims

1-109. -109. (canceled)

110. A method of treating a patient having an esophagus, a stomach, and an intestine, the method comprising the steps of:

passing in a distal direction a first implant through the esophagus and into the stomach;

coupling the first implant to tissue of the proximal stomach;

passing in a distal direction a second implant comprising an elongate sleeve having an upstream opening and a downstream opening;

coupling the second implant to the first implant with the upstream opening in the proximal stomach; and

positioning the downstream opening within the intestine.

111. The method of claim 110, wherein food ingested by the patient into the upstream opening into the sleeve, and flows from the sleeve into the intestine.

112. The method of claim 110, wherein the method includes coupling the second implant to the first implant after passing them through the esophagus.

113. The method of claim 112, wherein the method includes coupling the second implant to the first implant after coupling the first implant to tissue of the proximal stomach.

114. The method of claim 110, wherein the first implant is proportioned to restrict the rate at which food flows from the esophagus into the upstream opening.

115. The method of claim 110, wherein the first implant sleeve comprises a tapered tubular implant.

116. The method of claim 110, wherein the sleeve comprises a polymeric material.

117. The method according to claim 110 wherein the second implant is retained with the upstream opening in the gastro-esophageal junction of the stomach.

118. The method according to claim 110, further including coupling the first implant prosthesis to tissue of the gastro-esophageal junction.

119. The method according to claim 110, wherein the first implant includes opening, wherein food ingested by the patient flows into the opening of the first implant, from the first implant into the upstream opening into the sleeve, and flows from the sleeve into the intestine.
