Patent ID: 8100925

Claim:
A method for creating intussusception in a stomach comprising: transorally advancing a device to a position inside the stomach, the device having a proximal portion and a distal portion, the distal portion comprising an expandable member, the expandable member having a proximal end, distal end, inner surface, and outer surface, and defining a cavity therein to receive tissue; expanding the expandable member, such that the proximal end of the expanded expandable member defines a proximal end of the cavity; drawing stomach tissue through the proximal end of the cavity into a distal portion of the cavity of the expanded expandable member using suction to telescope a first region of stomach tissue into a second region of stomach tissue, thereby forming the intussusception and a stomach portion proximal to the intussusception and distal to a gastroesophageal junction; and securing the intussusception with one or more anchors, wherein fibrosis occurs so that the intussusception remains secured irrespective of the one or more anchors.
