Fixation of intraluminal device

An intraluminal device adapted to be deployed at the gastroesophageal (GE) region of a recipient, comprising:

• a wall defining a cardiac portion that is configured to the size and shape of the cardiac portion of the stomach, an esophageal portion that is configured to the size and shape of a portion of the esophagus and a connector connected with said esophageal portion and said cardiac portion, wherein said connector comprises a plurality of elongated members configured to pass through the GE junction;
• a fixation system configured to resist distal migration of said wall, said fixation system comprising short-term fixation and long-term fixation;
• said long-term fixation comprising a characteristic of said wall that is configured to facilitate tissue ingrowth;
• said short-term fixation configured to at least temporarily resist distal migration of said wall while tissue grows to said wall as said characteristic;
• and
• said long-term fixation and said short-term fixation being at least partially at said connector.

A method of fixation of an intraluminal device to resist distal migration in a mammalian lumen or hollow organ that is subject to peristalsis, the intraluminal device comprising spaced apart wall portions connected with a connector, wherein said wall portions are configured to the size and shape of a portion of the lumen or hollow organ and said connector is configured to be positioned against a wall of the lumen or hollow organ, said method comprising:

• positioning the intraluminal device in a mammalian lumen or hollow organ that is subject to peristalsis;
• fixing said device in the lumen or hollow organ against distal migration, wherein tissue tissue lining the lumen or hollow organ bridges over said connector;
• and
• explanting the device after tissue bridges over the connector including separating the connector from at least one of said wall portions and withdrawing the connector axially from the tissue bridging over the connector.

A method of fixation of an intraluminal device at the gastroesophageal (GE) region of a recipient to resist distal migration, the device having a wall defining a cardiac portion that is configured to the size and shape of the cardiac portion of the stomach, an esophageal portion that is configured to the size and shape of a portion of the esophagus and a connector connecting said esophageal portion and said cardiac portion, said method comprising:

• positioning the device at the GE region wherein tissue will grow to the wall to provide long-term fixation of the wall to the GE region of the recipient to resist distal migration;
• temporarily fixing the device at the GE region to resist distal migration while tissue grows to the wall;
• and
• wherein the temporarily fixing and the long-term fixation both at least partially occur at the connector.
