Satiation pouches and methods of use
First Claim
1. A method of positioning a prosthetic device within a patient having an esophagus, a stomach, and a gastro-esophageal junction region, the method comprising the steps of:
- providing a prosthetic device having a proximal opening and an exit port, and a barrier on a proximal portion of the prosthetic device, the barrier having a central passage at least partially aligned with the proximal opening;
securing the prosthetic device within a patient by attaching the prosthetic device to tissue of the gastro-esophageal region of the patient, the prosthetic device oriented such that food ingested by the patient passes from the esophagus through the central passage and proximal opening into the interior of the prosthetic device; and
causing the barrier device to contact surrounding tissue, the barrier minimizing passage of food from the esophagus around the exterior of the prosthetic device and into the stomach.

Abstract
A pouch positionable within the gastro-esophageal region of a patient, such as for use as a satiation device, is described herein. The pouch includes a proximal opening and an exit port, and is positionable such that food ingested by the patient passes into the interior of the pouch and subsequently out the exit port. A barrier on the proximal portion of the pouch contacts surrounding tissue and thereby minimizes passage of food from the esophagus around the exterior of the pouch—thereby substantially preventing food from bypassing the pouch. In preferred forms of the embodiment, the barrier is adaptable in response to movement of the surrounding tissue to maintain contact between the barrier and the surrounding tissue.

14. A medical device positionable within a gastro-esophageal junction region of a patient having an esophagus and a stomach, the medical device comprising:
-
a prosthetic device having a proximal opening and an exit port, a proximal portion of the prosthetic device positionable within the gastro-esophageal junction region such that the proximal opening is in substantial alignment with the esophagus; and
a barrier attached to a proximal portion of the prosthetic device, the barrier defining a central passage at least partially aligned with the proximal opening of the prosthetic device, the barrier positioned to contact surrounding tissue substantially around its circumference when the prosthetic device is positioned within the gastro-esophageal junction region and to substantially maintain said contact despite movement of the surrounding tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of treating obesity in a patient having an esophagus, a stomach, and a gastro-esophageal junction region, the method comprising the steps of:
-
providing a pouch having a proximal opening and an exit port, the exit port being smaller than the proximal opening;
further providing a barrier having a central passage at least partially aligned with the proximal opening;
attaching the pouch to tissue of the gastro-esophageal region of the patient and causing the barrier device to contact tissue substantially around its circumference;
causing the patient to ingest food, the ingested food passing from the esophagus through the central passage and proximal opening into the interior of the pouch, the barrier minimizing passage of food from the esophagus around the exterior of the pouch. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of positioning a prosthetic device in a body cavity region defined by a circumferential wall, comprising the steps of:
-
providing a prosthetic device having a proximal opening and a distal opening, a passage extending between the proximal and distal openings, and a barrier on a proximal portion of the prosthetic device;
distending a circumferential wall of a body cavity region;
positioning the prosthetic device adjacent to the disentended circumferential wall; and
releasing the circumferential wall from the distended positioning, allowing the released wall to circumferentially contact the barrier, the barrier encouraging passage of substances through the passage by minimizing passage of body fluid around an exterior of the prosthetic device. - View Dependent Claims (37, 38, 39)

40. A method of positioning a prosthetic device in a body cavity region defined by a flared circumferential wall, comprising the steps of:
-
providing a prosthetic device having a proximal opening and a distal opening, a passage extending between the proximal and distal openings, and a barrier on a proximal portion of the prosthetic device;
positioning the barrier in a collapsed position;
positioning the prosthetic device with the barrier adjacent to the flared circumferential wall; and
releasing the barrier from the collapsed positioning, allowing the released barrier to circumferentially contact the flared circumferential wall, the barrier encouraging passage of substances through the passage by minimizing passage of body fluid around an exterior of the prosthetic device. - View Dependent Claims (41, 42)
