Mechanical heartburn and reflux treatment
First Claim
Patent Images
1. A heartburn and reflux disease treatment comprising:
- an adjustable non-inflatable restriction device adapted to be implanted in a patient having heartburn and reflux disease to engage the esophagus or the stomach close to the cardia without forming an upper pouch of the stomach that substantially accumulates food to form a restricted cross-sectional area of the food passageway in the stomach or esophagus, said restriction device being designed to work like an artificial sphincter to allow food to readily pass through the passageway, and a post-operation adjustment device for mechanically non-invasively adjusting said restriction device to change the size of the cross-sectional area sufficiently so as to substantially prevent regurgitation of stomach acids or foods into the patient'"'"'s esophagus.

Abstract
A heartburn and reflux disease treatment apparatus includes an adjustable restriction device implanted in a patient and engaging the stomach close to the cardia or engaging the esophagus to form a restricted cross-sectional area of the food passageway in the stomach or esophagus, and a post-operation non-invasive adjustment device for mechanically adjusting the restriction device to change the cross-sectional area of the passageway. By using a wireless remote control the patient can control the adjustment device, whereby the restriction device works like an artificial sphincter.

89. A method for treating heartburn and reflux disease, comprising:
-
(a) surgically implanting in the abdomen of a patient suffering from heartburn and reflux disease an adjustable non-inflatable restriction device which forms a food passageway having a restricted cross-sectional area in the esophagus or in the stomach close to the cardia, and (b) in a non-invasive procedure, mechanically adjusting the restriction device to change the size of the cross-sectional area of the food passageway.

90. A surgical method for laparoscopically implanting an adjustable restriction device of a heartburn and reflux disease treatment apparatus for forming a food passageway having a restricted cross-sectional area in the esophagus or stomach immediately close to the cardia, the method comprising:
-
(a) insufflating the abdomen of the patient to form a pneumoperitoneum;
(b) introducing at least one laparoscopic trocar into the abdomen;
(c) using a dissecting tool inserted through the laparoscopic trocar, dissecting the region of the esophagus or stomach adjacent or above the bursa omentalis;
(d) introducing the restriction device into the abdomen and applying the restriction device on the esophagus or stomach; and
(e) post-operatively adjusting the restriction device in a non-invasive procedure to change the cross-sectional area of the food passageway.

91. A heartburn and reflux disease treatment apparatus, comprising:
-
an adjustable non-inflatable restriction device adapted to be implanted in a patient having heartburn and reflux disease to engage the esophagus or the stomach close to the cardia without forming an upper pouch of the stomach that substantially accumulates food to form a restricted food passageway in the stomach or esophagus, said restriction device being designed to work like an artificial sphincter to allow food to readily pass through the passageway and prevent regurgitation of stomach acids or foods into the patient'"'"'s esophagus, and a holding device adapted to be implanted in the patient to hold the esophagus or stomach in a position where the left and right crus muscles are located, to prevent the region of the cardia from moving through the diaphragm muscle.
