An apparatus for treating obesity in a human or animal mammal patient. The apparatus comprising a first volume filling device segment and a second volume filling device segment. The first and second volume filling device segments are adapted to be assembled into an implantable volume filling device of a controlled size. Each one of the first and second volume filling device segment comprises at least one interconnecting structure. The interconnecting structure of the second volume filling device segment is adapted to be formed fitted, such that the first and second volume filling device segment can be assembled into the volume filling device. The assembled volume filling device is adapted to be at least substantially invaginated by a stomach wall portion of a patient, with the outer surface of the device resting against the stomach wall, such that the volume of the food cavity is reduced in size.

A surgical weight loss procedure to reduce stomach volume is provided. The procedure involves gathering together a quantity of stomach tissue and securing this tissue together in a gathered position, which can reduce the volume of the stomach. This reduced stomach volume allows a patient to feel satiated with a much smaller amount of food, leading to weight loss.

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be assembled movement restriction device of a controlled size. The assembled movement restriction device can at least partly be invaginated by a patient's stomach fundus wall. A substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient's diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, to thereby prevent the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen.

The invention relates surgical abdominal methods of treating obesity in a patient by implanting a volume filling device that, when implanted in a patient, reduces the food cavity in size by a volume substantially exceeding the volume of the volume filling device. Also disclosed is a laparoscopic instrument for providing a volume filling device to be invaginated in the stomach wall of a human patient to treat obesity.

An apparatus for treating obesity comprises a volume filling device formed by at least two segments and is provided and following implantation, the device is placed resting against the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patients appetite.

An obesity treatment apparatus comprises at least one operable stretching device implantable in an obese patient and adapted to stretch a portion of the patient's stomach wall, and an operation device for operating the stretching device when implanted to stretch the stomach wall portion such that satiety is created.

A post gastrectomy anchoring procedure comprises anchoring a sleeve created by a gastrectomy to tissue structure that can better immobilize the sleeve to reduce complications relating to mobility of the sleeve. Namely, the anchoring procedure secures one or more portions of the sleeve to retroperitoneal fat of a patient. One or more bindings attach the sleeve to the retroperitoneal fat. The bindings can be installed to hold the sleeve in a bent or other shape, such as to mimic the natural shape of the patient's stomach and maintain an opening in the angularis of the sleeve.

A gastric vest system for treating excessive weight or obesity in mammals. The gastric vest system may include a trapezoidal-shaped vest having a left edge, a right edge, an upper indentation, and a lower indentation, and the trapezoidal-shaped vest is configured to be wrapped around a stomach or a modified stomach of a mammal to cover a lesser curvature and a greater curvature of the stomach or the modified stomach.

An obesity treatment apparatus comprises at least one operable stretching device (10) implantable in an obese patient and adapted to stretch a portion (12a) of the patient's stomach wall (12), and an operation device (16, 18) for operating the stretching device when implanted to stretch the stomach wall portion such that satiety is created.

A method for modifying the eating behavior of a patient equipped with a gastric restriction apparatus includes the steps of: a. providing an adjustable gastric band (AGB); b. providing a pressure sensor to measure pressure within the AGB; c. providing a processing unit containing instructions to collect a set of pressure measurement and to analyze the set pressure measurement; d. providing a data base comprising data concerning pressure exerted within the AGB by a bolus of liquid food, a bolus of semiliquid food, and a bolus of solid food; e. recording the sets of pressure measurements; f. recording the results; g. communicating the results; h. placing the AGB in position; i. measuring the pressure within the AGB; j. using the distinction of the current eating pattern to modify the eating behavior of the patient.
