The present invention relates to a medical device that is for medical procedures relating to gastric reductions. The device has an elongate body having a 5 flexible portion and a stiffened portion extending from the flexible portion, the stiffened portion can be gripped by a grasper for manoeuvring the device about a gastric conduit of a patient, and a locking mechanism that is operable to secure the flexible portion in a looped configuration.

The present invention relates to an automatic tension measurer, comprising: a band lengthily formed in a longitudinal direction; a main body formed to allow the band to be guided thereinto such that one-side end portion of the band is fixed and the other-side end portion thereof is drawn to the outside; a marking part implemented in the main body, and formed so as to enable marking in the band at a specific position in response to the tension applied to the band; and a stopper formed in the main body, and stopping the band at a specific position.

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.

An obesity treatment device is provided, the device comprising: 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.

The present invention relates to a reflux disease treatment apparatus, comprising two or more movement restriction device segments adapted to form an implantable movement restriction device with an elongated shape that maintains cardia in the correct position. The movement restriction device has proximal and a distal end, wherein the distal end is adapted to stabilize and hold the proximal end. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The distal end can be further adapted to treat obesity, for example by stretching the wall of the stomach or filling out a volume of the stomach.

An intraluminar method of treating a reflux disease in a patient by implanting a device comprising a non-encircling implantable movement restriction device that, when implanted in a patient, restricts the movement of the cardiac notch in relation to the diaphragm muscle, preventing the cardia from sliding through the esophageal hiatus. The intraluminar method comprises introducing an instrument through the esophagus and into the stomach of the patient, introducing the non-encircling implantable movement restriction device through the esophagus using said instrument, affixing the non-encircling movement restriction device to the fundus wall, such that it does not encircle the esophagus or stomach, thereby preventing the cardia from sliding through the esophageal hiatus and thus reducing reflux disease without encircling the esophagus or stomach.

A sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.

A gastroscopic method and instrument for treating obesity of a patient, using a device adapted to stretch a part of the stomach wall of said patient. The method comprises the steps of: inserting the device into the stomach through the esophagus, placing the device in contact with the stomach wall, and fixating the device to the stomach wall such that the device can stretch a part of the stomach wall.

The present invention relates to a reflux disease treatment apparatus, apparatus, comprising an implantable movement restriction device that maintains cardia in the correct position and an implantable stimulation device adapted to engage with the cardia sphincter of a patient. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The invention can be combined with various methods for treating obesity, in particular methods that creates satiety by stretching the wall of the stomach or fills out a volume of the stomach.

A method is used to reduce a volume of a stomach of a patient. The method includes inverting a portion of a stomach wall to thereby create an inverted portion. An expandable member is positioned adjacent to the outer surface of the inverted portion. The expandable member is expanded to thereby expand the inverted portion. The expanded expandable member has a first outer diameter. A base region of the inverted portion is cinched to thereby capture the expanded expandable member in the expanded inverted portion. The expanded expandable member has a first outer diameter. Expanding and cinching provide a cinch diameter to first outer diameter ratio from approximately 0.5:1 to approximately 0.9:1.
