Abstract
The invention relates to an intraluminar method of treating a reflux disease in a patient by implanting a device comprising an movement restriction device that, when implanted in a patient, fills a volume in the patient's abdomen that is close to and at least partially above the patient's cardia when the patient is in a standing position. The invention further relates to a method of restoring the location of the cardia in a patient suffering from a reflux disease and to an instrument suitable to use with intraluminar method and/or restoration method. Also disclosed are instruments treating a patient suffering hiatal hernia and providing a movement restriction device to be invaginated in the stomach fundus wall.
Claims8
A gastroscopic instrument for providing a movement restriction device to be invaginated in the stomach fundus wall of a human patient to treat reflux disease, the instrument comprising:
- (i) an elongated member having a proximal end and a distal end, the elongated member having a diameter less than that of the patient's esophagus and being flexible, thereby allowing introduction of the flexible elongated member with its distal end first through the patient's throat, esophagus and into the stomach to the fundus wall;
- (ii) an operable stomach penetration device provided on the elongated member at the distal end thereof for penetrating the stomach fundus wall to create a hole in the stomach fundus wall, to allow introduction of the elongated member through the hole;
- (iii) an expandable member provided on the elongated member proximal to the penetration device, when penetrating said stomach wall, to hold the elongated member in a position in which the elongated member extends through the stomach fundus wall and is prevented from moving through the hole in the proximal direction, wherein the expandable member is expandable at least radially substantially perpendicular to the elongated member to abut against the fundus wall on the outside thereof;
- (iv) a forming device provided on the elongated member proximal to the expandable member to abut against the fundus wall on the inside thereof, the forming device together with the expandable member being adapted to form the stomach fundus wall, wherein the forming device and the expandable member are shaped and sized such that the expandable member can retract relative to the forming device to a position in which the expandable member is at least partially enclosed within the forming device to thereby pull the stomach wall against the forming device to form said stomach fundus wall, and
- (v) an insertion device for inserting the movement restriction device through the hole in the stomach fundus wall to the outside thereof to be invaginated in the fundus wall.
