## Abstract

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be movement restriction device of a controlled size. The 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.

## Claims

### Claim 1

An apparatus for treating reflux disease in a human or animal mammal patient, the apparatus comprising:
a first movement restriction device segment; and
a second movement restriction device segment;
wherein:
the first and second movement restriction device segments are configured to form an implantable movement restriction device having a shape and size allowing it to be at least partly invaginated by the patient's stomach fundus wall, and to be arranged to restrict movement of the cardiac notch of the patient's stomach towards the patient's diaphragm without causing an obstruction of a food passage way of the patient;
said movement restriction device is adapted to disassemble upon leaving its invaginated position in the patient's stomach fundus wall;
the first movement restriction device segment having an inner face configured to engage with an inner face of the second movement restriction device segment, and the first movement restriction device segment and the second movement restriction device segment being shaped such that the implantable movement restriction device, formed when the segments are assembled, has an outer surface having an elliptical point; and
each one of said first and second movement restriction device segments has a shape and size allowing it to separately pass through the food passage way, thereby reducing the risk of causing obstruction or ileus in the patient's intestine.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the first and second movement restriction device segments are adapted to pass through a trocar, for assembly and implantation of the movement restriction device into the abdominal cavity.

### Claim 3 (depends on 2)

The apparatus according to claim 2, wherein the first and second movement restriction device segments comprise a flexible outer shape allowing them to pass through the trocar.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein the first and second movement restriction device segments are solid.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein a largest circumference of the assembled movement restriction device is 50 millimeters or more.
