Benefits of technology

[0009]It is an object of the present invention to overcome, or at least reduce, some of the problems associated with existing surgical treatments of Gastroesophageal Reflux Disease (GERD).

Problems solved by technology

However, this device has a number of complications, including migrating through and damaging the oesophagus.
A problem with providing an implantable device associated with the oesophagus is that the outer surface of the oesophagus is only comprised of oesophagus muscle tissue, which is very easy to damage or migrate through.
This is probably one reason why the Anglechik prosthesis described above has resulted in many complications, such as migration.

Embodiment Construction

[0118]FIG. 1A is a schematic view depicting an apparatus 11, including a movement restriction device 10 of a biocompatible material, for treating reflux disease, in accordance with the invention, implanted in a human patient. In FIG. 1A, the device 10 is invaginated in the fundus. The device 10 comprises a body 13 having an outer surface 15 suitable for resting against a portion of the outside wall 16a of the stomach fundus wall 16 in a position between the patient's diaphragm 18 and at least a portion of the lower part of the invaginated stomach fundus wall 16. Thus, with the device 10 invaginated in this fashion, movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, thereby the cardia is prevented from sliding through the patient's diaphragm opening into the patient's thorax 20 and the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen is maintained

[0119]The body 13 is inflatable and ...

Abstract

An implantable device for the treatment of acid reflux disease has a body including an outer surface adapted to rest against a patient's fundus wall. The device, when implanted in a patient, fills a volume in the patient's abdomen in the cardia area and above the cardia of the patient, when standing. The body prevents the cardia from moving through the diaphragm opening into the thorax, thereby preventing reflux by keeping the abdominal pressure supporting the cardia sphincter muscle. The device may be affixed to stomach tissue. The device may also be invaginated or otherwise indirectly secured in position.

Description

TECHNICAL FIELD[0001]The present invention relates to an apparatus for treating Gastroesophageal Reflux Disease (GERD).BACKGROUND[0002]Gastroesophageal Reflux Disease (GERD), or acid reflux disease, is a chronic condition resulting in mucosal damage in the oesophagus produced by the recurring occurrence of acid reflux in the oesophagus. This is commonly due to transient or permanent changes in the barrier between the oesophagus and the stomach. This can be due to incompetence of the lower esophageal sphincter (LES), transient LES relaxation, impaired expulsion of gastric reflux from the esophagus, or a hiatal hernia.[0003]Gastroesophageal Reflux Disease can be treated in a number of different ways. Treatments include, but are not limited to, both medical and surgical treatments. A standard surgical treatment, which sometimes is preferred over longtime use of medication, is Nissen fundoplication surgery, in which the upper curve of the stomach (the fundus) is wrapped around the LES t...
