CA 2397285

A heartburn and reflux disease treatment apparatus comprises an adjustable restriction device (234) implanted in a patient engaging the stomach close to the cardia, or alternatively engaging the esophagus (206), to form a restricted food passageway in the stomach or esophagus. An adjustment device is implanted in the patient for adjusting the restriction device to restrict and enlarge the passageway, and a hydraulic operation means (236) is implanted in the patient for operating the adjustment device. By using a wireless remote control (238) the patient can control the hydraulic operation means, whereby the restriction device works like an artificial sphincter.

L'invention concerne un appareil servant à traiter le pyrosis et la maladie du reflux. Cet appareil comporte un dispositif de restriction réglable (234) implanté dans le corps d'un patient et agissant sur l'estomac proche du cardia ou agissant alternativement sur l'oesophage (206) afin de restreindre le passage de la nourriture dans l'estomac ou l'oesophage. Un dispositif de réglage est implanté dans le corps du patient afin de régler le dispositif de restriction et ainsi rétrécir ou élargir le passage, et des moyens de manoeuvre hydrauliques (236) sont implantés dans le corps du patient afin de commander ce dispositif de réglage. Grâce à une télécommande (238) sans fil, le patient peut contrôler les moyens de manoeuvre hydrauliques, le dispositif de restriction fonctionnant ainsi comme un sphincter artificiel.
