An implantable constriction device for forming a restricted stoma opening in the stomach or esophagus of a patient comprises an elongate composite structure adapted to constrict the stomach or esophagus of the patient. The elongate composite structure is composed of a base material, such as hard silicone, making the composite structure self-supporting. Property improving means is provided for improving at last one physical property of the composite structure other than self-supporting properties, such as fatigue resistance, liquid impermeability, aggressive body cells resistance, anti-friction properties and lifetime.
L'invention concerne un dispositif de constriction implantable destiné à former un orifice de stomie restreint dans l'estomac ou l'oesophage d'un patient, et comprenant une structure composite allongée conçue pour resserrer l'estomac ou l'oesophage du patient. La structure composite allongée est constituée d'une matière de base, telle que du silicone dur, la rendant autoportante. L'invention concerne également des moyens d'amélioration de propriété physique destinés à améliorer au moins une propriété physique de la structure composite autre que l'autoportance, et notamment la résistance à la fatigue, l'imperméabilité aux liquides, la résistance aux cellules somatiques agressives, les propriétés antifriction et la durée de vie.
