The invention in certain aspects relates to a surgical fastener for fastening tissue segments having tissue surfaces. The fastener includes a first fastener member having a base and a piercing element connected to the base for piercing the tissue segments to be fastened, a second fastener member having an opening for receiving and retaining the piercing element of the first fastener member such that the tissue segments to be fastened are retained between the first and second fastening members, and means for promoting adhesion between the tissue surfaces. The invention also relates to related methods and devices for promoting adhesion of tissue segments and preventing fastener migration, especially in an endoscopic procedure for the treatment of GERD. Certains aspects de l'invention concernent un dispositif de fixation chirurgical qui sert à fixer des segments tissulaires présentant des surfaces tissulaires. Le dispositif de fixation comprend un premier élément de fixation présentant un base et un élément de perforation connecté à la base afin de perforer des segments tissulaires à fixer, un second élément de fixation présentant une ouverture qui sert à recevoir et à maintenir l'élément de perforation du premier élément de fixation de sorte que les segments tissulaires à fixer sont maintenus entre le premier et le second élément de fixation, et un système destiné à favoriser l'adhérence entre les surfaces tissulaires. L'invention a également pour objet des procédés et des dispositifs pour favoriser l'adhérence entre des segments tissulaires et éviter la migration du dispositif de fixation, notamment dans le cadre d'une procédure endoscopique de traitement d'une pathologie due au reflux gastro-oesophagien.
