Zusammenfassung: | The invention in certain aspects relates to a surgical fastener for fastenin g tissue segments having tissue surfaces. The fastener includes a first fasten er member having a base and a piercing element connected to the base for pierci ng the tissue segments to be fastened, a second fastener member having an openi ng for receiving and retaining the piercing element of the first fastener membe r 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 f or promoting adhesion of tissue segments and preventing fastener migration, especially in an endoscopic procedure for the treatment of gastroesophagen reflex disease (gerd). |
