The present invention is directed to gastrointestinal or enteric (including biliary) anastomosis and the like. The anastomotic device of the invention is a three dimensional woven tube of wire. The outer loops or ends of the tube fold or loop back on deployme nt in a manner which holds the luminal interface of the anastomotic site into apposition at the deployment site. The woven tube is deployed using a protective sleeve and nose assembly. Adjustment of the wire diameter and/or material properties of the wire can cause the anastomotic device to remain in place permanently or, for example, in the case of the intestine to slough through the two apposing walls of the lumen resulting in the device safely passing through the intestine leaving a naturally healed, properly f unctioning anastomosis.
L'invention concerne l'anastomose gastrointestinale ou entérique (y compris biliaire) et similaire. Ledit dispositif anastomotique de l'invention est un tube tissé tridimensionnel en fil. Les boucles ou extrémités extérieures du tube se replient vers l'arrière lors du déploiement, de manière que l'interface luminale du site anastomotique soit maintenue apposée sur le site de déploiement. Le tube tissé est déployé à l'aide d'un ensemble gaine protectrice et nez. Le réglage du diamètre du fil et/ou des propriétés matérielles du fil peut permettre la mise en place permanente du dispositif anastomotique ou, par exemple, dans le cas de l'intestin, son détachement dans les deux parois juxtaposées de la lumière, ce qui lui permet de traverser l'intestin en toute sécurité et de laisser une anastomose cicatrisant naturellement et fonctionnant correctement.
