An adjustable suture assembly is provided that may be employed in various surgical procedures to draw and/or hold tissue and/or muscle together. The suture assembly may include a suture lock or tensioner that is adjustably securable to two or more lengths of suture to provide a surgeon with an ability to maintain tissue or muscle in one secured position and subsequently readjust the suture assembly to maintain the tissue or muscle in a different secured position. The suture assembly may include two or more sutures having an anchor attached to an end of each suture for anchoring the suture to desired tissue or muscle. An endoscopic suturing device is provided to deliver and place two or more sutures in tissue or muscle during a surgical procedure. The suturing device may be configured to carry a plurlaity of sutures so that multiple sutures can be placed in tissue or muscle during a single intubation of the device. The suture assembly and suturing device may be employed with an endoscope to facilitate surgical treatment of obesity which involves narrowing and/or disabling the pyloric sphincter to reduce the rate of gastric emptying.

L'invention concerne un ensemble de suture réglable qui peut s'utiliser dans diverses opérations chirurgicales pour tirer les uns vers les autres et/ou retenir ensemble des tissus et/ou des muscles. L'ensemble de suture peut comprendre un verrou ou un tensionneur qui peut être fixé de manière réglable sur deux ou plusieurs longueurs de suture afin de donner au chirurgien la possibilité de maintenir le tissu ou le muscle dans une position fie et de réajuster ensuite l'ensemble de suture pour maintenir le tissu ou le muscle dans une position de fixation différente. L'ensemble de suture peut comprendre deux ou plusieurs sutures possédant une ancre attachée à une extrémité de chaque suture de manière à ancrer la suture au muscle ou au tissu désiré. Un dispositif de suture endoscopique est conçu pour effectuer plusieurs sutures, de manière à ce que plusieurs sutures puissent être placées dans le muscle ou le tissu pendant une seule intubation du dispositif. L'ensemble de suture et le dispositif de suture peuvent s'utiliser avec un endoscope pour faciliter le traitement de l'obésité, qui consiste à rétrécir et/ou à désactiver le sphincter pylorique afin de réduire la vitesse de vidange gastrique.
