Patent

CA 2464063

Endoscopic devices and methods used for fastening multiple tissue layers, such as, for example, an endoscopic fundoplication procedure, are disclosed. The device may include, for example, an elongated tubular member having a proximal end for extending outside of the body and a distal end for positioning proximate the multiple tissue layers, a grasper configured for positioning proximate the distal end of the tubular member and for grasping at least one of the multiple tissue layers, a device coupled to the distal end of the tubular member for folding the multiple tissue layers together, a tissue fastener configured to be inserted into the tissue layers to hold the tissue layers together, and a fastener head for inserting the tissue fastener into the tissue layers.

L'invention concerne des dispositifs endoscopiques et des méthodes utiles pour fixer plusieurs couches de tissu, notamment au moyen d'une opération de fundoplication endoscopique, par exemple. Ce dispositif peut comprendre, par exemple, un élément tubulaire allongé comportant une extrémité proximale pouvant se prolonger à l'extérieur du corps et une extrémité distale pouvant être placée au voisinage des couches de tissu, un élément de préhension pouvant être placé au voisinage des couches de tissu et permettant de saisir l'une au moins de ces couches de tissu, un dispositif couplé à l'extrémité distale de l'élément tubulaire et permettant de plier les couches de tissu ensemble, un dispositif de fixation de tissu conçu pour être inséré dans les couches de tissu de manière à retenir les couches de tissu ensemble, ainsi qu'une tête de fixation destinée à insérer le dispositif de fixation de tissu dans les couches de tissu.
