Patent

CA 2463870

Surgical tissue fasteners and related deployment systems and methods are disclosed. A tissue fastener used to join multiple tissue layers includes a first member, a second member, and a connecting member connecting the first and second members. In some embodiments, the first and second members are configured to expand from a delivered state to a deployed state in which the fastener secures the tissue layers together. Other tissue fastener embodiments include means for applying a substantially constant force on the tissue layers and/or means for adjusting a length of the connecting member between the first and second members.

L'invention concerne des agrafes tissulaires chirurgicales ainsi que des systèmes et procédés de déploiement associés. Selon cette invention, une agrafe tissulaire utilisée pour rassembler plusieurs couches de tissu comprend un premier élément, un deuxième élément et un élément de liaison reliant ces premier et deuxième éléments. Dans certains modes de réalisation, ces premier et deuxième éléments sont conçus pour s'étendre d'un état appliqué à un état déployé dans lequel ladite agrafe fixe les couches de tissu les unes aux autres. Dans d'autres modes de réalisation desdites agrafes tissulaires, ces dernières comportent des moyens permettant d'appliquer une force sensiblement constante sur les couches de tissu et/ou des moyens permettant d'ajuster une longueur de l'élément de liaison entre lesdits premier et deuxième éléments.
