A suture anchor has a deformable portion for engaging with a wall of a borehole in a first tissue member, a shaft for providing a force to the deformable portion to deform the deformable portion to cause the deformable portion to engage the wall of the borehole, a suture retaining portion in at least one of the deformable portion and the shaft for retaining two suture portions in the retaining portion with a loop formed between the two suture portions, the loop adapted to traverse a second tissue member to be attached to the first tissue member; and wherein application of the force to deform the deformable portion causes engagement of the deformable portion with the borehole to secure the suture anchor to the first tissue and clamping of at least one of the two suture portions in the suture retaining portion thereby to secure the suture forming the loop in the suture retaining portion and secure the second tissue to the suture anchor.

L'invention concerne un dispositif d'ancrage de suture comprenant une partie déformable destinée à venir en contact avec la paroi d'un orifice dans un premier élément tissulaire, un arbre générant une force destinée à déformer la partie déformable de manière que la partie déformable vienne en contact avec la paroi de l'orifice, une partie de retenue de suture au moins dans la partie déformable ou dans l'arbre servant à retenir deux parties de suture dans la partie de retenue, une boucle étant formée entre les deux parties de suture, et adaptée pour traverser un second élément tissulaire destiné à être rattaché au premier élément tissulaire. L'application de la force destinée à déformer la partie déformable permet à la partie déformable de venir en contact avec l'orifice de manière à fixer le dispositif d'ancrage de suture au premier tissu et à bloquer au moins l'une des deux parties de suture dans la partie de retenue de suture afin de serrer la suture formant la boucle dans la partie de retenue de suture et de serrer le second tissu au dispositif d'ancrage de suture.
