CA 2191582

A suture locking button is described. The device includes a base element with a first axial passage for receiving at least one, and preferably two. suture filaments that is attached via a frangible membrane to a locking element. The locking element is adapted for movement from a first position, where the looking element extends outwardly from the base element, to a second position, where the locking element is disposed within the base element by disrupting the frangible membrane to trap the suture filament(s) within the first axial passage between the locking element and the base element. The locking element may have a flange integral with its proximal end that effectively prevents the base element from backing out of the tissue in a direction proximal to the tissue. The invention also pertains to the combination of a suture and a device for securing the suture to a tissue. A method for securing tissue by way of a suture is also included within the scope of the invention.

On décrit un rivet de blocage d'une suture comprenant une base dotée d'un premier passage axial destiné à recevoir un et/ou de préférence deux fils attachés via une membrane cassante à un élément de blocage conçu pour être déplacé d'une première position, dans laquelle il s'étend vers l'extérieur à partir de la base, dans une seconde position dans laquelle il se place dans la base par rupture de la membrane cassante afin de piéger le(s) fil(s) de suture dans le premier passage axial situé entre l'élément de blocage et la base. L'élément de blocage peut être pourvu d'un rebord monobloc par construction avec son extrémité proximale, lequel empêche efficacement la base de ressortir du tissu vers la surface du corps. L'invention est également caractérisée par la combinaison d'une suture et d'un dispositif destiné à fixer la suture sur un tissu. On décrit encore un procédé de fixation d'un tissu au moyen d'une suture.
