Abstract
(EN)
A tissue anchor (20, 70, 120, 220, 270, 320, 420, 520A, 520B, 620) is provided that includes a metal wire (22, 122, 222, 322, 422, 622) shaped so as to define a straight anchor-shaft portion (26, 276) and a tissue-coupling portion (31, 131, 231, 331, 431, 631) extending therefrom. The tissue anchor is configured such that when the tissue-coupling portion is in an unconstrained state: (a) the tissue-coupling portion crosses itself at first (40A, 340A, 640A) and second (40B, 340B, 640B) loop-end longitudinal portions along the wire, so as to define a looped portion (44, 344, 644), which generally defines a looped-portion plane (46, 346), (b) the first loop-end longitudinal portion (40A, 340 A, 640 A) is closer to a first proximal wire end (24A) along the wire than the second loop-end longitudinal portion (40B, 340B, 640B) is to the first proximal wire end (24A) along the wire, and (c) a greatest absolute distance (Dl) between the first loop-end longitudinal portion (40 A, 340 A, 640A) and the first proximal wire end (24A) is greater than a greatest absolute distance (D2) between the second loop-end longitudinal portion (40B, 340B, 640B) and the first proximal wire end (24A). Other embodiments are also described.

L'invention concerne un ancrage de tissu (20,70, 120, 220, 270, 320 420, 520A, 520B, 620) comprenant un fil métallique (22, 122, 222, 322, 422, 622) formé de manière à définir une partie d'axe d'ancrage droit (26, 276) et une partie de couplage de tissu (31, 131, 231, 331, 431, 631) s'étendant à partir de celle-ci. L'ancrage de tissu est configuré de sorte que, lorsque la partie de couplage de tissu se trouve dans un état non contraint: (a) la partie de couplage de tissu s'entrecroise au niveau des première (40A, 340A, 640A) et seconde (40B, 340B, 640B) parties longitudinales d'extrémité de boucle le long du fil métallique, de manière à définir une partie bouclée (44, 344, 644), qui définit généralement un plan de partie bouclée (46, 346), (b) la première partie longitudinale d'extrémité de boucle (40A, 340A, 640A) est plus proche d'une première extrémité de fil proximale (24A) le long du fil que la seconde partie longitudinale d'extrémité de boucle (40B, 340B, 640B) est à la première extrémité de fil proximale (24A) le long du fil, et (c) une plus grande distance absolue (Dl) entre la première partie longitudinale d'extrémité de boucle (40A, 340A, 640A) et la première extrémité de fil proximale (24A) est supérieure à une distance absolue maximale (D2) entre la seconde partie longitudinale d'extrémité de boucle (40B, 340B, 640B) et la première extrémité de fil proximale (24A). L'invention concerne également d'autres modes de réalisation.
