A tissue anchoring system, including a tissue anchoring device (1), and tissue anchors (20). The tissue anchoring device (1) includes a housing (2), and a tissue anchor (12) positioned on the tissue anchoring device (1) that will be inserted into a tissue or secured onto a tissue. The device (1) may optionally have a plunger assembly (5) slidably positioned in the housing to assist advancing anchor into a tissue. The tissue anchor (20) has a barb end (21), and a shaft (120). The barb end (21) is adapted to resist removal from a tissue after the anchor has been inserted. The tissue anchor shaft (120), and the barb end (21) may be hollow. The anchor shaft (120) has an attachment member (23) distal from the barb end (21) for direct attachment (23) to a tissue or for attachment of sutures or slings. The tissue anchors (20) may include an adjustment mechanism for intra or post-operative adjustments.

La présente invention concerne un système de fixation des tissus comprenant un dispositif de fixation des tissus (1) et des broches de fixation des tissus (20). Le dispositif de fixation des tissus (1) comprend un logement (2) et une broche de fixation des tissus (12) placée sur le dispositif de fixation des tissus (1) destiné à être inséré dans un tissu ou attaché sur un tissu. Le dispositif de l'invention (1) peut facultativement comporter un ensemble piston (5) placé coulissant dans le logement, qui facilite la progression de la broche de fixation dans le tissu. La broche de fixation (20) comprend une extrémité à barbule (21) et une tige (120). L'extrémité à barbule (21) permet d'empêcher que la broche de fixation ne s'échappe du tissu une fois insérée. La tige (120) et l'extrémité à barbule (21) de la broche de fixation peuvent être creuses. La tige (120) comprend un élément de fixation (23) distal par rapport à l'extrémité à barbule (21), qui peut être directement attaché sur un tissu ou qui peut être utilisé pour attacher des sutures ou des sangles. Les dispositifs de fixation des tissus (20) peuvent comprendre un mécanisme de réglage permettant les réglages peropératoires ou postopératoires.
