A flexible cutting filament or wire (16) is led through the carpal tunnel, beneath the transverse carpal tunnel, by a passer (10). Thereafter, the opposite ends of the wire are secured in an instrument (30) which tightens the wire and may be used to move the wire as a cutting tool to transect the overlying ligament, while preserving surrounding tissues. The small wire diameter enables minimally invasive techniques to limit post-operative pain and speed recovery.

L'invention concerne un filament ou un fil de coupe flexible conçu pour être acheminé par le canal carpien, sous le ligament annulaire antérieur du carpe, par un guide. Les extrémités opposées du fil sont ensuite fixées à un instrument permettant de serrer le fil, pouvant être utilisé pour déplacer le fil et pour l'utiliser comme un outil de coupe pour sectionner transversalement le ligament sus-jacent sans abîmer les tissus adjacents. Le faible diamètre du fil permet d'avoir recours à des techniques de chirurgie à effraction minimale réduisant les douleurs et le temps de récupération postopératoires.
