Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed. Using the teaching of the present disclosure, a surgeon can customize a fastener to the particular surgery or even to the particular portion of surgery being performed during the surgery.
L'invention concerne des fixations (10) de fils présentant des extensions (16, 18) dont la longueur peut être 100 fois la largeur de la fixation (10) servant à fixer les articles tels que des valves de prothèses sur un patient pendant la chirurgie avec effraction minimale. Les fixations (10) sont manipulées, tendues et formées à partir d'une extrémité des extensions de manière à immobiliser, tendre, couper et fléchir les extensions des fixations. L'invention concerne un procédé permettant de poser les fixations.
