Title
(EN) SYSTEMS, DEVICES AND METHODS OF MAKING SURGICAL SUTURES HAVING REFORMED, REDUCED DIAMETER TIPS
(FR) SYSTÈMES, DISPOSITIFS ET PROCÉDÉS DE FABRICATION DE FILS DE SUTURE CHIRURGICAUX POSSÉDANT DES POINTES REFORMÉES À DIAMÈTRE RÉDUIT
Abstract
(EN)
A method of making a surgical suture having a reformed tip includes providing an elongated fiber having a first end, a second end, a central axis extending between the first and second ends thereof, and an outer surface that defines a cross-sectional dimension of the elongated fiber, and compressing a center region of the elongated fiber that is located between the first and second ends thereof for reshaping the center region into a core mass and a deformed mass that extends laterally outside the cross-sectional dimension of said elongated fiber. The method includes separating the deformed mass of the center region from the core mass of the center region so that only the core mass remains for interconnecting the first and second ends of the elongated fiber, and after separating the deformed mass from the core mass, reshaping the core mass into a reformed mass having a reformed mass central axis that is offset from the central axis of the elongated fiber.
(FR)
Un procédé de fabrication de fil de suture chirurgical possédant une pointe reformée, comprend la fourniture d'une fibre allongée comprenant une première extrémité, une seconde extrémité, un axe central s'étendant entre les première et seconde extrémités de celle-ci, et une surface extérieure qui définit une dimension transversale de la fibre allongée, et la compression d'une région centrale de la fibre allongée qui est située entre les première et seconde extrémités de celle-ci pour remodeler la région centrale en une masse noyau et une masse déformée qui s'étend latéralement à l'extérieur de la dimension transversale de ladite fibre allongée. Le procédé consiste à séparer la masse déformée de la région centrale de la masse noyau de la région centrale de sorte que seule la masse noyau subsiste pour relier entre elles les première et seconde extrémités de la fibre allongée, et après la séparation de la masse déformée de la masse noyau, le remodelage de la masse noyau en une masse reformée possédant un axe central de masse reformée qui est décalé par rapport à l'axe central de la fibre allongée.
