A method and apparatus for tipping surgical sutures which includes winding the suture around a drum while continuously monitoring the suture diameter in x and y directions and adjusting the tension on the suture to control the suture diameter as it is being wound. The drum is then placed in an apparatus which passes selected portions of the suture through a mist of cyanoacrylate tipping agent generated by ultrasonic atomization. The tipping agent quickly cures and the tipped portion of the suture may be cut to create a tipped end for insertion into a surgical needle to form a needle suture device.

Méthode et appareil pour poser un embout sur les sutures chirurgicales comprenant l'enroulement de la suture autour d'un tambour tout en surveillant continuellement le diamètre de la suture dans les axes x et y et en réglant la tension de la suture pour en contrôler le diamètre pendant qu'elle est enroulée. Le tambour est ensuite placé dans un appareil qui fait passer certaines parties de la suture dans un nuage d'agent de cyanoacrylate servant à créer un embout et produit par pulvérisation à ultrasons. L'agent durcit rapidement et l'embout de la suture peut être coupé pour créer une extrémité qui pourra s'insérer dans une aiguille chirurgicale de façon à former un dispositif de suture à aiguille.
