Abstract
(EN)
A method of creating a feature on a needle. The method comprising the steps of providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter; gripping a distal portion of the needle about the outer diameter; gripping a proximal portion of the needle about an outer diameter; and applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.
(FR)
L'invention concerne une méthode de création d'une caractéristique sur une aiguille. La méthode comprend les étapes consistant à fournir une aiguille ayant une extrémité distale pointue destinée à être insérée dans un site d'insertion chez un sujet, une extrémité proximale, et une paroi tubulaire définissant un diamètre interne et un diamètre externe ; saisir une partie distale de l'aiguille autour du diamètre externe ; saisir une partie proximale de l'aiguille autour d'un diamètre externe ; et appliquer une force de compression entre la partie distale et la partie proximale suffisante pour effectuer une déformation vers l'extérieur de la paroi tubulaire, ce qui permet d'augmenter le diamètre extérieur de la paroi tubulaire entre la partie distale et la partie proximale.
