Title (EN) MEDICAL DEVICE AND PREPARATION METHOD THEREFOR
(FR) DISPOSITIF MÉDICAL ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 医疗器械及其制备方法
Abstract:
(EN) A medical device and a preparation method therefor, which may effectively mold a protrusion (11, 21, 31) on a balloon structure (10, 20, 30) without affecting the usage performance of the balloon structure (10, 20, 30), and improve the anti-offload capabilities of a support (100) so as to prevent the support (100) from disengaging from the balloon structure (10, 20, 30) during a pushing process, thus reducing the damage to a blood vessel wall during the pushing process, and preventing an end portion of the support (100) from forking as well as preventing a bell mouth effect caused by forking. The preparation method for a medical device comprises: providing an initial structure (101) of a balloon structure (10, 20, 30) in a folded state; pressing a support (100) onto the initial structure (101); mounting a pretreatment mold (410, 510, 610, 710) on the initial structure (101) on which the support (100) is pressed such that the initial structure (101) on which the bracket (100) is pressed is accommodated in a molding cavity (511, 716) of the the pretreatment mold (410, 510, 610, 710); enabling the initial structure (101) to be heated in the molding cavity (511, 716) and be infused with a fluid so that the initial structure (101) forms a protrusion in the molding cavity (511, 716) and is shaped to obtain a molding structure of the balloon structure (10, 20, 30).
(FR) Un dispositif médical et son procédé de préparation, qui peuvent mouler efficacement une saillie (11, 21, 31) sur une structure de ballonnet (10, 20, 30) sans affecter la performance d'utilisation de la structure de ballonnet (10, 20, 30), et améliorer les capacités anti-déchargement d'un support (100) de façon à empêcher le support (100) de se dégager de la structure de ballonnet (10, 20, 30) pendant un processus de poussée, réduisant ainsi les dommages causés à une paroi de vaisseau sanguin pendant le processus de poussée, et empêchant une partie d'extrémité du support (100) de se casser ainsi que d'empêcher un effet de bouche de cloche provoqué par un oubli. Le procédé de préparation d'un dispositif médical consiste à : fournir une structure initiale (101) d'une structure de ballonnet (10, 20, 30) dans un état plié; presser un support (100) sur la structure initiale (101); monter un moule de prétraitement (410, 510, 610, 710) sur la structure initiale (101) sur laquelle le support (100) est pressé de telle sorte que la structure initiale (101) sur laquelle le support (100) est pressé dans une cavité de moulage (511, 716) du moule de prétraitement (410, 510, 610, 710); permettre à la structure initiale (101) d'être chauffée dans la cavité de moulage (511, 716) et être infusée avec un fluide de telle sorte que la structure initiale (101) forme une saillie dans la cavité de moulage (511, 716) et est façonnée pour obtenir une structure de moulage de la structure de ballonnet (10, 20, 30).
(ZH) 一种医疗器械及其制备方法,可有效成型球囊结构(10、20、30)上的凸起(11、21、31),同时还不会影响球囊结构(10、20、30)的使用性能,并提升支架(100)的抗脱载能力,防止支架(100)在推送过程中从球囊结构(10、20、30)上脱落,减小推送过程血管壁损伤,防止支架(100)端部分叉及因分叉导致的喇叭口效应。医疗器械的制备方法包括:提供折叠状态的球囊结构(10、20、30)的初始结构(101);将支架(100)压握于初始结构(101)上;将预处理模具(410、510、610、710)加装于压握有支架(100)的初始结构(101)上,使压握有支架(100)的初始结构(101)容置于预处理模具(410、510、610、710)的成型腔(511、716)中;使初始结构(101)在成型腔(511、716)中受热并接收流体的灌注,使初始结构(101)在成型腔(511、716)中形成一凸起并定型,以取得球囊结构(10、20、30)的成型结构。
