Title (EN) BALLOON CATHETER WITH DRUG COATING
(FR) CATHÉTER À BALLONNET À REVÊTEMENT MÉDICAMENTEUX
(ZH) 药物涂层球囊导管
Abstract:
(EN) Disclosed is a balloon catheter (1000) with a drug coating. The balloon catheter comprises a pushing catheter (310), at least one expandable first balloon (100) located at a distal end of the pushing catheter (310), and a pre-expansion mechanism. The first balloon (100) is fixedly arranged on the pushing catheter (310). The pre-expansion mechanism (200) comprises an expansion sleeve (220) and a connector (240). The expansion sleeve (220) is used for housing the first balloon (100) before the first balloon (100) is not expanded and when same is pre-expanded. The connector (240) is connected to the expansion sleeve (220) and axially moves with respect to the pushing catheter (310) after the first balloon (100) is pre-expanded, so that the first balloon (100) is exposed outside the expansion sleeve (220). The balloon catheter (1000) with a drug coating can effectively pre-expand a lesion location and can also effectively prevent the loss of a balloon with a drug coating during a delivery process, and is simple in terms of a surgical operation process.
(FR) L'invention concerne un cathéter à ballonnet (1000) à un revêtement médicamenteux. Le cathéter à ballonnet comprend un cathéter de poussée (310), au moins un premier ballonnet (100) expansible situé à une extrémité distale du cathéter de poussée (310), et un mécanisme de pré-expansion. Le premier ballonnet (100) est disposé de manière fixe sur le cathéter de poussée (310). Le mécanisme de pré-expansion (200) comprend un manchon d'expansion (220) et un connecteur (240). Le manchon d'expansion (220) est utilisé pour loger le premier ballonnet (100) avant que le premier ballonnet (100) ne soit pas déployé et lorsqu'il est pré-expansé. Le connecteur (240) est connecté au manchon d'expansion (220) et se déplace axialement par rapport au cathéter de poussée (310) après que le premier ballonnet (100) est pré-expansé, de telle sorte que le premier ballonnet (100) est exposé à l'extérieur du manchon d'expansion (220). Le cathéter à ballonnet (1000) à un revêtement médicamenteux peut pré-élargir efficacement un emplacement de lésion et peut également empêcher efficacement la perte d'un ballonnet à un revêtement médicamenteux pendant un processus d’administration, et est simple en termes de processus d'opération chirurgicale.
(ZH) 一种药物涂层球囊导管(1000),包括推送导管(310)、位于推送导管(310)远端的至少一个可扩张的第一球囊(100)及预扩张机构。第一球囊(100)固定地设置在推送导管(310)上。预扩张机构(200)包括扩张套(220)及连接件(240)。扩张套(220)用于在第一球囊(100)未扩张前及预扩张时收容第一球囊(100)。连接件(240)连接扩张套(220),且在第一球囊(100)预扩张后相对推送导管(310)沿轴向运动,以使第一球囊(100)裸露在扩张套(220)外。该药物涂层球囊导管(1000)既可对病变部位进行有效地预扩张,同时可有效避免药物涂层球囊在输送过程中的损失,且手术操作过程简单。
