Title (EN) BALLOON CATHETER WITH DRUG COATING
(FR) CATHÉTER À BALLONNET AVEC REVÊTEMENT DE MEDICAMENT
(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 first balloon (100) with a drug coating, and a sheath (220). The pushing catheter (310) has a proximal end and a distal end, which are opposite each other. Each first balloon (100) with a drug coating is fixedly arranged at the distal end of the pushing catheter (310). The sheath (220) can move with respect to the pushing catheter (310), so that each first balloon (100) with a drug coating is housed in the sheath (220) or is exposed outside the sheath (220). By means of being additionally provided with the sheath (220), the balloon catheter (1000) with a drug coating prevents a blood flow from eroding a drug coating during a delivery process, thus effectively reducing the drug loss rate during the delivery process and improving the effectiveness of the balloon catheter with a drug coating.
(FR) L'invention concerne un cathéter à ballonnet (1000) avec un revêtement de médicament. Le cathéter à ballonnet comprend un cathéter de poussée (310), au moins un premier ballonnet (100) avec un revêtement de médicament, et une gaine (220). Le cathéter de poussée (310) a une extrémité proximale et une extrémité distale qui sont opposées l'une à l'autre. Chaque premier ballonnet (100) avec un revêtement de médicament est disposé de manière fixe au niveau de l'extrémité distale du cathéter de poussée (310). La gaine (220) peut se déplacer par rapport au cathéter de poussée (310), de telle sorte que chaque premier ballonnet (100) avec un revêtement de médicament est logé dans la gaine (220) ou est exposé à l'extérieur de la gaine (220). En étant en outre pourvu de la gaine (220), le cathéter à ballonnet (1000) avec un revêtement de médicament empêche un écoulement sanguin d'éroder un revêtement de médicament pendant un processus de distribution, ce qui permet de réduire efficacement le taux de perte de médicament pendant le processus de distribution et d'améliorer l'efficacité du cathéter à ballonnet avec un revêtement de médicament.
(ZH) 一种药物涂层球囊导管(1000),包括推送导管(310)、至少一第一药物涂层球囊(100)及护套(220)。推送导管(310)具有相对的近端和远端,各所述第一药物涂层球囊(100)固定地设置在所述推送导管(310)的远端,所述护套(220)相对所述推送导管(310)可活动,以使各所述第一药物涂层球囊(100)收容在所述护套(220)内或裸露在所述护套(220)外。该药物涂层球囊导管(1000)通过增设护套(220),从而避免输送过程中血流对药物涂层的冲刷,进而有效降低输送过程中的药物损失率,提高药物涂层球囊导管的有效性。
