Abstract: front page image
(EN)A method for manufacturing a dilating catheter of a drug balloon, and a coiled balloon having flaps. The preparation method comprises the following steps: folding a balloon (S210) to form n flaps , and coiling each flap to form an arc structure, and making an acute angle ranging from 30°to 75°, formed by a tangent line connected by midpoints of arcs where two adjacent flaps are located, so as to obtain the coiled balloon having flaps, n being an integer greater than or equal to 2; coating a drug solution on the external surface of the coiled balloon having flaps, and performing drying to obtain the coiled balloon having flaps and coated with a drug (S220); wrapping, by using a flexible material, the coiled balloon having flaps and coated with drugs, then coiling each flap, removing the flexible material and performing sterilization, so as to obtain the dilating catheter of a drug-coated balloon (S230). The dilating catheter of a drug-coated balloon, obtained by using the manufacturing method, has relatively high drug delivery efficiency.
(FR)La présente invention concerne un procédé de production d'un cathéter de dilatation d'un ballonnet de médicament et un ballonnet enroulé comportant des volets. Le procédé de préparation comprend les étapes suivantes consistant à : plier un ballonnet (S210) pour former n volets et enrouler chaque volet pour former une structure en arc et former un angle aigu compris entre 30° et 75°, formé par une ligne tangente reliée par des points médians des arcs où deux volets adjacents sont situés, de manière à obtenir le ballonnet enroulé comportant des volets, n étant un nombre entier supérieur ou égal à 2 ; revêtir d'une solution de médicament la surface externe du ballonnet enroulé comportant les volets et sécher pour obtenir le ballonnet enroulé comportant des volets et revêtu d'un médicament (S220) ; envelopper, à l'aide d'un matériau souple, le ballonnet enroulé comportant des volets et revêtu de médicaments, puis enrouler chaque volet, retirer le matériau souple et stériliser, pour obtenir le cathéter de dilatation d'un ballonnet revêtu de médicament (S230). Le cathéter de dilatation d'un ballonnet revêtu de médicament, obtenu selon le procédé de production, présente une efficacité d'administration de médicament relativement élevée.
(ZH)一种药物球囊扩张导管的制备方法及折翼卷绕球囊。该制备方法包括如下步骤:将球囊进行折叠(S210),形成n个折翼,卷绕每个折翼至该折翼形成弧形结构,且使相邻两个折翼所在的弧线的中点的切线形成的锐角为30°~75°,得到该折翼卷绕球囊,其中,n为大于或者等于2的整数;在折翼卷绕球囊的外表面上涂敷药物溶液,干燥,得到粘附有药物的折翼卷绕球囊(S220);使用柔性材料包裹附有药物的折翼卷绕球囊,再对每个折翼进行卷绕,去除柔性材料,灭菌,得到药物球囊扩充导管(S230)。该药物球囊扩张导管的制备方法制备得到的药物球囊扩张导管具有较高的药物输送效率。
