Title (EN) BALLOON CATHETER PROVIDED WITH FLEXIBLE CONNECTING PART BETWEEN TIP AND BALLOON
(FR) CATHÉTER À BALLONNET ÉQUIPÉ D'UNE PARTIE DE RACCORDEMENT FLEXIBLE ENTRE LA POINTE ET LE BALLONNET
(ZH) 一种头端与球囊之间设有柔性连接部的球囊导管
Abstract:
(EN) A balloon catheter provided with a flexible connecting part (4) between a tip (11) and a balloon (3), comprising an inner tube (1), an outer tube (2), the balloon (3), and the tip (11). The inner tube (1) is provided within the outer tube (2). A guidewire runs through the inner tube (1). The balloon (3) is sleeved at the distal extremity of the inner tube (1). Also, one extremity of the balloon (3) is connected to the outer tube (2); the other extremity is connected to the inner tube (1). The flexible connecting part (4) is provided at the rear side of the tip (11). The distal extremity of the inner tube (1) protrudes the balloon (3) then connects the flexible connecting part (4). When introduced into a blood vessel, the flexible connecting part (4) bends to the shape of the blood vessel. When performing a post-expansion operation on a stent, the balloon catheter is not affected by stent mesh or a stent beam, thus favoring smooth progression of a post-expansion process, and reducing the occurrence of risks.
(FR) L'invention concerne un cathéter à ballonnet équipé d'une partie de raccordement flexible (4) entre une pointe (11) et un ballonnet (3), comprenant un tube interne (1), un tube externe (2), le ballonnet (3) et la pointe (11). Le tube interne (1) est disposé à l'intérieur du tube externe (2). Un fil-guide se prolonge à travers le tube interne (1). Le ballonnet (3) est enfilé sur l'extrémité distale du tube interne (1). En outre, une extrémité du ballonnet (3) est raccordée au tube externe (2) ; l'autre extrémité est raccordée au tube interne (1). La partie de raccordement flexible (4) est disposée à l'arrière de la pointe (11). Le ballonnet (3) fait saillie depuis l'extrémité distale du tube interne (1) qui se raccorde ensuite à la partie de raccordement flexible (4). Lorsqu'elle est introduite dans un vaisseau sanguin, la partie de raccordement flexible (4) s'incurve pour épouser la forme du vaisseau sanguin. Lors de la mise en œuvre d'une intervention post-expansion sur un stent, le cathéter à ballonnet n'est pas affecté par les mailles du stent ou une entretoise du stent, ce qui favorise le bon déroulement d'un processus post-expansion et réduit l'apparition de risques.
(ZH) 一种头端(11)与球囊(3)之间设有柔性连接部(4)的球囊导管,包括内管(1)、外管(2)、球囊(3)和头端(11),内管(1)设置于外管(2)中,导丝由内管(1)中穿过,球囊(3)套设于内管(1)的远端,且所述球囊(3)的一端与所述外管(2)相连,另一端与所述内管(1)相连,所述头端(11)后侧设有柔性连接部(4),所述内管(1)的远端伸出球囊(3)后与所述柔性连接部(4)相连,所述柔性连接部(4)进入血管后顺应血管形状弯曲。在对支架进行后扩张操作时,所述球囊导管不会受到支架网眼或支架梁的影响,便于后扩张过程顺利进行,降低风险的发生。
