Although major technological advances have occurred in coronary artery angioplasty balloons and steerable wire systems, there have been surprisingly few advances in the development and designs for balloons in the peripheral circulation. For example, a #7 French shaft has become the standard for most peripheral as well as visceral angioplasty balloons. In most instances, the shaft is unnecessarily large and not only interferes with tractability over the conventional wire but in certain situations is also unnecessarily traumatic to the vascular intima as the catheter is passed to the angioplasty site. For these reasons a newly designed catheter with a shaft measuring 1.67 mm (#5 French) has been designed to incorporate a variety of dimensional balloons varying from 2 mm through 7 mm. In addition, the open end allows passage of a .035 inch wire and consequently the balloon is ideally suited for applications from vessels as small as the tibial circulation or renal visceral or iliac circulation.
尽管冠状动脉血管成形术球囊和可操纵导丝系统已经取得了重大技术进步,但外周循环球囊的开发和设计却出人意料地进展甚微。例如,7法国规格的导管鞘已成为大多数外周及内脏血管成形术球囊的标准配置。在大多数情况下,导管鞘过大,不仅会影响在传统导丝上的操控性,而且在某些情况下,当导管插入血管成形术部位时,对血管内膜造成不必要的创伤。基于这些原因,一种新设计的导管鞘直径为1.67毫米(5法国规格),可配备各种尺寸从2毫米到7毫米不等的球囊。此外,开口端允许0.035英寸的导丝通过,因此该球囊非常适合用于诸如胫部循环、肾内脏或髂循环等小血管的应用。
