摘要： Apparatus and methods are provided for treating lesions within a blood vessel include a two-layer angioplasty balloon designed for the simultaneous deployment of multiple balloon-expanded stents. The high-compliance (elastic) outer balloon secures stent position. The low-compliance (inelastic) inner balloon drives angioplasty and stent expansion. Stent deployment starts with the injection of a small quantity of fluid into the outer balloon, which bulges slightly at both ends and into the spaces between the stents and, once the stent has expanded a little, between the struts of the stents. The injection port to the outer balloon is then closed, and fluid is injected only into the inner balloon, which expands, opening the stents.

摘要： Flexible high-pressure angioplasty balloons are disclosed herein which utilize an inflatable balloon positioned upon the catheter and a supporting structure secured over or along the catheter at a first location proximal to the balloon and at a second location distal to the balloon. Inflation of the balloon reconfigures the supporting structure to urge the first location and the second location towards one another thereby inhibiting longitudinal elongation of the balloon relative to the catheter. The supporting structure may surround, support, or otherwise extend over the entire length of the balloon and allows for the balloon to retain increased flexibility which enables the balloon to bend or curve even at relatively high inflation pressures.
摘要翻译：本文公开了柔性高压血管成形术球囊，其利用位于导管上的可充气球囊，以及在靠近球囊的第一位置处和靠近球囊的第二位置处固定在导管上或沿着导管固定的支撑结构。气囊的充气重新配置支撑结构以将第一位置和第二位置朝向彼此推动，从而抑制气囊相对于导管的纵向伸长。支撑结构可围绕，支撑或以其它方式在球囊的整个长度上延伸，并允许球囊保持增加的柔性，这使得球囊即使在相对高的充气压力下也可弯曲或弯曲。
