    • Apparatus and methods are described for performing protected angioplasty and stenting of a patient's carotid bifurcation. An integrated catheter system can be configured in a rapid- exchange version or in an over-the-wire version. The catheter system includes a self- expanding stent, a stent delivery sheath, a combination angioplasty balloon catheter and stent pusher catheter, an embolic protection device and, in the rapid-exchange version, an auto-releasing sheath. The method includes: inserting a guiding catheter to the carotid bifurcation; inserting the catheter system through the guiding catheter; advancing the embolic protection device beyond the lesion; positioning the stent and balloon segment of the catheter system at the lesion; releasing the self-expanding stent; pulling the stent delivery sheath back into the guiding catheter; positioning and deploying the protection member; advancing the combination angioplasty balloon catheter and stent pusher catheter and inflating the angioplasty balloon within the lesion; deflating the angioplasty balloon and withdrawing the combination angioplasty balloon catheter and stent pusher catheter and stent delivery sheath together; and aspirating potential emboli through the guiding catheter.
    • 描述了用于执行患者颈动脉分叉的保护性血管成形术和支架置入的装置和方法。 集成的导管系统可以以快速交换版本或线上版本配置。 导管系统包括自扩张支架,支架输送护套,组合血管成形术球囊导管和支架推进器导管,栓塞保护装置,并且在快速更换版本中具有自动释放护套。 该方法包括:将引导导管插入颈动脉分叉; 通过引导导管插入导管系统; 推进栓塞保护装置超过病变; 将导管系统的支架和气囊段定位在病变处; 释放自扩张支架; 将支架输送护套拉回导引导管; 定位和部署保护构件; 推进组合血管成形术球囊导管和支架推动导管,并使病变内的血管成形术气囊膨胀; 将血管成形术气囊放气并将组合血管成形术球囊导管和支架推进导管和支架输送护套并入; 并通过引导导管抽吸潜在的栓塞。
