(A) The Bendit 17 can be navigated through a braided LVIS stent to reach the aneurysm, without a guidewire. (B) The Bendit 17 can be maneuvered through a braided LVIS Jr stent to enter the left carotid artery without a guidewire. (C, D) The Bendit 17 was twice able to access a nearly occluded right carotid artery and gain access to the lumen without a guidewire. The Headway 21, a comparator device with a guidewire, could not be used to cross the area of stenosis. (E) The Bendit 17 used to deploy the LVIS 4.5 stent along the right carotid artery in a steady manner.结论:BENDIT微导管超好的弯曲和扭转能力,以及在弯曲位置的稳定性,能够快速导航并优化支架(弹簧圈等)的部署。研究者强烈建议进行临床研究,以确定这些导航优势是否能更有效地治疗颅内和外周动脉瘤。专家评价:
“我们之前使用Bendit微导管的经验,保证我们有效使用Bendit微导管的弯曲和扭转导航以及定位能力,以及弯曲位置的稳定性,Bendit微导管有可能治疗常规微导管不适用的动脉瘤,例如侧壁动脉瘤,需要定向控制和尖端定位,同时提供囊内装置。”
