(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.結(jié)論：BENDIT微導(dǎo)管超好的彎曲和扭轉(zhuǎn)能力，以及在彎曲位置的穩(wěn)定性，能夠快速導(dǎo)航并優(yōu)化支架（彈簧圈等）的部署。研究者強烈建議進行臨床研究，以確定這些導(dǎo)航優(yōu)勢是否能更有效地治療顱內(nèi)和外周動脈瘤。專家評價：
“我們之前使用Bendit微導(dǎo)管的經(jīng)驗，保證我們有效使用Bendit微導(dǎo)管的彎曲和扭轉(zhuǎn)導(dǎo)航以及定位能力，以及彎曲位置的穩(wěn)定性，Bendit微導(dǎo)管有可能治療常規(guī)微導(dǎo)管不適用的動脈瘤，例如側(cè)壁動脈瘤，需要定向控制和尖端定位，同時提供囊內(nèi)裝置。”
