(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(qiáng)烈建議進(jìn)行臨床研究,以確定這些導(dǎo)航優(yōu)勢(shì)是否能更有效地治療顱內(nèi)和外周動(dòng)脈瘤。專家評(píng)價(jià):
“我們之前使用Bendit微導(dǎo)管的經(jīng)驗(yàn),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(dòng)脈瘤,例如側(cè)壁動(dòng)脈瘤,需要定向控制和尖端定位,同時(shí)提供囊內(nèi)裝置?!?
