一種新系統(tǒng)被設(shè)計(jì)用于輸送心內(nèi)支架移植物，微創(chuàng)治療腹部主動(dòng)脈瘤(AAA)。

Visiflex輸送系統(tǒng)是由Endologix(Irvine, CA, USA)公司研制開發(fā)的，設(shè)計(jì)用于提高ELG輸送導(dǎo)管的柔軟性。該系統(tǒng)在外鞘出配備了不透輻射的帶狀標(biāo)記物以及模塊組成成分，能夠增加導(dǎo)管可視性，方便了在困難解剖部位平穩(wěn)地抽出導(dǎo)管。Visiflex輸送系統(tǒng)已經(jīng)獲得了歐洲CE標(biāo)志，并得到了美國食品藥品管理局的批準(zhǔn)。

這種新型輸送系統(tǒng)被設(shè)計(jì)用于Powerlink ELG系統(tǒng)，該系統(tǒng)也是由Endologix研制開發(fā)的，具有雙頭設(shè)計(jì)便于使用，避免了分支脫落的危險(xiǎn)。一片鈷鉻合金盒能夠降低在曲折部位曲折纏繞。這種設(shè)備只需要在腿部切開一個(gè)小口，通過皮下進(jìn)入另外一條腿進(jìn)行輸送。
 
Improved Delivery of Aortic Stent Grafts
 
A new system is designed for the delivery of an endoluminal stent graft (ELG) for the minimally invasive treatment of abdominal aortic aneurysm (AAA).

The Visiflex delivery system, developed by Endologix (Irvine, CA, USA), is designed to provide improved catheter flexibility in ELG delivery. The system has an integrated radiopaque band marker on the outer sheath and molded component parts that are expected to enhance catheter visibility and facilitate smoother withdrawal in difficult anatomies. The Visiflex delivery system has received the European CE Mark and has also been approved by the U.S. Food and Drug Administration (FDA).

The new delivery system is designed to be used with the Powerlink ELG system, also developed by Endologix, which features a one-piece bifurcated design to facilitate its use and eliminate the risk of limb detachment. A one-piece cobalt-chromium alloy cage reduces the risk of kinking in tortuous anatomy. The device requires only a small incision in one leg and percutaneous access in the other leg for delivery.
