Abbott血管設備公司(Abbot Park, IL, USA)研發了一種血管外閉合系統，配備了鎳鈦諾夾子能夠在診斷或者介入血管手術之后，安全地閉合股動脈穿刺點。這套系統已經獲得了許多國家的批準，而且也得到了美國食品藥品管理局的批準。

根據Abbbot公司說法，只需要使用該設備中的4個夾子就能夠進行安全的血管外閉合。這種夾子完全從血管外部閉合穿刺部位。
 
Clip Closes Arteries From Outside
 
An extravascular closure system developed by Abbott Vascular Devices (Abbot Park, IL, USA) features a nitinol clip designed to achieve a secure closure of the femoral artery access site following diagnostic or interventional vascular procedures. The system has been approved by the U.S. Food and Drug Administration (FDA), following previous approval in many other countries. 

According to Abbbot, only four clicks of the device are required to achieve a secure extravascular closure. The clip closes the closure site entirely from the outside of the vessel.
