By using a guidewire fixator, the distal guidewire position can be secured in an artery. This new principle enables a method for fenestrated endovascular aortic repair where the connection between the aortic branches and the stent graft fenestrations is made before inserting and deploying the stent graft.
This is conducted using a fenestrated stent graft with preloaded catheters, through which the prepositioned and distally secured guidewires from the branches are inserted.
This report covers the method when implementing a single fenestration stent graft in pig.
Successful tests with single and dual fenestrated grafts have been conducted in pigs.
通过使用导丝固定器,可将远端导丝位置固定在动脉中。这一新原理为开窗式血管内主动脉修复术提供了一种方法,即在插入和展开支架移植物之前,先在主动脉分支与支架移植物开窗之间建立连接。
使用带有预装导管的开窗式支架移植物进行操作,通过这些导管插入来自分支的预先定位并在远端固定的导丝。
本报告涵盖了在猪身上实施单开窗支架移植物的方法。
已在猪身上成功进行了单开窗和双开窗移植物的测试。
