Installation and removal unrestricted self expandability aneurysm cover instrument

摘要

Being the self expandability aneurysm cover instrument which does the form of the cylindrical skeletal frame which energization is done in outside direction, the proximal end of the cylindrical skeletal frame, forming tilt angle of skew vis-a-vis the axis of the cylindrical skeletal frame, the self expandability aneurysm cover instrument which forms the loop which extends. The positioning tub, has extended from the proximal end of the skeletal frame, when this positioning tub is pulled, as for the cylindrical skeletal frame collapsing, from the blood vessel the pulling tsu the cover instrument it becomes a reduction diameter state where it can include.
