Technical Field
The invention relates to the field of vascular treatment, in particular to a vascular expandable device.
Background
An aneurysm is an abnormal bulge or ballooning of a blood vessel caused by the vessel wall becoming weakened due to disease, injury, or congenital abnormality. Aneurysms have thin, weak walls and have a tendency to rupture, which can lead to stroke, death, disability, and the like. A method of treating an aneurysm includes inserting a flow diversion stent or braid into a parent vessel including the aneurysm to be treated. Such stents or braids may be inserted into a blood vessel in a collapsed state, positioned next to the neck of an aneurysm, and expanded into apposition with the vessel wall. If the stent or braid has a sufficiently low porosity, the stent or braid may function to prevent blood flow through the device and into the aneurysm to induce isolation of the aneurysm.
Among most present vasodilatation devices, all be integral type expanding mechanism, unable stage type expansion to at the complicated position of some vascular circumstances, the vascular wall is thick too big, often can take place gasbag central point holding power undersize, causes the condition of interrupting the expansion or unable effective support.
