AAA occurs when a portion of the aorta bulges into an aneurysm because of a weakening of the vessel wall, which may result in life threatening internal bleeding upon rupture. The most commonly used treatment is a stent graft implanted through a minimally invasive procedure. The problem is that hostile anatomies create complications and these grafts either leak or migrate. ZeroNeck is mimicking the suturing technique performed in open surgery, which was found to be the best leakage and migration solution. By reproducing the integrity of a hand-sewn seal, ZeroNeck brings a proven solution from the world of open surgery to endovascular procedures.
Although AAA is one of the most serious cardiovascular diseases, many AAAs are never detected. Most AAA patients do not have symptoms at the time of their initial diagnosis. AAAs generally are discovered coincidentally during procedures to treat or diagnose unrelated medical conditions.
The overall patient mortality rate for ruptured AAA is approximately 80%, making it among the leading causes of death in the United States. Once diagnosed, patients with AAA require either non-invasive monitoring, or, depending on the size and rate of growth of the AAA, endovascular aneurysm repair (EVAR) or open surgical repair.
