Endograft stapling solution

We strive to provide AAA patients undergoing Endovascular Aneurysm Repair with a long-lasting sealing and fixation solution for their endograft

Zeroneck was developed to mimic the reliable hand-sewn suturing technique from open surgery, evenly
distributing staples around the circumference of the aorta, creating leak and migration free anastomosis.

AAA

AAA – Abdominal Aortic Aneurysm – occurs when a portion of the aorta bulges into an aneurysm. This usually happens because of a weakened vessel wall, and can cause life threatening internal bleeding if ruptured. The standard treatment is a stent graft implanted through a minimally invasive procedure called EVAR – Endovascular Aneurysm Repair. In the USA alone, there are currently 2 million aortic aneurysm cases with an additional 200,000 cases discovered every year. The overall patient mortality rate for a ruptured AAA is approximately 80%, making it among the leading causes of death.

THE NEED

A successful EVAR procedure depends on the anatomy of the aorta, which often varies significantly from patient to patient.
Short aortic necks, or angulated aortas, result in poor apposition of the stent graft to the aortic wall.
This in turn, leads to graft migration and leakage – which increases intra-saccular pressure and risks rupture of the aneurysm.

Unfortunately, 30% to 40% of AAA patients present with such complex aortic necks.

THE SOLUTION

ZeroNeck™ is a long-lasting FIXATION and SEALING device that holds the stent graft securely in place.
It uses a smart stapling mechanism that enables multiple staples to simultaneously penetrate the stent graft and the aortic wall. The end result is a suturing effect similar to one performed manually during open surgery that permanently isolates the aneurysm. With a small profile delivery system, ZeroNeck is quickly deployed via a single release action.
Our technology enables the implementation of endograft procedures in almost all types of anatomies and can dramatically reduce complications and reinterventions.

Zeroneck implant’s opening and
positioning inside the stent graft
provides a stable structure for the
staples.

Staples are released from
the delivery sheath to be set
perpendicular to the stent
graft, ready to be activated.

To activate the staples the
balloon applies pressure on
the base of each one, pushing
them through the stent graft
and the aortic wall,
all the way to the adventitia.

The eagle-like wings of the staples
are pre-shaped to open up and
“hug” the graft and aortic wall from
both sides, securing sealing and
fixation of the stent graft
