Aptus Endosystems, a medical device company that develops advanced technology for endovascular aneurysm repair, has successfully treated the first series of patients in the US with its HeliFX aortic securement system.

The HeliFX system is based on helical anchor technology, and allows independent endograft fixation to the aorta, and will mimic the hand suturing performed during open surgical repair of abdominal aortic aneurysms.

In endovascular aneurysm repair, a minimally invasive catheter-based system is used to implant a metal and fabric endograft to separate blood flow from the aneurysm to prevent potential rupture and death.

The HeliFX system provides physicians with a new technology to repair endovascular grafts in both de novo (initial) endovascular aneurysm repair procedures as well as in secondary interventions, with improved fixation and sealing of the endograft.

Arizona Heart Institute Peripheral Vascular Surgery and Endovascular Research director Venkatesh Ramaiah said that the EndoAnchor deployment is found to be easy in high-surgical risk patients with challenging anatomy who require improved fixation and sealing for long term durability.

”We were able to treat an angulated and conical proximal neck, and also correct an intra-operative Type 1 endoleak – all in a patient who had limited treatment alternatives," Ramaiah added.

The first application of the device at the Heart & Vascular Institute of El Camino Hospital in Mountain View, California was to treat a patient with a short, angulated infrarenal neck, who otherwise was bound for open surgical repair.

"The HeliFX System is a game-changing technology that will allow us to safely and effectively offer stent graft therapy to a much broader population of patients," said James Joye, the institute’s director of research, education and interventional services.

Aptus Endosystems CEO Jeff Elkins said that the independent and physician-controlled proximal fixation treatment, using EndoAnchors represents a step toward addressing and preventing long-term complications and making endovascular aneurysm repair the definitive solution for treating aortic aneurysms.
