Device profile of EndoAnchors for aortic stent graft implantation: overview of their safety and efficacy

IntroductionEndovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) are established techniques to treat abdominal aortic aneurysms (AAA) and thoracic aortic aneurysms (TAA). However, there are limitations when challenging proximal neck anatomy is present. Heli-FX EndoAnchors have been used in addition to EVAR and TEVAR to improve proximal sealing of a stent-graft, but there are limited data available on their outcomes, safety, and efficacy.Areas CoveredThe properties and development of Heli-FX EndoAnchors are evaluated. The evidence of various clinical outcomes, safety, and efficacy is interrogated with the augmented use of Heli-FX EndoAnchors with EVAR or TEVAR.Expert OpinionChallenging proximal neck anatomy can be problematic during EVAR or TEVAR. EndoAnchors may be part of the solution - used either prophylactically or therapeutically. The safety and efficacy databases are building but long-term data are still not available for this device and there remains inadequate data to support its routine use. Judicious patient selection is still needed.
