EVAR WITH ENDOANCHOR FIXATION FOR SHORT AAA NECKS (<10 MM AND ≥4 MM) Endurant II Stent Graft Systems
The Endurant™ II/IIs AAA Stent Graft System used in combination with the Heli-FX™ EndoAnchor™ System is the first AAA short neck solution independent of renal stenting. Where approved for this use, Endurant II/IIs is indicated for patients with aortic neck lengths <10mm and ≥4mm and <60° infrarenal angle.
Medtronic offers the first EVAR with EndoAnchor fixation for patients with AAA necks <10mm and ≥4mm.
ANCHOR Registry short neck one year clinical results support the use of Endurant II/IIs system and Heli-FX EndoAnchor system in short aortic necks.*

Data on file. As of June 2017
Re-interventions are defined as any endovascular or surgical procedure performed following the completion of the operative initial implantation procedure (thus on subsequent occasion after final closure of the last artery access site) which involves the targeted vascular segment treated by the Endurant™ stent graft system, including access sites and bypasses of the targeted vascular segment in which there is either manipulation of the implanted Endurant™ stent graft, or implantation or usage of additional devices.
Technical success defined as: successful delivery and deployment of the endograft and each EndoAnchor™ implant without unintentional coverage of the renal arteries.
Two investigator-reported cases of unsuccessful procedures: 1) failure to deliver the main body endograft to intended landing zone, 2) persistent Type Ia endoleak
There were 4 cases where the investigator assessed that one EndoAnchor™ implant did not penetrated the aortic wall and 1 case of unsuccessful implantation of EndoAnchor™ implants.
At least 1 EndoAnchor™ implant didn’t adequately penetrate aortic wall (N=4, All 4 procedures determined to be successful by the investigator). Unsuccessful delivery of main body to intended landing zone (N=3, Endografts delivered slightly distal to intended target; 1 cuff covered renal). One subject with combination of low endograft landing, unintentional coverage of a renal artery with cuff, and unsuccessful implant of EndoAnchor™ implants).
AAA diameter increase is defined as > 5 mm increase in maximum diameter measured at 1 year as compared to 1 month post-implantation measurement. AAA diameter decrease is defined as a > 5 mm decrease in maximum diameter at 1 year as compared to a 1 month post-implantation measurement.
Neck length measured as: Proximal neck length. Proximal neck length is defined as the non-aneurysmal aortic neck length measured from the lowest main renal artery to where the dilatation of the aneurysm begins (i.e., less than 10% increase from the diameter at the lowest renal artery).
