The ANCHOR registry is a multi-center, post-market, non-interventional, non-randomized, prospective study.
Subjects must sign an ICF prior to obtaining any study specific information. Subjects are eligible to be consented up to 30 days post-procedure.
Enrolled subjects will be followed as per local 'standard of care' for up to 5 years post procedure. Study recommended follow-up is per SVS and ESVS guidance.

- Protocol B has composite primary safety endpoints, tabulated separately for the abdominal, thoracic and advanced disease arms [ Time Frame: Through 12 months ]
The primary safety endpoint is defined by:
i. freedom from device-related serious adverse events at 12 months and ii. freedom from procedure-related serious adverse events at 12 months iii. freedom from aneurysm-related mortality defined as: i. death within 30 days of the index procedure ii. death within 30 days of a secondary procedure to address the aneurysm iii. death from rupture of the treated aneurysm
- Protocol B has composite primary effectiveness endpoints, tabulated separately for the abdominal, thoracic and advanced disease arms [ Time Frame: Through 12 months ]
The primary effectiveness endpoint requires all of the following:
i successful implantation of the minimum number of EndoAnchor™ and ii freedom from migration at 12 months and iii freedom from Type I endoleak at the targeted attachment site(s) at 12 months
- Protocol C has composite primary safety endpoint [ Time Frame: Through 12 months ]
The primary safety endpoint is defined by:
- device-related serious adverse events at 12 months
- aneurysm-related mortality defined as:
i. death within 30 days of the index procedure ii. death within 30 days of a secondary procedure to address the aneurysm iii. death from rupture of the treated aneurysm
- Protocol C have composite primary effectiveness endpoint [ Time Frame: Through 12 months ]
The primary effectiveness endpoint is treatment success which is defined as the successful implantation of EndoAnchor™ implants at the index procedure, and the absence of:
- migration at 12 months and
- Type I endoleak at the targeted attachment site(s) at 12 months
- Protocol B has the secondary endpoints chosen to reflect the clinical success and safety of Heli-FX™. Each of the secondary endpoints will be measured individually at 30 days and 12 months and yearly thereafter. [ Time Frame: Through 5 years ]
- Technical success defined as successful deployment of EndoAnchor™ at their intended location. Technical success will be assessed separately for the target attachment sites; proximally and/or distally
- Clinical success will be defined as the successful implantation of the suggested number of EndoAnchor™ at the index procedure, and the absence of: death as a result of aneurysm-related treatment; Type Ia endoleak; Type Ib endoleak (TAA and advanced disease only); endograft infection; endograft migration; loss of endograft fabric integrity as a result of the EndoAnchor™; Rupture of the treated aneurysm; Conversion to open surgical repair
- Secondary aneurysm-related interventions after EndoAnchor™ implantation
- all-cause mortality
- Freedom from EndoAnchor™ fracture
- Protocol C has the secondary endpoints chosen to reflect the clinical success and safety of Heli-FX™. Each of the secondary endpoints will be measured individually at 30 days and 12 months and yearly thereafter. [ Time Frame: Through 5 years ]
- Technical success defined as successful deployment of EndoAnchor™ at their intended location. Technical success will be assessed separately for the target attachment sites; proximally and/or distally
- Clinical success will be defined as the successful implantation of EndoAnchor™ at the index procedure, and the absence of: aneurysm-related mortality; Type Ia endoleak; endograft infection; endograft migration; loss of endograft fabric integrity as a result of the EndoAnchor™; Rupture of the treated aneurysm; Conversion to open surgical repair
