Clinical Investigation Design A prospective, open-label, non-randomized, interventional clinical study, sponsored by Endospan Ltd. Patients will be followed-up for five years.
Investigational Device The Horizon™ Abdominal Aortic Aneurysm Stent Graft System and its designated Delivery System.
Purpose The purpose of the study is to evaluate the safety and performance of the Horizon™ AAA Stent Graft System for the treatment of infrarenal abdominal aortic and/or aortoiliac aneurysms. The results of this study will be used as supportive data for CE Marking submission in the European Union (EU).
Objectives The primary objectives of the study are to evaluate the safety and performance of the Horizon™ AAA Stent graft System.
Primary End Points Safety endpoints include proportion of patients free from device related Major Adverse Events (MAEs) within 1 month of the endovascular procedure. Performance endpoints include successful delivery and deployment of the device; and absence of the following at 1 month follow-up: aneurysm growth ≥5mm, type I or III endoleaks, stent graft occlusion, conversion to open surgery, rupture and stent graft migration.
Subject population Thirty (30) patients having infrarenal abdominal aortic and/or aortoiliac aneurysms, having Iliac/femoral access vessel morphology that is compatible with vascular access techniques and devices.
Treatment All patients will be treated by implantation of the Horizon™ Abdominal Aortic Aneurysm Stent graft System.

Male or female participants at least 18 years old.
- Male and female age ≥ 18.
- Presence of at least one of the following:
- Abdominal aortic aneurysm ≥ 5.0cm in diameter (perpendicular to the line of flow). ii. Abdominal aortic aneurysm 4.5-5.5cm in diameter which increased in size - ≥ 0.5cm over 6 months or 1.0cm over one year. iii. Abdominal aortic aneurysm >50% larger than the normal aortic diameter.
- Patient is considered an appropriate candidate for an elective surgery, as evaluated by Physical Status Classification System I, II or III (American Society of Anesthesiologists).
- Femoral artery diameter of ≥6mm, documented by CTA or MRA that allows endovascular access to the aneurismal site with a 14 Fr delivery catheter.
- Access vessels morphology suitable for endovascular repair in terms of tortuosity, calcification and angulation, documented by CTA or MRA.
- To be eligible to receive the Horizon having the following characteristics, as demonstrated on CTA or MRA imaging: I. Infrarenal aortic diameter of 18-28 mm II. Aortic length (lower renal artery to lowest point of aortic bifurcation) of 115-150 mm III. Iliac artery diameter of 10-19 mm IV. Proximal aortic neck length ≥ 15 mm V. Proximal aortic neck angulation ≤ 60° VI. Diameter measured 20mm above aortic bifurcation floor should be ≥ 20mm VII. Aortic bifurcation angulation of ≥ 70°. 7. Patient understands and is voluntarily willing to participate as evidenced by personally signing the Informed Consent document.
- If female and of childbearing potential , patients who are:
- pregnant (as determined by a positive pregnancy test performed between 10 to 5 days before implantation date), or
- intend to become pregnant during the study period, or
- do not accept to use adequate double barrier contraception methods for the entire study duration to avoid pregnancy
- Life expectancy of less than 1 year.
- Any medical condition that, according to the investigator's decision, might expose the patient to increased risk by the investigational device or procedure.
- Patient is in need for an emergent surgery for a ruptured aneurysm.
- Patient with an increased risk for aneurysm rupture, such as, saccular aneurysm, aneurysm with isolated wall protrusion and penetrating ulcers of the aorta.
- A dissecting, acutely ruptured, or leaking aneurysm, or an acute vascular injury due to trauma.
- Presence of thrombus or atheroma in proximal aortic neck covering >50% of the endoluminal surface.
- Presence of diffuse atherosclerotic disease in either common iliac artery that reduces the iliac artery diameter to <6mm.
- Congenital vascular disease in which the placement of the stent graft will cause occlusion of major arterial flow.
- Aneurysm with any of the following characteristics: suprarenal, isolated ilio-femoral, mycotic, inflammatory or para-anastomotic pseudoaneurysm.
- Patient has an untreated thoracic aneurysm > 5.5 cm in diameter.

- Patient has a reversed conical neck defined as a > 4mm distal increase over a 10 mm length.
- Patient has ectatic iliac arteries requiring bilateral exclusion of hypogastric blood flow.
- Patient whose arterial access site is not anticipated to accommodate the 14 Fr diameter of the Horizon™ Delivery System, due to size, tortuosity or hostile groins (scarring, obesity, or previous failed puncture).

|Official title||A Prospective Open-label Non-randomized Pivotal Study to Evaluate the Safety and Performance of the Horizon™ Abdominal Aortic Aneurysm (AAA) Stent Graft System|
|Description||Possible benefits: It is believed that the Horizon™ AAA Stent Graft System implantation may offer a number of benefits over conventional and recently developed treatment options for patients suffering from AAA. These other treatment modalities include open surgery and the more recently evolved EVAR. The Horizon™ AAA Stent graft System has a low profile of 14Fr and is implanted through a percutaneous approach. The modular bottom-up construction requires a single-sided femoral access and there is no need for cannulation of the contralateral limb, a requirement present in the majority of commercially available devices. These features are anticipated to result in a simplified procedure with less surgical trauma, shorter procedure time, lower levels of radiation exposure and shorter hospitalization periods. Moreover, the device is flexible enough to reach also tortuous anatomies and its fixation elements reduce the concern of migration and type I endoleaks. As such, it is believed that the Horizon™ AAA Stent graft System may have potential clinical advantages and may exhibit benefits over commercially available stent-grafts. Hypothesis: In this clinical study safety and performance primary endpoints are compared between HORIZON™ and those reported for the Lifeline Registry of Endovascular Aneurysm Repair (Control).|
