The Vascutek Custom Fenestrated Anaconda Post-Market Surveillance Study

AnacondaTM Custom Fenestrated Devices (CFD) are designed for the endovascular repair of abdominal aortic aneurysms (AAA) for cases where the aneurysm extends superiorly very close to or involving the renal arteries, leaving insufficient neck length for infrarenal device sealing. The non-CE marked devices are custom designed based on CT scan data of the patient's aorta and regulated in accordance with the Medical Device Directive (93/42/EEC) and associated country specific regulations as applicable.

The proximal end of the AnacondaTM fenestrated body device is positioned suprarenally, where it seals and fixates in the vessel by means of rings comprised of multiple turns of fine nitinol wire, attached to the fabric with polyester sutures, creating a self-expanding stent which provides a conformable seal with the vessel wall and assists in anchoring of the device. Nitinol hooks provide secure fixation within the suprarenal aorta. The saddle shape of the rings allows the superior mesenteric artery (SMA) or celiac artery to be accommodated in the valley of the top ring saddle in some cases.

The objective of the registry is to provide long term (5 year) safety and effectiveness data of all patients who consent to their data to be used in the registry. This data aims to demonstrate that the Vascutek AnacondaTM Custom Fenestrated Stent Graft is safe and effective in patients with a short infrarenal neck of <15mm or juxta-renal abdominal aortic aneurysms who, in the opinion of the treating physician, are anatomically suitable for the AnacondaTM Custom Fenestrated Stent Graft.

Primary outcomes

• To monitor the the post-market clinical safety and effectiveness of the Vascutek AnacondaTM Custom Fenestrated Stent Graft [For 5 years post-implant]: To monitor the post-market clinical safety and effectiveness of the Vascutek AnacondaTM Custom Fenestrated Stent Graft in patients with a short infrarenal neck of <15mm or juxta-renal abdominal aortic aneurysms who, in the opinion of the treating physician, are anatomically suitable for the AnacondaTM Custom Fenestrated Stent Graft and for whom a customised medical device is required.
