Summary

The outcomes from prior clinical evaluation of the study device, including successfully treating 99% (84/85) of the intended target vessels and 96% (27/28) limb patency observed at one year, demonstrate the potential benefits of the device. When contrasted with open repair's significant complication rates and branch fenestrated device's significant anatomic and logistic limitations, the potential risk of the proposed novel graft does not outweigh the potential benefit of widened anatomic availability and improved patency rates. Given the potential benefits, the investigators feel that it is justified to expose the target patient population to the potential risk. The non-clinical testing performed by Medtronic and the clinical results reported by Sanford Health show adequate safety of the device to support an early feasibility study.

The investigators would like to perform an early feasibility study under a defined and controlled protocol to collect prospective preliminary safety and device functionality data. The investigators believe an early feasibility study is most appropriate for this novel approach. The limited sample size allows adequate patient data to be collected under a controlled protocol without exposing a large patient population to the risk associated with a novel device design.

Conditions

  • Thoracoabdominal Aortic Aneurysms

Interventions

DEVICE

TAAA Debranching Stent Graft System

The TAAA Debranching Stent Graft System is made up of two main body components and makes use of several off-the-shelf FDA-approved stent graft components. The two custom main body grafts are the thoracic bifurcation and the visceral manifold. The thoracic bifurcation is deployed in the thoracic aorta and provides the proximal seal for the device. The two limbs of the thoracic bifurcation allows for continued aortic flow while deploying the visceral segment. The visceral manifold is deployed within the larger 20 mm limb of the thoracic bifurcation to set the stage for the visceral debranching. The branches of the visceral manifold extend to the visceral vessel with the use of covered bridging stents and provide distal seal of the manifold.
