Aortic Intervention

Zenith Alpha™ Thoracic now commercially available

The Zenith Alpha™ Thoracic Endovascular Graft is now commercially available in the U.S., following premarket approval from the U.S. Food and Drug Administration in 2015.


With a 16-20 Fr delivery system, Zenith Alpha Thoracic was developed to provide vascular access and delivery with a lower profile device which allows physicians to consider TEVAR (thoracic endovascular aortic repair) options for patients who otherwise may not have been candidates for larger-profile devices.

The device can be used in a wide range of patients with isolated lesions of the descending thoracic aorta (not including dissections) because of its lower-profile delivery system and broad range of lengths and diameters.

The introduction system also features an ergonomic handle and requires fewer procedural steps than previous designs to deploy the device, without sacrificing the precision and control that you’re used to from the Zenith platform.
