Ankura™ TAA Stent Graft System Post-Market Clinical Follow-up Study
Sponsor:

Lifetech Scientific (Shenzhen) Co., Ltd.

Brief Summary:

The purpose of this study is to collect clinical data on patient outcomes, evaluate the safety and performance of Ankura TAA Stent Graft System and Surpass Super Stiff Guidewire, and build clinical evidence for patients with Descending Thoracic Aneurysm (DTA) or Type B Aortic Dissection (TBAD).

Condition or disease

Aneurysm Thoracic

Dissection of Thoracic Aorta

Intervention/treatment

Ankura™ TAA Stent Graft System

Detailed Description:

The physician shall strictly follow the clinical study protocol and shall not deviate from or substantially change the protocol. However, in case of emergency such as immediate risk to the subjects, which needs tobe eliminated immediately, it may be reported in written form afterwards. During the course of the study,documents such as amendments to the clinical study protocol and informed consent, requests for deviation,and resumption of the suspended clinical study shall be subject to the written approval of the Ethics Committee
