Eligibility Criteria:
Inclusion Criteria:
* Patient has descending thoracic aortic aneurysm (DTA) or type B aortic dissection (TBAD), who needs endovascular repair (TEVAR).
* Life expectancy \> 1 year.
* Patient or legally authorized representative understands the nature of the clinical trial, agrees to its provisions, agrees to comply with the requirements of the study including a 3-year follow-up, and signed applicable Informed Consent Form.
* Patient's characteristics consistent with Ankura™ Stent Graft System IFU and sizing guidelines, which indicate as following:
1. For descending thoracic aortic aneurysm (DTA) patient:
* Adequate iliac/femoral access vessel that is compatible with the required delivery system.
* Aortic inner diameter in the range of 18-42mm.
* ≥15mm non-aneurysmal aorta proximal and distal to the lesion.
* Morphology suitable for endovascular repair.
2. For type B aortic dissection (TBAD) patient:
* Adequate iliac/femoral access vessel that is compatible with the required delivery system.
* ≥15mm landing zone proximal to the primary entry tear; proximal extent of the landing zone must not be dissected. Diameter at proximal extent of proximal landing zone in the range of 16-44mm.
* ≥15mm landing zone distal to the primary entry tear; distal extent of the landing zone must not be dissected. Diameter at distal extent of distal landing zone in the range of 16-44mm.
* Morphology suitable for endovascular repair.
Exclusion Criteria:
* Patient with any contraindications mentioned in the Ankura™ Stent Graft System IFU:

* Patients who have had other devices implanted in the cardiovascular cavity, which will interfere with the placement of this device;
* Patients with mesenteric blood flow mainly supplied by the inferior mesenteric artery;
* Patients who have allergic reaction to the device;
* Patients who are not suitable for endovascular repair in vascular morphology;
* Patients who cannot tolerate contrast agents due to severe renal insufficiency;
* Patients who are allergic to contrast agents;
* Aneurysms neck with thrombus;
* Non-aneurysmal aortic proximal neck length \<1.5cm;
* Non-aneurysmal aortic distal anchorage zone \<1.5cm;
* For aneurysms, Non-aneurysmal aortic diameter \<18mm or \>42mm. For Type B dissections, Non-aneurysmal aortic diameter \<16mm or \>44mm.
* Patient with traumatic aortic injury;
* Patient with uncorrectable coagulopathy;
* Patient with hereditary connective tissue disease, including but not limited to Marfan Syndrome or Ehlers-Danlos Syndrome;

* Patient with an unstable angina pectoris or hearth insufficiency New York Heart Association Functional Classification (NYHA) 3 or 4
* Participant in other drug or medical device clinical trials;
* Patient with access vessel which are to tortuous, narrow or any kind of reasons that would lead to failure of introduction and advancing an introducer sheath;
* Any condition (medical or anatomic) which makes the patient not suitable for endovascular repair according to the opinion of the investigator.
