The Ankura™ Thoracic Stent Graft is specifically designed for endovascular treatment of thoracic aortic dissection, aneurysm and other relative diseases. It reinforces the vascular wall of thoracic aorta from rupture.
Optimal Proximal Bare Stent
•Allow for deployment across the LSA or LCCA without occluding the blood flow
•Provide extended Proximal Landing Zone
•Less traumatic to the aortic branches
Proximal Sealing and Fixation
•MINI Wave – Enhanced apposition to the aortic wall
•Decreased endoleak risk
•Conform to the natural curvature of thoracic aorta
•Reduce the possibility of kinking
•4mm, 6mm and 8mm taper available
•Self-expanding Nitinol stent – Radial force fixation
•No suture on the main body – Avoid pinhole leakage ( Type Ⅳ endoleak)
•Longitudinal supporting strut on the greater curvature – Avoid stent shortening, provide axial support
•e-PTFE Dual Membrane – Excellent biocompatibility and durability
•Kink-resistant delivery system with Hydrophilic Coating
Information intended for Patients
Magnetic Resonance Imaging (MRI)
A patient after being implanted with the Ankura Stent Graft can be safe to have MRI procedure under the following conditions:
– Static magnetic field of 3.0 Tesla or less
– Spatial gradient filed of ≤720Gauss/cm
– Maximum whole-body-averaged specific absorption rate (SAR) of 2W/kg for 15 minutes of scanning
Expected lifetime of Ankura Device
The Ankura Stent Graft is a permanently implanted device. Under normal circumstances, it will stay in the patient’s body for life, unless it is required to be removed by the doctor’s professional judgment. Lifetech evaluated the durability and integrity of the implanted device. After 10 years simulated physiological loading of 380 million cycles of the implanted device, tested samples were examined visually under 3D microscope with magnification (20x). There was no evidence of Nitinol wire pitting or cracking, nor of fatigue related fractures. The device was intact after 10 years simulated in vivo physiological loading of 380 million cycles, and no perforation or detachment of the ePTFE graft as a result of pulsatile fatigue test.
It is important to schedule regular follow-up visits with your doctor. Follow-up visit will help the doctor to check your aneurysm/dissection and stent graft on a regular basis. The follow up visit should be performed at 24 hours, 1, 3, 6, 12 and 24 months after the procedure, and can be adjusted by the doctor depending on your condition.
At each visit, imaging such as CT scans will be carried out to determine the performance of the stent graft. If you have poor kidney function, you should ask your doctor about the dyes used in some of these imaging studies, as they may be harmful.
Material/Substances in Contact with Patient
The materials and substances to which the patient can be exposed in the implantable device (in wt.%) are NiTi (Nickel titanium, 52-67%), stainless steel (7-16%), PtIr (Platinum-Iridium, 0.5-6%), PTFE (Polytetrafluoroethylene, 20-40%), PP(Polypropylene,<1%).< p=””>
The Ankura Stent Graft implants are composed of Nitinol (48-58%w/w), Stainless steel (6-8%w /w), Polytetrafluoroethylene (PTFE, 35-43%w/w), Platinum-Iridium (<1%w/w) and Polypropylene (PP, <1%w/w). During the intended use, the thoracic aorta, abdominal aorta, iliac artery, femoral artery as well the blood will come in contact with the device.
Note: If you have a history of metal allergies, you should ask your doctor. Your doctor will help you decide whether it is appropriate for you to get an Ankura stent graft.
The Ankura devices do not contain medicinal substances, animal or human tissue; they are no blood products and are not radioactive.

Magnetic Resonance (MR) conditional
▶ Non-clinical testing showed that a patient with an implanted plug can be scanned safely immediately after placement of the device under the following conditions:
● Static magnetic field of 3 T or less.
● Spatial gradient magnetic field of 720s G/cm or less.
● Maximum MR system-reported, whole-body-averaged specific absorption rate (SAR) of 2 W/kg for 15 minutes of scanning.
▶ Based on non-clinical testing, the device was determined to produce a temperature rise of less than 1.5 °C at a maximum whole-body-averaged specific absorption rate (SAR) of 2.21 W/kg for 15 minutes of MR scanning. The maximum whole-body-averaged specific absorption rate (SAR) was derived by calculation and verified by calorimetry.
▶ MR image quality may be compromised if the area of interest is in the same area or relatively close to the position of the device. Therefore, optimization of MR imaging parameters to compensate for the presence of this device is necessary. The image artifact extends approximately 15 mm outside the device lumen when scanned in non-clinical testing using the spin echo sequence and gradient echo sequence, respectively in a 3.0 T Scanner with a whole body coil.
Material/Substances in Contact with Patient
The materials and substances to which the patient can be exposed in the implantable device (concentration in wt.%) are: NiTi (Nickel titanium, 54%-68%), stainless (9%-37%), TiN (Titanium Nitride, ~0%), PA (Polyamide, 0%-1%), PTFE (Polytetrafluoroethylene, 8%-23%).
The expected lifetime of the device, including data on implant survival rates:
The device is a permanently implanted device. A fatigue testing to simulate in vivo use of the device for 10 years was performed and the results are satisfied: the metal wire of vascular plug has no breaks or cracks, and the connection points of the metal wires are not loose, the plug is not migrated and its head is intact. Under normal circumstances, it will stay in the patient’s body for life, unless it is required to be removed by the physician’s professional judgment. No special attention is needed by the patient.
It is important to schedule regular follow-up visits with your doctor. Follow-up visit will help the doctor to check your heart on a regular basis. The follow up visit should be performed at 24 hours, 1, 3, 6, and 12 months after the procedure, and can be adjusted by the doctor depending on your condition.
