Study type
Interventional
Description of intervention(s) / exposure
A single-arm, multicenter, non-randomized open study that will include up to 100 study participants implanted with ACURATE neo Trademark and its Transfemoral Delivery
System. The study will collect data from study participants treated with the ACURATE neo Trademark and its Transfemoral Delivery System following standard TAVI practice at each participating center. All study participants will be followed to 12 months after the implant procedure. The study is divided into two periods:
1) Implantation procedure (immediately pre-implant to 24 hours post-procedure)
2) Follow-up period (discharge or 7 days, whichever occurs first, at 30 days and at 12
months)

Prior to implantation, the Bioprosthesis is carefully loaded onto the Delivery System using aspecially designed loading tool.
The Bioprosthesis is inserted into the femoral artery through a compatible introducer sheath and delivered retrograde to the implantation site using the Delivery System.
The Bioprosthesis is positioned and deployed over the stenotic, native aortic valve and the Delivery System is then removed. This minimally invasive transcatheter approach is intended to be performed under general or regional anesthesia as per the physician’s standard of practice using sterile technique, with echocardiographic and fluoroscopic guidance for visualization.
