The ACURATE Prime XL Human Feasibility Study (ACURATE Prime XL HFS) is a prospective, multicenter, open-label, single-arm study designed to evaluate feasibility and safety of the ACURATE Prime XL Transfemoral Aortic Valve System for TAVI in subjects who have severe native aortic stenosis and are indicated for TAVI.~Subjects who provide written informed consent, meet all eligibility criteria, and are approved by the Case Review Committee (CRC) are considered enrolled when an attempt is made to insert the iSLEEVE Introducer into the subject's femoral artery. There will be up to 20 subjects enrolled at up to 6 centers in Australia and Europe.~All subjects implanted with a study valve will be assessed at baseline, peri- and post-procedure, at discharge or 7 days post index procedure (whichever comes first), 30 days, 6 months, and 1 year. Subjects who are enrolled but not implanted with a study valve at the time of the procedure will be followed for safety through 30 days.
To evaluate feasibility and safety of the ACURATE Prime™ XL Transfemoral Aortic Valve System for transcatheter aortic valve implantation (TAVI) in subjects with severe native aortic stenosis who are indicated for TAVI.
