ACURATE TF™ Transfemoral Aortic Bioprosthesis for Implantation in Patients With Severe Aortic Stenosis (2011-03)

Not Applicable

Completed

• Conditions: Aortic Stenosis Symptomatic

• Registration Number: NCT03752996
• Lead Sponsor: Symetis SA

Brief Summary

First-In-Man Study on the ACURATE TF™ Transfemoral Aortic Bioprosthesis Implantation in Patients with Severe Aortic Stenosis to collect human feasibility data pertaining to the safety and performance of the device.

Detailed Description

A single arm, prospective, multicenter, non-randomized, open trial, up to 5 Years follow-up with the Symetis ACURATE TF™ Transfemoral Aortic Bioprosthesis for minimal invasive implantation via transfemoral access to treat patients with severe aortic stenosis where conventional aortic valve replacement (AVR) via open heart surgery is considered to be associated with high risk.
